Where I live there are hundreds of optical stores, I have used eyeglasses for a long time and although I visited almost all of them, none of them honestly clarified the difference between the materials. They just told me that polycarbonate was the best material against scratches (which is why I always chose it) when in reality it is not, in addition to putting more emphasis on trying to sell treatments that are not so important. I always trusted their opinion as professionals but the 80% of them (or they employees) only have the mentality of merchants ... it was not until now that I began to learn more thanks to content like this and decide for myself which product is suitable. Thank you very much !
yes for 30 years was told polycarbonate was the best,,so guess was lied to sell more always went for scratch resist and whatever is called so people looking at you can see your eyes not reflections
Yup I can’t believe I kept listening to them. I got glasses with polycarbonate lenses that were recommended for me, and it made my eyes look small and distorted, even got headaches. That was until I did more researched and ordered high index glasses from Ray-Ban to accommodate my higher prescription and it made such a huge difference. My eyes look less distorted, and I don’t get fatigue anymore. I used to hate wearing glasses for this particular reason, now I actually wear them everyday lol
I've been wearing glasses since I was a year old. Since I was a kid, I could see that distortion you talked about on the edges of my strong polycarbonate lenses, but the eye doctor just told me that I must be imagining it, because apparently gaslighting children is acceptable. It's there, and it's why I wear contacts as much as possible.
It's not just kids who get gaslighted regarding lenses. After spending lots of money on lenses and specialists, I finally began my journey to find what was best for me. I know what I'm seeing. I don't allow doctors to tell me that I'm not seeing what I see.
My last pair of glasses had this. The edges were blurry and it seemed like I had a really narrow field of view. I was told that's just normal, but no other pair of glasses I've ever had bothered me that much.
@@astrosquirrel5038 I tried High Index lenses one time and could not wear them. It was as if I had tunnel vision. I could only see clearly out of the very middle of the lens. Couldn't drive with them. After convincing them that I WAS NOT looking through the progressive part, they then told me that some people could not wear them.
I have a question just changed from rectangular lenses to oval and with first time blue light and already have had them for almost two weeks and on the side of the lenses I see blurry and in the front I see perfectly fine. What do you think it might be?
It could be a “base curve” issue. Sometimes going from rectangular frame into that oval can add more curvature to the material. This is something that can be fixed, if your optical shop has control over their lenses (most do). A blue light filter (or most other coatings) have very little effect on your overall quality of vision. Finally if the base material of your lens has changed it could also be that you aren’t adapting. I’ve worked in optical for 2 1/2 years in a specialists office. The only real answer to your question is to talk to your DOCTOR or OPTICIAN. They will be able to give you an actual answer. The things I suggested above are only the cases I typically see.
@@slipknot19968 I have -8 plus 1.5 astigmatism. What do you recommend for lenses? My issue is the high distortion anytime I am moving my eyes. The sides of the lenses are the worst.
@@MiteshDamania your issue could also be material based, or even rx based. Your rx is a little on the high side. Sometimes high myopes don’t like Cyl changes. You’ll definitely have to talk to your doctor and optician, they’ll be able to show you what changes you had since your last visit/purchase.
So much great information in this video. 😊 7:53 Something to be aware of with high index lenses is that, the higher the index the lower the Abbe value, which means you're going to see more chromatic aberration (colour fringing) around the edges of the lenses. Some high index lenses have an Abbe value as low as 31, which isn't great for the clarity of the lens.
I thought something was wrong with my prescription, just turns out they are so high that I get these strong color shifts even in the middle of my vision if the lights are bright enough. Extremely noticeable on my color cycling RGB RAM sticks in my pc, the reds shift physically shift position and make it look like its moving.
@@Nccp9 Unless you have very strong prescriptions and want as thin lenses as possible, go with CR-39 next time. CR-39 has an Abbe number of 59, higher than the eye, so no colour fringing and also a lot cheaper than high index lenses.
@@Nccp9 no you arent! you can get trivex which is a direct competitor of polycarbonate but offers higher abbe numbers and the most clarity while also having the impact resistance of poly! I have astig. and -6, -7 on my eyes so I also have a strong perscription but you are not limited on your options!
Thanks for such an informative video Dr. Allen! I had wondered what Trivex lenses were. Didn't get glasses until age 42, so went straight to Progressives. What could be better than a lens that has every different section allow you to have perfect vision depending on where you're looking? I understand for people who don't start out with them it takes some getting used to. But since they were the first lenses I wore they were a natural for me. Love photochromatic Transitions lenses, as well! The new XtraActive versions are great for people with light sensitivity. They always have the slightest tint and then change tint readily with the strength of the light they're exposed to. Although I have regular transitions as well. I do have non photochromatic lenses for indoors or night time, especially for night driving. 😎
@@cf116 Most won't darken in the car as the car windows block the UV light that causes them to darken. I have a set of clip-on sunglasses that I use in the car instead. Some are designed to work inside of a car but they don't get fully clear.
Great video Doc. I have a -3.25 and -3.5 with -1 of astigmatism in each eye and I just recently received my new glasses with the 1.69 index. Way lighter and thinnner than the polycarbonate ones I used to have! Feels great on the face. Also ordered a slightly lower perscription ( lower by 0.25 in each eye) for computer with Blue Light blocking. I find that computer usage requires less lens power to see clearly than other activities. I then have to switch back when looking for. But at least I don’t mind!
Acetate plastic frame to cover edge of high myopia, 1.67 MC with Transitions but here’s my twist, single vision freeform lens to increase my field of view in the lens to stop the extra astigmatism in the corners of the lenses hehe
I just glasses for the first time last month and I have to admit that I love them so far. I ended up getting polycarbonate lens and I see great with them. It took about two weeks for me to get used to them. I just bought some CR-39 glasses so let’s see how they compare to this one.
Hello, in October I started being through laser sessions due to retinal tears. Soon after I began seeing these bright spots (which later I found out to fit perfectly with the blue field entoptic phenomenon); not to mention an increase in floaters. Any thoughts on what could have caused it? Thanks for the informative content :)
Hey Danilo. Thanks for sharing that. Tough to say why you are seeing the blue field entoptic phenomenon after all that. But very interesting because I see it too. (really want to do a video on that). Floaters are more common after any eye surgery, particularly a retinal surgery. But changes to the vitreous gel and growth of floaters do often cause retinal tears as well.
Great video. Just ordered new glasses after 4 years and I’m so aggregated my prescription increased. I’m 41 and have been wearing glasses since age 6. My right eye is -12 and my left is -11.75. I laughed when you said -2 high. Can you answer what is the highest prescription lenses they make? Also what are the best contacts for high prescriptions and dry eyes? I’d love to try contacts again but the dryness is awful. Thank you.
The highest possible Rx varies by lens manufacturer, lens design, and by material used (almost all lenses are available in multiple different materials). Contact an optical shop for details.
Jenny: Until my cataract surgery, I used to wear contacts, and I had a high prescription like yours. I could only ever wear gas permeable hard contact lenses. With a high prescription the soft lenses they gave me to try once buckled in every time I blinked, and my vision blurred. (The thinner the lenses are in the middle and thicken at the edges the higher your prescription gets.) I assume that is still true today, and that hard contacts are your only option. But if you have dry eyes, you probably will not like contacts. However, at high prescriptions, contacts are usually the only way to see well. You probably also know you are more at risk for retinal tears due to your elongated eye, and when you do eventually need cataract surgery, you may need to get anterior chamber lenses as your zonules will be too weak to hold your artificial lenses in place, and they will slip to the back of your eye (right away or after a number of years if he holds them in place with rings). I'm giving you important information your eye doctor may not know as they don't encounter this so often when doing cataract surgery and may not be used to all the problems this causes. Make sure you do a lot of reading before you make any decisions when you do need cataract surgery.
Hands Down... One of the most genuine and engaging eye doctors on the planet!! I learn something every single video. Thank You, teaching us whenever you can. Truly appreciate you.
Doctor my pupils are dilated when I look at mirror this if for more than 1.5 months I went to ophthalmologist before a month he checked my eye and nerves and said I just have an dry eye and gave dry eye drops for 6 months. So I just have an dry eye but why are my pupils dilated , will dry eye cause pupils to dilated? Please answer fast doctor . I am very depressed for 2 days thinking about this please answer this question. 🙏
Thanks for a very informative video. However, I think you mispoke when you said a -2.00 diopter lens is a high prescription. i always thought that a -2.00 diopter spherical was borderline mild/moderate nearsightedness while a -6.00 or above spherical is a high prescription.
Exactly. I have -3 in my left eye and -2,75 in my right eye, which is right below high nearsightedness and I've bought lenses with higher index, 1,57 but I see very spherically on the edges. I asked a question relating this topic in the comment section and I really hope he'll answer and give me some advice.
You are correct that "high myopia" starts at -6.00 per the classification. But in the video I was just trying to stress when a high index lens would begin to be useful for most people. I appreciate your attention to detail though! It keeps me working harder to be more concise in my future videos. Thanks.
@@DoctorEyeHealth I have been highly myopic with severe astigmatism and strabismus most of my life. It was not until I had cataract surgery at the age of thirty-nine in 1994 that my prescription drastically chsnged Now, my myopia is mild with very little astigmatism in my left and borderline moderate myopia and borderline high astigmatism on my right. My glasses are normal polycarbonate, progressive with transition lenses. As far as my strabismus, I can force my eyes to be straight and deal with the double vision in the distance, but sometimes old habits are hard to break. Anyway, that is why I know about the parameters of what is considered mild, moderate and high myopia. Thanks Doctor for being a stand up guy.
@@aleq.4 I believe aspherical lenses can reduce that warping effect at the edges of the glass. (Thinking about the f-360° eyezen from essilor and similar glasses) Also Index 1,57 is polycarbonate if I recall correctly.
@@samueldisturbing761 Thank you for replying. I' ve mistaken 1,60 with 1,57. I actually ordered 1,60 index lenses, the ones recommend to me. I know aspherical lenses are just for very high myopia, like above -9. I may be wrong, tho
This channel helps alot on people with glasses should gives tips or new thing to know about glasses that is not just a ordinary material Greetings from the philippines
Interesting, but as far as materials you left one out. You can tell me about plastic, but with 50 years of trying all the different lenses, I still like glass. With my high Rx, I do end up with thick and heavy lenses. I also like large lenses that help with my side vison, so the edges have got real thick. I still like the quality and durability of real glass. Takes longer, but it is worth it.
I watched a video on lense coatings that left me with a profound respect for the ultra high lense coating technology. I must admit, I've been careless in handling eyewear and have swore to make changes.
I specialise in glasses from the UK and being in optics for the past 12 years this is what I speak to my patient's on a day to day basis. Very useful video for those new to glasses. My favourite lenses are zeiss or rodenstock. Not a presbyopic just yet!
I've been a polycarb lens wearer for years, and I really like them. I am a big fan of the photochromic lenses, too, since my glasses are always on my face. I've never misplaced my sunnies. :) Thanks for all this information - I've been wearing glasses for almost 40 years and I am always learning from you. I appreciate it!
A very informative video. Incidentally, I just received my very first Trivex lenses and had a little surprise on its "yellowish" color nature, not too sure if this is typical.
I have always used glass lenses; they are readily available at either vision center in my town. Comes at a premium cost, but they last forever. I have relatively stable vision, and the pair that I just moved off from was ten years old. The lenses and titanium frame are still in perfect condition. Now in a bifocal with photochromic glass.
You mentioned that poly carbonate is soft and easy to scratch, but you did not speak of the hardness or scratch-ability of high index or Trivex. at this point scratch resistance is my biggest concern. If the lens is too soft, I believe that compromises any scratch resistant coating as well.
Dr. Allen, I am really hoping you will make a video about "progressive lens options", especially those that are digitally designed. My recent discussions with a number of opticians were about new digital progressive lenses, supposedly superior (and more costly) than earlier ones. They were described as being "top tier" or "premiere" because they are individually designed for a patient's specific prescription, and have a better range of vision levels than older lenses. What are your thoughts about this new technology? Really hoping to hear your perspective before I purchase :-). Thank you.
Hi, recently I got myself a pair of polycarbonate lenses, it has been just like 3 months and I have noticed there are small salt-like, little dots on the lenses, may I ask what are those dots and are they normal? Also, I have also noticed scratches on my new polycarbonate lenses just in 3 months time, while my old cheap plastic glasses took like 1 or 2 years time to see some noticeable scratches... are polycarbonate lenses much more prone to scratches than the plastic glasses?
Polycarbonate is softer than CR-39 "plastic" lenses and will scratch more easily. Don't be fooled by the cheaper price of CR-39, as this polymer has much higher optical quality than polycarbonate and high index lenses. The refractive index and Abbe value of CR-39 are pretty much the same as optical crown glass. Opt. Crown Glass - Index: 1.523 Abbe: 58.5 CR-39 - Index: 1.498 and Abbe: 59.3 Polycarb - Index: 1.586 and Abbe: 30 High Index - Index: 1.6 - 1.74 Abbe: 32 - 42
Really helpful. I have massive chromatic aberration with poly lenses (I have transition and progressives). Lenscrafter gave me poly lenses and I didn't know better until I tried them, and I returned them. My old glasses have Zeiss CR-39 and I had zero issues. I may go back to LC and ask for CR-39 since they have a nice frame I like.
@@windsurfer_LA Thank you. I went back to LC and asked for CR-39 lenses, so now I'm waiting to get them, hopefully they will work, this will be my 6th trip to them (luckily they are very close). I told them about the chromatic aberrations and they kept trying different poly lenses .. obviously didn't work, and I didn't know any better at the time. You'd think *they* would know 😕 Anyway, the information in your videos has been very interesting and helpful - thanks again.
I have an Rx of -9.50 / -11.50 and usually have to get 1.74 hight index lenses. Is there any other lens that is thinner than that? Also to make it more complicated due to age (54) I also have presbyopia (+2.50) for reading. Any recommendations? I was told that I have to have progressive lenses and can not use a bifocal lenses. Is that still the case? Thank you for your great videos. Very instructional and helpful. Thanks again.
I like CR-39, great quality, high Abbe value! I bought a plastic frame and they were sliding off my nose, lucky for me Amazon sells silicone nose pads and they worked, but next time I'll just get the metal frames.
Hi Dr, can you please also elaborate on blue filter coating ? Also digital lens that comes with low addition that claimed can give some sort of ‘relax’ to the eyes ? Thanks for the great info anyway ☺️
Blue light filters improve contrast since the human eye doesn't do too well with blue light. The low addition lens he mentioned is useful for using you smartphone or reading, since you eyes don't need to adjust to the close distance (think of the lens on a camera)
At my Dioptors...-3.75/-4.50.......i always go for 1.74 index lenses as the look amazing in eyeglass frames. Currently sporting Tom Ford specs with Essilor Varilux X lenses 1.74, and Essilor Sapphire coating. I like a streamlined profile so thick specs are a no go!
I have -3 in my left eye and -2.75 in my right eye and I've bought a new pair of glasses with a higher index, 1.57 because on my old glasses, my lenses were a little bit thick. I can't stand at all the new, thinner lenses at all. They are lighter and I love that but I've stopped wearing them because I see very spherically on the lenses' edges and the image of the world seems further, like objects seem smaller and further away from me. Even when I would look at my phone, it appears smaller and 3D 2.0, which means that I see the screen rounder, 3D like. Also, my eyes look smaller, like my prescription would be higher, but is the same as on my old glasses which I'm currently wearing. I just changed the thickness of the lenses. Why is this happening? Is it because I don't need higher index?
Very good question. Typically, I don't hear those types of issues unless the power/base curve of the lens has changed or the vertex distance of the lenses have changed too. I wonder if there is a difference in base curve to the lenses, although the power has been kept the same.
You neglected to mention glass as an option for lenses. I have and still do use glass in my bifocals with photochromatic transition lenses. Because of the environment I work in, they last without scratches and dings. Plus, the transition works in glass better than other materials, unless things have changed in that regard since I last checked. BTW, I have to special order and as far as I can tell there is only one company that still makes prescription glass lenses.
The Industry doesn't really research towards progressive lenses made of glass, so plastic progressive lenses are usually more advanced, but since you are using bifocals that doesn't matter since there isn't a whole lot you can improve on those, aside from progressive lenses. (However some options do exist for glass)
Stange that you say that, we stopped making glass lenses years ago for multiple reasons, one just being safety, and for weight and thickness reasons ( aesthetics ) you should be fine with just a normal hard coat
Hey I have a question does myopia effect the perception of distance? I mean even if I were to wear glasses, does my brain have a poorer perception of distances in general? Or is that mechanism independent to myopia?
HAD to laugh when he said having a high glasses prescription was a -2 lol, I have been -6 for years, but I could always see small stuff, but the last 18 months looking at near stuff with my glasses on has been a blurry mess lol. Will have to see about the progressive lenses
@Chelle Bright I’m just got my new rx of -1.25 (Old Rx was -0.75, -1.25 at my last appointment 6 years ago!) but really feel like I can’t read text or discern faces from very far at all. I know I’m lucky and lots of people have higher prescriptions I just feel more blind than I am I guess.
…but you stopped short of the right hand of the prescription table… what about prisms? What recommendations do you have for those of us with strabismus that are being treated with prisms?
I dont like the polycarb lens I just dont see as clear as I like to. I tried my first pair of Varilux progressive lens and they are a game changer in my opinion. It would be hard for me to be happy now with any other. Vision is so much more clear with varilux but cost is very different between stores.
Varilux lenses come in several different materials, including polycarbonate. You have to compare apples to apples. So polycarb Varilux lenses may not be any better than polycarb lenses you tried.
I don't know yet. I need some help. I have a prescription of -5.75 and -6. I would like a high index lense. The last time I was going to buy metal frames but the lady told me that the lense would look bad because the side were going to look very wide so I just stick with the plastic frame.
HELP PLEASE!! I know is off off topic but i been wearing hard lenses for about 2 weeks .They feel dry and I always feel something in my eye discomfort and dryness ..What can I do pleaseee help!!
Thanks for asking Yazmin! Hard lenses often feel uncomfortable at first. It is something that needs to be worn with more and more time as you adapt to the feeling of the lenses. Eventually, you may not feel them anymore. But I do encourage you to follow up with your eye doctor as scheduled (or sooner if experiencing pain/redness).
@@DoctorEyeHealth thanks so much I have follow your advice and bought Blink for dry eye!! seens to relieve some pain thankyou so much you are a blessing
I have a question. I have astigmatism and require glasses all day long. Since I'm a student I would be spending a lot of time on my phone and computer and I have notes I have began to squint when I try to read. Is it possible to combine both astigmatism and computer lenses. Is it practical?
I got the cheapest lenses to save money and with my left eye being -5.75 and my right eye being -6.25 with an astigmatism of 180 in both eyes. I really should go with high index, and that’s what I’m going todo when I need a new prescription
High index are expensive and if you have a high prescription you will benefit tremendously from a lighter and more responsive lens. The extra cost in that case is definitely worth it. If you have a low prescription like most people have, you won’t see any appreciable difference from a standard lens.
Hey doctor! I recently bought blue light filtered glasses which have a slight yellow tint in them. As I'm myopic (-1.50) in both eyes, can I wear them all day?
Yes the yellow tint absorbs some 20% (speaking about blue light filtering not blocking) of the blue wavelength to help with screen time, but you probably will see improvements while driving in bad weather conditions too. (It's not harmful for the eye)
I'm so excited.

I just found your channel and not sure you talk about it but I don’t seem to be able to find glasses I can see anymore. I tried once progressive glasses but I couldn’t drive (I felt I couldn’t see) and if I had to look far I needed to lower my chin so much it was uncomfortable. I ended up going for two pairs of glasses. Now my shortsidedness has decreased but I have more astigmatism and my optician gave me two pairs of glasses I can’t see well with. Is it my eyesight too sensitive or should I change optician? How do you choose what kind of glasses is better for you? She didn’t ask much about what I needed them for.
I am confused. It says that Polycarbonate material already have a scratch resistant coating when you show the chart of the different kinds of lens. So do we have to ask for this like you mention? It shows the opposite on the chart you put up.
I’m an optician from Germany and as far as I know a hardening coat and a anti-reflective is already a standard on the glass. You could also get lenses with out it but I wouldn’t recommend that.🤷♀️
I don't know if I should just get the single one (just myopia) or the prescription with the "+" also (+2.25, which is the "progessive" lens), online? I heard the progressive lens are hard to get used to, as I have always have just get the myopia lens prescription eyeglasses.
In optics, chromatic aberration (CA), also called chromatic distortion and spherochromatism, is a failure of a lens to focus all colors to the same point.[1] It is caused by dispersion: the refractive index of the lens elements varies with the wavelength of light. The refractive index of most transparent materials decreases with increasing wavelength.[2] Since the focal length of a lens depends on the refractive index, this variation in refractive index affects focusing.[3] Chromatic aberration manifests itself as "fringes" of color along boundaries that separate dark and bright parts of the image. See Wikipedia
Really good question! The only other thing other than high reflections and more chromatic aberration is the lenses are more brittle and may be more prone to chipping if they are hit hard.
@@samueldisturbing761 the lens is a different material in high indexing, maybe the coating is more difficult to attach to the lens? For reading glasses the color dispersion requirements are a low index hence reading glasses are thicker, and heavier.
I enjoyed the way you explained the lens, I sell glasses everyday and know a lot of about theses lens already except trivex lens, we don’t sell those in my store but now I can explain the difference between those and polycarbonate lens better. I also never knew polycarbonate lens have color distortion on the sides I have glasses with poly and hi index lens and the main difference far as seeing is hi index gives a immediate clearer view.
I’m diabetic. Sometimes in the mornings or at night my visón is great without my eyeglasses on. Would you recommend having an eye exam twice,once during a great vision day & one on a bad day? I’ve had lenses years ago on a good day and on a bad day,they were almost useless or were. Ugh. Danke
Hi Love your channel & you - question I watched all your dry eyes videos - just got my new glasses - i have sticky eyes in morning and mostly dry eye (left) with some green gunk. do baby wipes hurt? Drops you would recommend? I sleep with alot of fans on at night - thanks
I have a ton of chromatic aberration issues with lenses that Aren't plastic. My prescription is getting pretty high and the lenses thick. Have there been any advances with aberration value comparable to plastic?
I am so thankful for your videos. I wish you were my eye dr! I am having to educate myself because I am tired of settling for whatever the eye dr has on hand atm. Also, I would like to save money. So, in order to do that I am trying to order online. I have a lot of questions. Thankfully, you have a lot of videos. I feel that you are very honest, knowledgeable, & trustworthy. So glad I found you!
Thank you for those kind words. I'm so glad you've found these helpful! A glasses series has been a long time in the making. I'm glad to be getting this information out there for people.
My Dr. Office said my PD was 53.0 so when. I order online it says that is unusual and either cant get glasses on that certain site or like zenni charges me extra? Is a pd of 53really that unusual? I'd never been told that before.
I need hi index lens due to my prescription however I think it's time for lens manufacturers to get something thinner so I could wear metal frames and semi rimless also
Hi so I just got contacts, and the solution it came with burns my eyes it's the Bosch and Lomb biotrue solution, do you have any recommendations that won't burn when putting them in.
So I'm a photographer by trade. I shoot during the day and edit images at night. Of course I'm also driving to locations which require address location which I use a GPS for. I can see distances during the day but have some trouble seeing at night. I've been using generic reading glasses for basic tasks but prescription glasses for photo editing at the computer. My viewing distance from the monitor is 40". These prescriptions no longer work and need a new set. Not only that but I can no longer see the LCD screen of my camera so I'm constantly lowering and raising my reading glasses to interact with my camera. I'm thinking perhaps I'm a candidate for progressives and given that I'm working on visually demanding projects I would need the lowest distortion lenses. I also may need two sets, prescription sunglasses and one for indoor use.
Your videos are so helpful. Im looking to buy prescription glasses online and have been a bit overwhelmed with all the minute (though major) things to understand...I lowkey wish Id studied to be an optometrist now lol...Thank you
My doctor of 42 years passed away and his wife closed the office and only gave 2 weeks to get our files. I did not even know he had passed and lost 4 decades of info. I need to know what to look for in new doctor and what is the best/most advanced way to get prescriptions.
You will never be getting trivex since it’s something close to 1.6 tho! Also, depending on your lens manufacturer, you should be able to get more than enough tints for your sunglasses. I don’t know which brand are available in your country, but big names such as Essilor, Seiko, Rodenstock, Zeiss.. should be able to provide you anything
@@Tr4dY Trivex is 1.53 index, although it is fairly light for its thickness, and it has excellent optical qualities (freedom from chromatic aberration).
I had polycarbonate previously and just got glass lenses recently. They are slightly heavier... not bad though. They are the winner win it comes to clarity, scratch resistant. What do you think? I mean Im not getting hit in the face everyday so dont really have to worry about shatter lol
whats the best way to get hinner lenses when you have a +11 prescription with astigmatism anything higher than 1.74 on zenni? tired of people looking at my googly eyes or my glasses thickness
Thank you so much for making this video, it was amazing,got to learn so much, it's a request can you make a similar video about contact lenses,I have a left lazy eye, wearing glasses from childhood now I want to try contact lenses, it would be great help, if you could give some guidance, I have +4.50 power in left lazy eye and +2.50 in right eye, would you advise me try contact lenses? Again thank you so much 🙏🇮🇳
Recently I got a new Rx progressive glasses & compared to my previous one, the new one gives me blurred peripheral vision. What should I do ? Thanks HARIBOL
Different lens designs have provide different levels of performance in the various areas of the lens, such as straight ahead vs peripheral vision. These are typically trade-offs that need to be made by the manufacturer. If you are not happy with your new lenses, I would go back to where you got them and demand a refund, remake, or a different lens design. Almost all progressive lens manufacturers offer a 30 day satisfaction guarantee, which is one reason they are so expensive. Make sure you are talking to a person in the store who is an expert in progressives, and the older the better.
Firstly, thank you! Great video. :) I have a concern/question. I just ordered eyeglasses from the local shop and I thought I was getting varilux x series. I'm looking at my receipt and I'm worried bc I see that I have the physio w3+. Are these still going to be good? I don't have a very high prescription, but I'm just sad that the quality of these won't be very good.
Can someone help me how to explain this computer glasses at optic store? The store only know about anti uv glasses for computer. Idk how to tell them tht i need this kind of glasses bcz my eye muscle are sore n not bcos of uv
Glass of course. They’re easy to clean and to maintain and the visual quality is the best. Expect a longer wait time for them to be made because they’re not the default choice these days.
