Best glasses for high prescription lenses - My top tips for thinner and lighter lenses 

I’m plus 5 with an astigmatism in both eyes. Would really like an idea of how much glasses with thin lenses would be as it does effect my self confidence. Thanks

@@jambutty2218 hi, thanks for watching and commenting 🙂 There are a few things to consider. The prices will really depend on a few factors. Firstly the material of the lenses. With your prescription a standard index material (1.5) will be the cheapest but the heaviest and thickest, where are if you go up to a 1.67 for example (higher the index= thinner the lenses in general) the weight and thickness decrease but the price will normally increase. So combine a better material with a frame that suits your facial and eye measurements, don't go really big and square. Smaller the frame the better really/closer to your measurements etc. What do you currently wear shape wise?

My lens power is -6D(-5 cylinder &-1 spherical what type of lens material(refractive index) and others do i need

My pleasure, thanks for your support!

Hi Harish, thank you for your kind words. Glad you enjoyed the video. Thank you for your support and glad I could help 🙂 Keep safe. Colin 🤓

Hi Zach, thank you. Appreciate your time and for stopping by to let me know. Glad you liked it. Keep safe! Colin 🙂

Thanks for watching and your comment too 🙂 Glad the video was useful 👍

Hi Lizzy, interesting, what type of frames do you wear?

@@precisionopticseyewear I’m guessing a smaller frame, with high index and perhaps even aspheric lenses would be perfect?

Thank you for watching, much appreciated, glad you found it useful 😎👍 Colin

Thank you! Let us know if there is anything elses you might want to know more about, thanks for watching!

My pleasure. Thanks for watching 👍👓

Hi Lena, thanks for your comment. So there can be many factors as to why your lenses are heavier. As you noted, the increase in the prescription change will have an impact (can't say how much) and other things such as your Axis changing can effect thickness etc too. So if this area on your prescription has changed, and the increase in your prescription too, then you may well notice things. I would pop back to your supplier and get them to have a check over them. You can always look at a 1.74 index lens, your supplier will be able to make a pretend order up with your details to generate some expected lens thicknesses if you had the same in a 1.74, this way you could tell if paying the extra etc is worth it before doing so. Hope this helps Colin 🙂

Hi, thanks for watching and for commenting. With something like this in terms of getting a frame and lens combination that will be low cost will be tricky. One of the main ways to get the thinnest lenses with the lowest cost is to get the right frame shape. Hard to give advice on here without seeing you, but go for a frame that is relevant to your own measurements I.e pupil distance and head width, this will greatly help the lens thickness plus, picking a frame with these requirements has nothing to do with price, you can find a suitable frame on any price range. The money part comes into play when we look at thinning lenses. Obviously the top end thinning will be better, but you can still go for a good lens that isn't too expensive compared to the high end options. Maybe look at a 1.67 index lens and the price of that? Hope this helps 🙂👍

My pleasure, thanks for watching 😊

Thank you Nickel, much appreciated. Thanks for watching 🙂

Hi, thanks for watching and for your comment. It should be possible, it's more of a question of if it's something that you would actually want to do. Having a thin eye rim will show lots of the edge thickness. Over the years I've seen many clients who have purchased frames from elsewhere as they are marketed as thin and super light, then people with high prescriptions get these as they think a thin frame will help. It actually does the opposite as it just shows the thickness so much more. I'm not saying not to have it, I'm just saying this about the aesthetics of the finished job, as you need to weigh up a couple of options.

Thank you for your message, basically yes it does matter. But don't got by frame measurements 100% of the time as it's more about how the frames sit on you, everyone's bridge and face is different. A good rule is to make sure that there is atleast 10mm from your pupil to the top of the frame rim, more is OK too. Any smaller and if it slips down you'll be looking at the top rim. The vertical measurement when you have your lenses made is important at it helps create better vision as you'll be looking through the nearest centre part of the lens. Hope this helps. Colin

Hi, thanks for commenting 🙂 With this particular model, the top part (thick part) will hide the edge thickness great (providing whoever makes your glasses positions the lens correctly when cutting to give the best look) The bottom part, as you noted is thinner, you are going to see the edge thickness regardless of what you do to be honest with all due respect. With a minus 8/9 prescription, you are not going to get it 3 or 4 mm thin to match the rim thickness. You could maybe push and go to a 1.74, you may notice a difference. Maybe look at the same style without the split frame style, more like a full acetate frame maybe. Hope this helps. Many thanks, Colin

omg! we have the exact same sph, cyl, and axis!? Have you gotten your glasses yet? If yes, what index did you get and do you think it was better overall?

Hi Tracy, thanks for your question. Hopefully my recommendation on the other platform helped you out. Thank you yet again 🙂👍

Hi, thanks for your comment 🙂 To be honest there is no reason for you not to have a brow line frame and in fact, it could actually complement your type of prescription, especially at the temporal (outer higher edges of the lens) as this is the thickest part of the frame and also the same area the most thickness normally occurs. Just think about the lower part of the frame, as most browline frames will have a traditional thinner rim which will show a bit more lens edge thickness. If the people making your glasses are careful, they will be able to glaze you lenses so that he majority of the lens thickness is hidden by the rim. Hope this helps 🙂 p.s go for a hi index lens too 👍 Many thanks Colin Precision Optics Eyewear

Thanks for your comment. So basically there will be various thicknesses around the entire lens, this is due to all aspects of your prescription, these can ofcourse change over time resulting in differences in looks. A thin wire rim at the bottom is going to show more lens edge naturally rayher than a thicker plastic frame, even in a 1.74. With your prescription you shouldn't notice a thickness being increased at the bottom in respects due to the prescription, but with your cyl power and axis combination you will see changes in thickness here.

@@precisionopticseyewear Thanks! I really enjoy your videos.

Same concern. Hope you'll answer this one 🥺🥺

Hi Kemi and Maria. OK so this is a super common issue with high minus prescriptions. One of the biggest reason I find that this happens is when you may have a small PD (pupil distance) and a wide frame. This creates a lot of excess lens and the increased width then creates what we call facial inset. There isn't a specific go to fix or a product that fixes this. It's important to get the rigjt size and shape frame which will be different from person to person. Try to find a narrower frame that isn't as wide and make sure the lenses are close to your eyes as this helps reduce the effect of your eyes looking small too. Hope this helps! Colin

Hi, thanks for watching and commenting 🙂 Ok, so you might want to go for a nice acetate/plastic frame, something with some thickness to help hide the edge thickness due to the astigmatism (obviously hard to advise as I don't know your prescription) and then look at rounder frames to help with thickness (again only relevant if your prescription/astigmatism is high). You can then combine that with a thinner and lighter lens, this will help reduce overall thickness whilst reducing the weight of the lens. Hi index lenses are normally UV protected too which is great! What type of frames do you wear at the moment?

Hi, where abouts are you located please so i can help out 🤓

Thanks for your question. It's called facial inset and this is a result of your type and strength of - prescription. What shape and size frame do you wear?

Do you mean the round one in the video?

Hi, thanks for watching and commenting. It's easy to think that the frame off the rack will be the same as the finished piece with your prescription in. With a -4.75 prescription they will be a bit heavier and as you rightfully noted, thicker. If you go for a semi rimless (supra frame) then you are going to have some elements of the frame exposed (the lower bottom portion and sides of the lens) the edge of the lenses will be visible. They will (should) however polish the edges to make them look nicer. One thin you can do is have a full rimmed frame, even a slightly chunkier plastic/acetate frame, as this will help hide the thickness of the edges of your lenses. And yes, a 1.74 is a hi index lens which will help reduce weight and thickness too. What do you currently wear at the moment (frame style etc)

@@precisionopticseyewear I currently wear a plastic full frame style. I wanted a change and opted for the semi rimless but with 1.74 to help reduce some of the thickness of the lens. Now Im worried Ive made the wrong choice!!?

See how they are when you get them. I know it's not ideal, but if you aren't happy then just let them know, most places who have your best interests at heart will resolve any issues you have, obviously within reason. The main thing is management of expectations, being told about the different frames choices, the edge thickness and polish etc. See how they are, you may be pleasantly surprised to be honest. Where abouts are you located?

Thanks for your message, so with your prescription I would steer away from a large square shape. Depending on what your last glasses prescription was, gauge if the lens material (what level of thinning you had) is to your liking. For example, if your prescription hasn't changed much at all, and you had a 1.6 high index lens last time in a fairly big square frame, then try a change of frame shape, go smaller and softer/rounder and keep to the 1.6 index if this wasn't too bad, obviously this is hard to help fully without seeing said glasses, but then hopefully by picking a better suited frame this will help with the thickness anyway, find out what index lens you had last time (level of thinning) and then gauge the price increase to the next level to go one level thinner, combine that with a suited frame as mentioned above then you should get yourself a nicer pair of lenses and frames. Again, I mentioned this with another query, try to get a frame that has the same frame PD as your own PD. Whoever is dispensing your glasses will be able to assist with this. Hope this helps. Kind regards Colin

Precision Optics Eyewear is there a way I can send you a picture of my glasses

Precision Optics Eyewear would you suggest something like this is what your talking about www.visionworks.com/ctm-5037/product/0405015685037

Hi Hans! Appreciate your support and thanks or watching. Great question, so yes to you going for a 1.74, that's a good idea with your prescription. With regards to the frame, naturally the thicker the rim of the frame, the more edge thickness it will hide of the lens. Going for a thin rim will show more edge thickness but that is to be expected with many prescriptions any way. The eyesize you refer too sounds good but it is always relevant to your own pupil distance and own facial measurements. But as a rule of thumb any smaller eye size will contribute to better lens thickness especially as the lens shape is rounded. Overall, without actually seeing you face to face, I would say this all sounds like a fairly good combination with some good points that you have mentioned and that you are aware of. Final note, I wouldn't have the lens edges polished as you may notice internal glare when wearing them, even though they can look better, the visual clarity can be reduced with a thick lens edge combined with a high polish 🙂 Hope this helps, keep safe and thanks for watching 🤓

@@precisionopticseyewear hi there, thank you so so much, this information has helped me out immensely! You’ve got yourself a new subscriber 😎 I think I am going to purchase them now! Thanks again

@@hans8201 my pleasure. Really appreciate your support, thank you! Keep safe and get in touch if you need anything. Thanks for the sub too 🙂👍

Hi Sarah, sorry to hear about your eye! Unfortunately anti-reflective coatings will not help. With this type of prescription the main thing is frame shape and style, combined with a high index lens like a 1.74 index lens materials. Hope this helps 🙂

Hi Joseph, thanks for watching and for your comment. So with your prescription, I would say it's worth your optician running a couple of dummy orders through with his lab. They will be able to tell you the estimated edge thickness with a 1.67 and a 1.74. Sometimes the difference isn't enough to warrant the price increase, but if there is a fair difference when running a couple of dummy orders through for measurement purposes then you have your answer depending upon the price difference. Running a couple of dummy orders will take literally minutes and is zero cost to anyone as it's all computer generated. Hope this helps 🙂 Kind regards Colin

Hi Kady, thanks for watching and commenting. I wouldn't worry. Our eyes can change at any point and don't let the numbers worry you. The main thing is that you have had your eyes checked and also the health of your eyes checked too. Hope this helps. Kind regards Colin

Hi, thanks for watching and commenting 😎 Firstly the model is Superdry Goro. It's a bit of a unisex model but it's a great frame 👌 With regards to your prescription question, your right eye prescription may say 0, which is equal to 180 as when we work with prescriptions we work between 0-180 degrees. So for example where an old prescription may be axis of 179 and a new prescription may be 2 the some people think it's really far away from the old prescription, when in actual fact it's only 4 degrees away and not 177 away. Hope that helps. With regards regards the thickness, your lens thickness will be determined by your frame choice, facial measurements and also the materials of the lenses, all of these combined factor in to the end results. Look for what we call a high index lens. A standard lens is a 1.5 index. The higher up the index we go, the thinner and denser the materials, so basically the next thinning would be 1.6, then 1.67, then 1.74 etc. There are others but this is the basics which to be fair I find are OK. As you go up the indexes the price will probably increase but the results will be better potentially regarding the thickness and weight. Many thanks Colin

Hi, thanks for your question. Yes you are correct, a thin metal frame will expose an element of the lens thickness. Even thinning the lens down, you will no doubt see the edge thickness. So, yes, a plastic frame will help in terms of aesthetics providing that the person making and glazing the lenses does it in a way that sits the lens in the frame the best way. Hope this helps. Colin

@@precisionopticseyewear thanks for replying sir! One final question what frame shape would fit in an oval face?

Hi, much appreciated, thank you for watching and for your feedback too 🙂 Also, Merry Christmas 🎅 I can't really comment on whether this is safe or not, I would however not recommend altering your prescription on your own, if you are used to a set prescription and this new prescription is giving you discomfort then I would see your optician again. Sometimes the new prescription issued technically is the correct prescription for your eyes, but sometimes ig there is a fairly big change, the eyes and brain cant tolerate it, sometimes a middle ground is used where the optician may give you a prescription in between the new and the old, then the next sight test in a year or two for example would then get you to your strongest prescription, by doing this, it's a longer process to get to the prescription but a more manageable process for your eyes and brain. It's worth mentioning to the optician that your older glasses are better as they will be able to take this into account atleast. How long have you had the new glasses for? As sometimes it can take a while to adjust to a new prescription, especially if you have had quite a jump in power. Obviously I'm not giving medical or clinical advice here, this is just my opinion 🙂 Hope this helps! Kind regards, Colin

@@precisionopticseyewear Thank you 😊 I'll really put this into reconsideration when I visit my optician. To be honest,I don't want to be over-dependent on glasses that's why I'm opting for a lesser prescription maybe to train my eyes to see better idk😂 and also for when I'm running errands such as reading and just going out but thank you for your time. I'm definitely subscribing!

@@hopem6213 my pleasure, and thank you for supporting me! Yes, definitely worth a chat with them, even a quick re check could get you seeing again properly or even just some good advice from them. Keep safe and have a great Boxing Day 🎅🎄🍗

Hi, what you are referring to is a effect called facial inset, is is more to do with your prescription and frame shape/size combination. A higher index lens would give you a thinner edge thickness but not necessarily a better result with the effects you a re experiencing. Try a smaller frame too, what shape do you have currently?

Hi, thanks for watching and commenting 🙂 I'd probably go for the 1.6 based on the fact that it would no doubt come with an anti reflective coating as standard (most 1.6 and upwards lenses come with this as standard) plus it will have UV protection qualities due to the material, there may be a slight price difference but not enough to not go for it given the benefits. If your saying your right is a -3.25 and the left of a -1.75 (both SPH) then you could effectively have just a standard index (1.5) in the -1.75 lens and a 1.6 index in the other (-3.25) this would help balance it out. There is no really benefit to having a 1.6 with the lower prescription, but the 1.6 is a stronger material and some suppliers like to use that with semi rimless frames. What do you currently wear?

@@precisionopticseyewear hi thanks for your reply. Currently I’m wearing full Rim plastic frame so I guess 1.56 or 1.5 is sufficient. But now I’m changing into a new glasses semi rimless, and the optician suggested me to go for 1.6 index for both left and right. I’m still contemplating whether 1.56 is already good enough for the lower prescription. And take 1.6 for the higher prescription as per what u mentioned. Thanks again

@@MrDeadXSouls my pleasure 🙂 yes, with a full rim plastic you would probably get away with no thinning. With the semi rimmed you will see more edge thickness as there is nothing to hide it. With your type of prescription, the thickest part will be the outer edges, and with the supra frame it will no doubt have a polished edge finish. You might notice a little bit of a difference wearing them due to the edge polish on the thicker lens as it may give off some more reflections than what your used to. Might not even notice it at all but thats one thing I would keep in mind. Is it a big frame or relatively small?

Hi thanks for watching! Ok, so with your type of prescription your lenses will be thicker on the centre and thinner at the outer edges, this is because of your type of prescription. With this type of prescription you will best getting your lenses surfaced (made) specifically to your frame dimensions and facial dimensions. When a lens is made specifically considering the frame dimensions, a technique can be applied called "knife edge" or METs (minimum edge thickness). This is when they try to make the edges as thin a is possible. The centre thickness can be worked by 3 different ways, by meeting all 3 ways will ensure the thinness lens possible. 1- pick a frame that isn't too large, picking a frame that has similar measurements to your facial measurements. 2- using a lens that is a higher index, this reduces the weight and thickness of the lens. 3- try to pick a frame that isn't to square or angular, smaller the frame will mean less lens and less thickness = less weight. There are lots of other techniques and things that can be done, these are just some of the basics. Think about the frame in terms of aesthetics, a thicker rimmed frame like a plastic frame will help hide a decent amount of the lens thickness and depending upon who is making your glasses, the lab technician can position the lens bevel in a way to help sit the lens best in the frames. Hope this helps. Colin 🙂

Hi Jay Thanks for watching and for your comment. It's a tricky one to say as it really depends upon the quality and procedures in place with online suppliers and/or Opticians. Even though the Opticians seem higher priced, there would probably be a higher level of accuracy with regards to measurements and fitting. As you well know, especially with your prescription, the lenses and fitting of the frames are really important. It may he worth while trying a few different physical store opticians to get some quotes as there may well be a price difference and a bit of a saving to be made. By no means am I suggesting that an online provider wouldn't be able to successfully complete your order, it's just something you have to weigh up the pros and cons. Is the extra money worth the extra accuracy and end result potentially. Things like after care service and returns terms are things worth looking at as your lenses will not be "cheap" wherever you go. Hope this helps. Colin 🙂

@@precisionopticseyewear hi Colin, thank you so much for your time & response! 🙂 Covid will make it a bit challenging, but I will definitely check other opticians. Just one last question. What frame size would you personally recommend? The last glasses I got (from 2013), they recommended me a plastic rectangular frame with hi index 1.67. Also, is 1.74 a big difference vs 1.67. I'm willing to pay extra assuming 1.74 would be beneficial for me.

@@jayg4540 my pleasure, no problem 🙂 Personally I'd suggest go rounder in frame size. This will help reduce edge thickness and therefore help contribute towards reducing the weight of the lenses. If you go rectangular then your not helping matters. In terms of lens materials 1.67 vs 1.74... with some prescriptions the difference is so small that it isn't worth the extra cost, but I would suggest that your optician runs two duplicate orders as dummy orders with the lab(lens manufacturer) one as a 1.67 and one as a 1.74, they will be able to calculate the edge and centre thickness. With that information you can then determine if you want to pay the extra. With regards to best frame measurements, pick a frame that has a frame PD the same or as close as your own PD (pupil distance) . A professional helping you will understand this part. The frame has to be apparent to your own measurements as there is no set rule for this. Many thanks Colin

1.74 index lens, make sure your total pd per lens is equal on the frame pd rounder frames. Then I read the answer after. I am a high myope. And doing endmyopia. Makes a massive difference

@@hybridangel3403 thanks for the response. I'm getting conflicting info. The opticians at Lenscrafters & Walmart Optical told me to go for small rectangular frames (what I currently have). I'm thinking they may just be telling me that since they see that's what I'm wearing. So IT IS in my best interest to get small round frames instead right? How do I make sure the total pd per lens is equal on the frame pd? Should I be looking at the frame size? My current frame size is 54. My pd is 65. Lenscrafters is recommending me to get a frame size 50 for an ideal fit which narrow my glasses choices down to about 5 different frames unfortunately (the rectangular shape being the only ones they were showing me). I usually wear contact lenses (Coopervision Hydrasoft Toric), but ran out during covid & then found out they were discontinued. So now waiting on a custom trial lens of Biofinity XR Toric. So I will go back to Lenscrafters soon for my contacts (assuming they arrive) & just want to know what to look for in glasses ahead of time vs relying on the opticians who have been giving me conflicting info. Thanks for all your help thus far! My last glasses that I'm currently wearing are from Sears Optical 2013 & I've been riding on those which are pretty wore out now. Always had a high prescription since I was a kid, but never this high (went from - 13 in 2013 to - 16.5 now in 2021) which has a made it more challenging ordering glasses. I paid 250 from Walmart for 1.67 hi index (the highest they offered) & I'm returning them because I wasn't satisfied with how the lenses came out. Hoping for a better experience at Lenscrafters with a 1.74 & since they have a higher end lab through Luxottica from what I understand. Also, what is endmyopia? Hope I didn't overwhelm you with the long reply.

Hi, Happy new year first of all! Thanks for watching, yes, a hi index lens can be used with you prescription. You can technically have any index you want to a degree, but you probably wouldn't benefit by having the highest possible thinning, maybe a 1.6 index or a 1.67 index would work well. The extra cost for the highest (1.74) probably isn't worth the extra money given you wouldn't see that much benefit compared against a 1.67 lens. Combine lens thinning with a rounder and smaller frame (frame that fits well against your own measurements) to get the best thinning possible. Hope this helps. Let me know if you have any more questions. Kind regards, Colin 🤓

@@precisionopticseyewear happy new year to you also.... will this 1.6 index can really make my -3.25 glasses looks thinner and one more question that few days earlier any optician shop recommended -3.25 eyelense it is weird as my power havent increased since last 4 year but i am sill feeling good and relax experiencing same vision in my old glasses of -3.00 glasses should i wear this 3.25 or. I continue with my old glasses of -3.0

@@Farziwada_ thank you. I can't give clinical advice over here, but I would follow the guidance of your optician. If you feel comfortable and used to your current ones, then this is because you are used to that prescription, the new prescription may feel strange or too strong to start with, but the jump between prescriptions isn't very high to cause anything major I wouldn't think, you would probably get on fine with the new prescription and should notice an improvement in vision, maybe after a little bit of time getting used to them. Think of it like wearing an old comfy pair of shoes, they are worn in and you are used to them, you then notice how the new ones feel until you wear them in a bit. Yes, the 1.6 or 1.67 will make a difference, how much though depends upon your measurements and frame choice. Hope this helps 🙂

Hi John, thanks for taking the time to watch and for your comment, much appreciated. Interesting, yes the interesting thing with rimless, especially with prescriptions such as yours, is that we would typically use a higher index material, thus strengthens the lens and also makes it thinner, ironically, sometimes we have to actually artificially increase some areas as they can be too thin, so im some cases you counteract it. It's always an area that I try to make my clients fully aware of, as there is always the visible edge thickness regardless of prescription strengths, sometimes people think they will look like the display lenses, unfortunately that is rare to have the exact outcome. Also differences in ke ses such as yours with about a 2 diopter difference in power can create asymmetry with lens thickness, you can however apply different thinning options to individual lenses but this equally has its pros and cons. Do you have all your eyewear thinned down ?

@@precisionopticseyewear I’ve always opted for the highest index available, and I always have them photochromic grey as well. The one’s I’m using now are around 4mm thick at the outer edge on the right, and 3mm on the left. A lot better than the old glass lenses. The pair in use now are progressive. I seem to remember that when I switched to using these, the optician I used was a bit sceptical as to whether they would work, given the difference between left and right, but it seems to work. They are about 54 x 40 mm size. Before I started using progressive ones, I used narrow (vertically) fixed focus ones, so that I could easily look under them for close up reading. A bit like a bifocal arrangement which is kind of all or nothing, and with no frame it’s a narrow edge at the bottom.

Hi Logan, thanks for your message. Ok, so the three you have mentioned are all premium, high quality makes, all of which we use. In terms of quality, they are all great, they all have their own range of coatings and names etc. In terms on longevity, I know that essilor and hoya both do coatings that have a scratch guarantee for general wear and tear, which they will replace the lenses within 2 years, essilor will replace for general light scratches or wear and tear, where as hoya will replace for more damaged lenses such as bad scratches and scrapes. I know Zeiss do high quality coatings but I don't think they do a 2 year replacement like hoya and essilor (I will need to check this). From experience of making hundreds of pairs of glasses with said lenses, you would be best making your decision based on what you are using the lenses for, so are they for varifocals? Single vision long distance etc? Price wise, you will probably find that hoya is cheaper than essilor across the board, as for zeiss they may sit in between the two, if not slightly higher to essilor, depending where you are in the world. Let me know what you need them for and I can advise you further. Many thanks Colin

Precision Optics Eyewear many thanks Colin. Yes I use for single vision long distance. I’ve currently have the Hoya sensity transitions with their coating. Has lasted me for 3 plus years now. I’m thinking of getting a new pair and the new gen8 transition seems promising. Was wondering if that lenses came with all the standard coatings. Thanks again Colin.

No worries at all. Ok, so in terms of availability, hoya do not use the transitions brand, they use their own brand called "sesntity". If your going the hoya route, you would go for a hoya sensity 2 (this is the equivalent to the new gen8 transitions) with the long life coating. If you go the essilor route, you would have the sapphire coating with the gen8 transitions. In comparison to the gen8 transitions and the sensity, both are upgraded version of the previous technology, formerly sensity 1 and transitions gen 7. They both react dark and go clear quicker than the previous design, with other elements improving too. The other option is to have transitions xtractive or sensity dark, both of these (from hoya and essilor) are advanced version of lens which react more to visible light, go even darker and work better in the car behind a windshield, however, both will have a very very slight residual tint on, which is very light, but still legal to drive in (in other words they will never go fully fully completely clear). Both of which can have the coatings applied too. Hope this helps. Are you in the UK?

Precision Optics Eyewear thank you so much. That really helps. No I’m in Aussie. Thanks for clearing my questions. I know what to do now. Love Hoya they seem more durable. But the new transitions have cool colours with their lenses tempting me to switch! Thanks again mate. So helpful

@@lsiv12 no problem at all, my pleasure. Yes, they do have some cool colours. We also do a mirror transition lens that's pretty cool. They are nearly fully clear with a slight sheen to them, then go full mirror in the sun. Theres a video on that on my channel for you to see, another option to play about with 😎 All the best, thanks for you time 🤓👍

Hi Nancy, thank you for your comment! Interesting, there is more than one aspect to this, the frame shape and the lens material. Whilst polycarbonate has some fantastic benefits....there are materials that may result in a thinner lens, more specifically the edge thickness. Polycarbonate may have been used as not all labs can make a bifocal in other materials. In terms of frame shape, a round frame which has measurements relevant to your own facial measurements will naturally help reduce thickness, avoid large square frames. What materials have your opticians recommended for this new prescription?

@@precisionopticseyewear I think it’s called digital lenses. The optician, a new store for me, said those lenses are available with lined bifocals.

Hi, thanks for watching and commenting. The lenses can be made, but the problem you will have is that the rimless mounting parts may not be long enough (if a plug mount type). If it's a screw nut and bolt then you may be able to get bolts long enough to go through the thickness. Another thing worth noting is that a high minus prescription like this may give you quite a bit of internal glare/reflections due to the edge polish. Hope this helps Colin

@@precisionopticseyewearcan I use antiglare glasses

@@mansipatel6377 yes, the anti glare you are referring to is a treatment coating applied during manufacturing. With your type of prescription a hi index lens will be used. When using high index lenses anti glare is normally added as standard procedure to help with the clarity of the lenses. You will be able to tell if they have a traditional anti glare as the lenses will have a coloured reflection, probably a green or a purple colour.

Hi Sandra, thanks for your comment. Your prescription justifies a thinner lens, but I wouldnt say you HAVE to have a thinner lens. It depends on what you normally have, what your used to and your frame choice. Personally I would say even some like a 1.6 or a 1.67 at the most would do. Your prescription isn't high enough to warrant the thinnest 1.74. Sure, you could go for the thinnest (1.74) but with your prescription there is going to be hardly any difference between that and 1.67 probably, even if there is a difference, probably not enough to warrant the extra spend. I'd try the first level of thinning and look at something like a 1.6 index thinner lens. There are many thinning options available on the market, laying the highest doesn't always get you the best result. What do you normally have and what kind of frames do you wear? Hope this helps 🙂 Keep safe. Kind regards Colin

Thank you for answering so swiftly. I'm looking at a medium frame with standard 1.59 lenses and transitional maybe transitions XTRActive but I want the lens to darken quicker, is there such a thing or is it a ploy to get more money?

@@peppermint4425 my pleasure 🙂 yes, the xtractive is the more advanced version of the standard transitions brand. Xtractive will go darker quicker yes, but it has no relation to the lens material as you mention Poly ( polycarbonate 1.59 index). Do you usually have polycarbonate? As Polycarbonate does not always offer the best optical clarity compared to say a hi index 1.6 etc. If you are used to poly and have this anyway then you should he fine/used to it. If not, I would go for a 1.6/1.67 index with xtractive. Especially as polycarbonate is usually polished on the edges as part of the finishing process, this polished edge can cause issues with internal reflections with minus prescriptions, albeit the problem may be more noticeable with a higher prescription than yours, yet again, it's a question of if you have had this before also?

Hi Jesse, thank you for watching and commenting 🙂 Are the lenses that you are having difficulty with a new prescription/order?

@@precisionopticseyewear Ive had these glasses for about a year or two I think and they are just from walmart. I don't really know where they got the lenses specifically from but I just chose a pair of glasses at walmart and then gave them the degree on my glasses and they just get it for me. Distortion in pictures is really my biggest issue because close pictures look really odd and it only ever looks normal when im far away from any picture.

sorry, I don't really know what you mean by a new prescription/order. I have had glasses most of all my life but I really don't know much about them or cared to research into it either. Also apologize for the late response, idk why youtube never notified me on this comment.

@@jesseehh5234 no problem at all. So basically the question was about the new prescription/order was to work out whether this is a new pair that you have recently purchased or a pair that you have owned for a while. I think it's worth visiting your optician for them to have a look. It could be various things, anything from a change in prescription, different measurements that you need ir what your eyes are used to, even the material of the lens and the angle and distance of the lens from your eyes can all make a big difference when it comes to higher prescriptions. Our eyes are sensitive and they can change either quickly or slowly over a long or short period of time. Let me know what they say as it would be interesting to see what the outcome is for you. Hope this helps. Colin

@@precisionopticseyewear oh i just re-read my first paragraph and I think I was on a whole nother topic. I just wanted to search for place to get glasses that doesn't cause that huge distortion in pictures. www.damiensymonds.net/2015/10/glasses01-1.jpg that's an example of what im talking about. It makes pictures just look really weird. I have no issue with seeing with my glasses at all. Sorry for the confusion.

Thanks for watching and for your question 🙂 So with a thin eye wire you will see an element of the lens thickness, especially at the outer edges. Going for a round frame will help reduce the thickness naturally as opposed to a large square frame. Your supplier might be able to run a could of checks in their lab to analyse the difference between the thickness of 1.67 or 1.74. Aspherical may potentially give you a nicer outcome but i think some suppliers automatically only supply some higher index in Aspherical. Try and for a round frame that is in good relation to your own eye measurements and that isn't too wide or excessively large. Hope this helps Colin

Go for the 1.74...

It wouldn't really benefit you too much, unless you had a super bird frame, the difference would still be negligible compared to a standard lens type. I personally would just have a standard index lens with a nice anti reflective coating as this will help with the aesthetics too, especially from people looking at you, it reduces the how noticeable the lenses are and ot also reduces the bright white reflections when in photographs etc 🙂

@@precisionopticseyewear thanks for the response. Actually my main goal is making the glasses as light as possible so that it feels like there's nothing on my face. So even if the high index nothing for my vision,I still get the lightweight benefit. I also want to go for rimless so if high index is more durable that's another plus to buy high index

@@snake1625b my pleasure. Then based upon what you have said, hi index will be the best option. A standard material and index lens would not he strong enough for rimless, so you would have to go for a hi index or a polycarbonate lens anyway. Probably something like a 1.6 index will suffice. You don't need the highest such as a 1.74, I think you may be wasting your money with something like that, but see what your optician says as they will take into account your frame choice and measurements etc. Plus if you have a hi index lens lens then they should be UV protected as standard and would normally come with a anti reflective and a scratch resistant coating as standard, but check this before hand. Hope this helps.

Thank you for your question. It's also important to remember the other parts of your prescription. What is the SPH number?

Hi Jeremiaha, thanks for watching. A high minus prescription like yours will require two main things, the tight frame shape and size for your face and also a thinner lens (a higher index lens). What shape glasses do you have at the moment?

Hi, thank you for watching and for your comment. I'd look at atleast thinning down your right lens. If you do this then you can keep both lenses looking similar by having an anti reflective coating applied to right and left lenses. Depending upon how much you thin the lenses by, you may want a smaller rounder frame, but it depends on your face shape and what you are used to. Many thanks, Colin

@@precisionopticseyewear thank you for answering me :)

Oswaldo, your prescription is nothing. We are talking about prescriptions of -10 and higher here. You are not even close to that territory.

This is just a brief overview of lens thicknesses, it can be quite in depth but found that this video has helped explain the basics nicely. Thanks for watching!

Hi Sarah, thanks for your message and for watching. I get asked this many times, I know how much of a problem this is. Unfortunately I do not know of anything to make your eyes appear larger, but make sure that you take time picking a frame that isn't too wide, this can potentially help 🙂

Its has been said that the higher the index the less the eyes becomes smaller. I would suggest to take the highest i dex lenses 1.74 or 1.91

​@@oeshkoer Higher index has no (positive) effect on the "eyes appear smaller" issue (facial inset). The only thing that helps are contact lenses or a mix of contact lenses and low prescription glasses.

Hi Den, with a - prescription, you would normally find this makes your eyes smaller. Thanks for watching, hope this helps 👍

Hi Mani, thank you for watching and for your comment too. Please could you clarify what you exactly mean please? Do you mean the best for when out side in the open as opposed to wearing them inside? Many thanks, Colin

@@precisionopticseyewear sir I'm wearing a high plus power proscription glasses. So my eyes look bigger in my glasses.how to avoid it Wich type of frames is best for this....? sir thank you.....

I would suggest a smaller and rounder frame. Look at thinner lenses to help with the thickness and weight too. A thicker plastic frame will also help with the edge thickness in terms of aesthetics too

@@precisionopticseyewear thank you sir

Hi, thanks for watching and your question. There is nothing stopping you at all from doing this. Aesthetically, you may notice the edge thickness a bit more (as opposed to a solid colour) depending upon the lenses used etc as you may see the thickness throughout the frame (hard to say without seeing the frame and various other things). The other thing to think about is the edge finish. If you have the edges of the lenses polished then you might have some issue with the internal reflections from the light coming in through the clear frame and polished edge. Your eyewear provider should be able to check all this with you prior to manufacturing. Have you had a transparent frame before? P.s thank you for the Sub too 🙂👍

@@precisionopticseyewear thank you so much for replying, thats so kind of you. yeah my sister uses clear frame but the point is she has a power of -2, and the frame looked good on me so was puzzled rn, and yeah tbh i dont know much but im wearing a frame of solid color black and the thickness is quite visible so i thought the thickness and the whitish glass thing wouldnt be much visible in the clear frame coz they'll look merged or yeah sorry for my bad english. you earned my sub mate ❤

@@Joyboyjr my pleasure. See how you get on. It won't hurt to try a clear frame. Might be worth asking your supplier where you stand with regards with if you changed your mind etc on the frame. I.e if the clear frame also comes in black, maybe if the transparent frames weren't to your liking to pop the lenses into the same model frame in black etc. 🙂

Hi, thanks for watching and commenting. In actual fact, thinner lenses are actually tougher and stronger than a standard index material. The hi index lenses are denser and harder, this is why they are used for rimless eyewear. Hope this helps 🙂

Hi Zee, thanks for watching and commenting. With your type of prescription from what you have said, it sounds like a high + prescription. There are steps to take to get them as thin as possible (all varies depending upon your prescription and measurements etc) Frame choice and shape are important as well as using a thinner lens material (high index). What prescription do you have? As it's a hospital supplied pair, you may find that they are supplying these on the most cost effective way, rather than worrying too much about the style and look/aesthetics of them. Unfortunately in some cases, to achieve a better finish, it will sometimes cost money to get thinner lenses etc. In terms of the magnification that is visible regarding your eyes, I don't think there is much that can be done, as the magnification is just the result of the power that your eyes require from lenses. Many thanks, Colin

Hi, im not sure exactly what the prescription is.. but i can check. Also, so does that mean nothing can be done about the magnification effect? Ive had a couple of friends who have managed to reduce how big their eyes look which made me think that there was a bit of hope. I do like contacts but do they make prescriptions that are that high... I’m just so not used to contacts but i guess i’ll have to force myself to start wearing them

@Zee no problem at all. I'm not aware of anything that can be applied to reduce the magnification other than reducing the prescription which is not want you want or need. I think if you managed to reduce the thickness of your glasses and you felt happier in them, then it may make you feel a bit better in them. Reducing how big the lenses (frame size) is may help with the way things look too.

Hi, thanks for watching and commenting 🙂 Look into a 1.74 index lens material. This material is one of the thinnest and flattest lenses available, other techniques can be applied to this type of lens too, ask your optician for hi index 1.74 lenses and also look for a small round frame shape and size to help reduce the edge thickness and overall weight of the lenses. Hope this helps, let me know if you want any more information 🙂Colin

@@precisionopticseyewear may you send me some image of this kind of frame?

@@user-on5rt3gr9o a frame similar to the Superdry frame you see here in the video is a good idea of the right shape. You can email or get in touch with the ways in the description if you want me to direct message you via email etc. Hope this helps 🙂

@@precisionopticseyewear my email - khalek376@gmail.com

@@user-on5rt3gr9o much appreciated. I will email you 🙂

Hi, technically yes, the less lens at the periphery of the lens will mean the less chance of your eyes picking up distortion, as with high prescriptions, the eye has the best vision when looking through the optical centre of the lens. By having a smaller lens, I would imagine you would notice less distortion. The frame shape and dimensions noted can't really be used as it's all relevant to your measurements too such as your head width and pupillary distance. Hope this helps Colin

@@precisionopticseyewear thanks alot for responding. I'm planning to get this frame it's the smallest I can find which looks good will it be able to lower distortion ?also can u please tell what's the size of the frame of round glass shown in the video? www.titaneyeplus.com/black-oval-rimmed-eyeglasses-from-fastrack-ft1127mfp1.html

@@schandanui yes, the shape looks nice, it's not too square. The main thing is that the size of the frame is relevant to your measurements and that you also use a thinner lens material such as a hi index lens like a 1.74 index material. This will also give you UV protection as standard (double check with your provider)

@@precisionopticseyewear Hi, I'm planning to buy zeiss 1.67 index because I'm already using same on my -7.5 glass and I'm totally satisfied with quality and it's very comfortable. Does 1.74 makes huge difference? It's 2x the price of 1.67 and I can't afford that much :/

Your supplier should be able to run a preliminary test on an order based on 1.67 vs 1.74 to give you your answer, the results are dependent upon many factors. See what the differences are and then work out if the price increases warrants it, personally x2 price increase sounds a bit high to me, regardless of the 1.67 buy that's just my pricing and supply set up etc. Get then to check for you the thicknesses

Thanks for watching and commenting, go for rounded corners, circular lens shape. Try to pick a round frame that isn't too wide as even a round frame can be thick too if it's too oversized. Smaller and rounder. What's your prescription and what kind of frame do you wear at the moment? Thanks, Colin

Precision Optics Eyewear I’m -16 should I get a rounder frame? Ty

Hi @@mayrarico769 , thanks for watching and for commenting. Most definitely, a rounder frame will help reduce edge thickness, rounder and smaller in shape will be best. You can also go for a thinner material such as a 1.74 index lens to help with the thickness and weight also (1.74 is the type and index of the material). There are other materials and processes available, but it will depend upon your eyewear provider with what is doable. Please subscribe to the channel as I will be covering this topic more in depth and it will be worth watching 🙂🤓😎 let me know if you need anything. Kind regards, Colin. Precision Optics Eyewear

Precision Optics Eyewear thank you! 🙏🏼

@@mayrarico769 your welcome, have a great weekend 😎 let me know if you need any more advice and I'll be happy to help. Many thanks, Colin

Thanks for stopping by! What style of frame do you wear? Colin 🙂

@@precisionopticseyewear nerd type thick square frame

@@PasanArunajith great use of the thinner lenses. I'm sure that makes lots of difference 🙂

Just think how much heavier the larger frame and glass would of been if you think the ones you bought are heavy, be thankful that glass is no longer used, that was heavy, The old single vision glasses I have with glass lenses weigh 52 grams my present glasses which are varifocals weigh 25 grams

The gains and benefits depend upon the exact prescription and also frame choice. When you go down the double aspheric route, lenses become thinner and flatter, resulting in thinner and lighter lenses. Some prescriptions may not require this level of thinning. It really depends on the prescription really. Hope this helps. Thanks for your question

@@precisionopticseyewear which would be the thinnest lens choice for -4.00 with a -0.25 cyl

Thanks for your message. Your type of prescription will mean the lenses are very flat on the front, you need to make sure you do not pick a curved frame, as when the lenses are fitted it will make the sides and arms become a wider fit, meaning quite a bit of adjustment will be needed. When you are in the store, ask whoever's dispensing your new glasses, to pick a frame with a close or same match frame PD as your PD, and go for rounder, softer shapes. This will help with edge thickness of the lenses and the weight. You should also consider thinner lenses, something like a 1.6 or a 1.67 hi index with an antiglare coating. You could go for the highest level thinning which is a 1.74, but unless the prescription is high/thick, the difference between the 1.67 and 1.74 are sometimes negligible. Hope this helps 🤓👍

Thanks for watching. The lens you need is called a "hi index lens" it has number values. 1.5 is standard thickness lenses. Then you have 1.59, then 1.6, then 1.67, then 1.74, then 1.76. There are others but as the numbers go up the lens becomes thinner. I hope this makes a bit more sense. Let me know if you need more information. Dont forget to subscribe for more information too that will help you out. Thank you.

@@precisionopticseyewear thanks for the explanation

No problem at all. Even with the difference in languages, this topic is actually quite complex. Thanks again 🤓 Colin

Hi, thanks for your comment. It's a shame to hear that you are not satisfied with your lenses from your supplier. What areas seem to be a problem? Is it the thickness and weight of the lenses?

Hi, thanks for your question. What type of lenses are you going to have? Single vision, bifocals or varifocals?

@@precisionopticseyewear Single vision.

Thank you. We'll depending on your frame and what you are used to, this will be something to take into account. Your kind of at the between part of using a 1.67 or a 1.74 lens. 1.74 is generally thinner for much higher prescriptions, with your prescription you may get away fine with a 1.67. Your supplier should be able to run some preliminary checks to see which kebs type will give you the best thinning. At this point too, you'll be able to see if the extra money for a 1.74 will be worth it. For example, if it was an extra £50 for the 1.74 and you only got an extra 1mm thinner would this be worth the £50? Something to think about. Both materials would most probably come with UV400 protection as standard and normally (not always) come with a combined anti reflective coating and scratch resistant coating. Check with you supplier as not everyone supplies the same spec as standard 👍 What frame type will you have? Full rim metal or plastic? Rimless etc.. Hope this helps

Are you asking for the frames, lenses or both 🙂

Hi Remy, thanks for watching. What specifically did you want an idea of costs on? Many thanks Colin

No need to be scared, this isn't particularly high, don't let this worry you. This has very little reference or reflection on your eye health 🙂 Colin

Hello, thanks for watching and commenting, what do you normally wear or use? Glasses or contact lenses? You could have glasses with -14 lenses, you probably wouldn't have a normal standard lens with this prescription, you would have a specialist lens in a hi index material to help with thickness, also, frame choice is still important with this 🙂
