I have the 1.67 lenses. My prescription is -10.25 in my left eye and 10.75 in my right. I also have no line bifocals and Transitions lenses. The 1.67 are worth every penny of my high rx fee.
@yoy nono I haven’t actually measured them, but in a plastic frame the lenses as they are tailored for my prescription stick out maybe a quarter inch or so in spots. I’m just delighted that I don’t look like the professor from Futurama.
It's important to consider weight. My prescription is -4.75, plus some astigmatism and I get 1.74 lenses just for my glasses to be lighter. For me it has been totally worth it, but maybe others don't notice much of a difference🤷♀️
Hi Nataly Arciniegas Palacio, thank you for watching. :) Thank you for your input, indeed it is something to be considered as well. Please let us know if you have any questions.
Hello. I'm -4.50, I have normally used 1.60 lenses but now I wanted a large and metallic frame (thin) and I was thinking of choosing the 1.74 index so that my lenses are not so noticeable in this frame. But, the abbe value of the 1.74 lenses is much lower (32) than the abbe value of the 1.60 lenses (41), so I fear having worse visual quality and chromatic aberrations with high index lenses. What do you recommend me? Do you think the difference between these two abbe values will be very noticeable in the vision? Thanks for your video!
Honestly it's not that the lenses will not work because they will and they will look 100x better than standard plastic but the 1.74 will look thinner. It's a personal preference
for clarity's sake, pun intended, higher indexes are more dense SO weight is not a significant factor as it's basically a wash. btw, the industry in western industrialized nations are basically a racket. you can take a vacation to japan where they give you a free optician guided digital exam without appointment and come back in half an hour for fully done glasses w/ standard coatings included... maybe a few days depending on a complex Rx + add-ons. either way, you got a vacation out of it and walked out spending $40-250 near the top vs $450-700. btw, i've seen them have index 1.76 - 1.8 in places.
Hey, i have -4.25 and -4.5, and im self conscious about the edges of the glasses making my face look smaller. Will there be a difference between 1.67 and 1.74 high index lens? Thank you!
Hi, my prescription is the following (myopic and astigmatic): Right eye: Sphere Cyl Axis -3.5 -2 5 Left eye: -4.25 -2.25 10 Would it be better a 1.67 or a 1.74 index lens? Thank you very much for your help
Hi Carlo Pecoraro, thank you for watching. :) That will depend on what kind of frame you have. We usually recommend 1.74. Please get in touch with your optician to be sure. Let us know if you have any additional questions.
@@3dPrintingNederland but the same power will give the same mag right ? yes there will be less curve on high index but it's high index , less curve on high index will make bend as much light as high curve on low index , also if it has different mag how would it give him the same power?
The higher the index lens is, the more blurry and distorted the peripheral vision will be from the view of the person wearing the glasses. So, if you want visual acuity, lower index will provide less distortion and clearer peripheral view.
You choose a lens according to your size, for example, minus 5 is better than 1.67, but minus 3 -3.5 to 4 will be sufficient. Minus 2.5 and less will be 1.56-1.50. Better than minus 7. 1.74 is preferable, but minus 2.5 is better. 9 will be mandatory
Hi @naturelover9791, Thank you for watching. For your prescription, I would recommend the 1.74 index. It offers superior optical clarity and can provide better visual quality for higher prescriptions compared to the 1.67 index. If you need further assistance, please feel free to contact us at +1 866 653 5227 or Email service@rx-safety.com
I am 5 and 4 with a deviation of one, a quarter, and a half degrees. I chose 1.67 based on the recommendation of a seller whom I trust + previously I used 1.60 + 1.67, which is very thin for my size. It is ideal to minus 6, but from. 7 1.74 would be reasonable and not a waste of money
Hi Sujata, 1.59 is a recommended lens index but we always recommend our customers to confirm this with their eye doctor, they are the experts and best one to tell you what lens index should be the most recommended depending on your prescription.
Hi there! Yes, I would go with the 1.67 for that prescription. For more information, you can visit this link: www.rx-safety.com/product-category/high-index-glasses/
my eye prescription is -9 i was recommended for 167 is that okay? i haven't worn prescription glasses for 8 yrs i'm afraid i would look like awful. since i work in a hotel i cannot wear thick glasses. since i have to rest my eyes i need glasses for awhile.
Bring your prescription to a person who is willing to calculate the lens thickness by measuring your chosen frame dimensions and your pupil positions in the frame. Your being near-sighted means you are very capable of looking at the result measurements at very close range.
Hi Kristen Cortes, thank you for watching. :) Yes, you can get 1.67 high-index lenses with your prescription. Please let us know if you have any additional questions.
looked to see if anyone has my #'s but no so, my prescription is +2.25-2.25 x 090/ +2.50-2.50 083.....add +2.00. I want blue IQ reading /computer glasses and another pair polarized sun/work glasses. I'm looking at all the options offered 1.5/1.53/1.6/1.67/1.74. The sight recommends 1.74. Does it matter? can it be 1.5 even? ty, Oh and i usually get the shortest/narrowest rectangular frames for reading, but larger/est aviator's for sun/work.
Hi Nikhila Peddada, thank you for watching. With both lenses you will get lighter, thinner lenses with superior clarity. For more information about them, check out our blog post about the subject here: rx-safety.com/2020/07/the-difference-between-1-67-and-1-74-high-index-lenses-and-whether-its-worth-it/. However, we recommend you to get your optician's opinion to know which lens material will be the best fit for you. Please let us know if you have any other questions.
i have -5,5, what lens should i buy 1,56 or 1,61 or 167? 1,56 are 5 bucks, 1,61 22 dollars, and 1,67 33 dolars... I'm thiniking about 1,61 would that be ok?
You can see some frames we suggest for people with high prescription that work well with 1.67 and 1.74 lenses rx-safety.com/product-category/high-index-glasses/
You can get edge polish for $25 at Pearle Vision and probably other stores that makes the edges clear instead of white. Actually they told me at 1.74 it is included there.
Hello Zoura, you can choose from a variety of styles on our website. When you choose " Buy frame with prescription" it will take you to the page where you can add the lens options and next enter the values of your prescription. Please follow this link: rx-safety.com/product-category/sunglasses/
Is it weird that my new glasses with 1.74 lens is popping out on the side whereas my old glasses with 1.67 did not? They are same prescription and similar frame size/design. Maybe new one is 2mm larger in lens height and width.
@Mike Studmuffin are you implying that the side thickness of the lens will depend on frames shape? If so, would Rectangle, Square, Geometric or what shape would be best so the curvature won't be so obvious? My right eye -12.25 left eye -7.75 1.74 isn't great with my rectangle glasses
@@silver831cali3 hi! Yes, the larger the lenses of the frame you want for your glasses are, the thicker your glasses will be. In general, if you want to avoid overly thick glasses you should go for the smaller glass frames, even if high index glasses can also help to shave off quite a bit of the thickness as well. Also, in general rounder lenses will work better with higher prescriptions. Hope I could help 😀
