great comparison. i have -6.5 rx plus -1.5 astigmatism. i didnt think the 1.74 index would be that much of a difference comapred to 1.6. its definitely worth it.
Very nice video. I have a question for you if the high index glass thickness will differ from shop to shop. Today I got to know about this from Titan+ store, Pune, India that their 1.7 high index glass thickness is more than the local opticians. Please let me know about this. My current glass has 1.57 high index and 50 size frame. thank you.
So, since I have someone that is set on photochromic lenses that is a -5.75 with a -5.25 astigmatism on top of that it's worth getting the 1.67 instead of the 1.61? Thank you

Hi doctor, Please i need your suggestion perviously I had a cylindrical power of -0.50 in both the eyes and axis was 180 in both the eyes, and now recently I got my eyes checked and now the cylindrical power is -1.00 in left eye and -1.25 in the right eye and axis changed to 170⁰ on left eye and 10° on the right and the SPH power is -3.00 and -3.25 respectively. After wearing glasses I feel like the cylindrical power is little bit over powered and i feel eye strain some times should i continue with the glasses or i should get my eyes checked again? Its been 2 days im wearing glasses and should I wait few more days to set my eyes ??
With the new pair of glasses, generally it takes approx 2-3days time to get adaptated . Even after few days , if you feel the same, please visit to them to get it cross checked once.

Sir my power is Right side SPH -6,CYL -3, AXIS 40° Lift side SPH -2, CYL -6, AXIS 150° my glasses very thick I want thin glasses what can do plz suggest me
Ur prescription is on the higher side. Even if you for the high index index lens,there will be thickness showing due to the prescription. While selecting frame u can go for full frame ,so thickness can be covered upto some extent,secondly u can do for smaller diameter frame as it can reduce some extent. But there will be thickness showing since the prescription is on higher side. When you visit Opticals u can ask them to suggest and according u can do.
Is it true that the higher the index lenses are the more distortion there is? I recently got a high index of 1.74, and I find that the peripheral view is blurrier and more distorted than my other pair of glasses with a high-index of 1.60. The prescription on all the glasses are the same.
Hello sir Hope you r sound in body and mind. My sister has myopia and after cycloplegic drop instillation she unable to reach same day,and furthermore cylindrical lens added along with spherical lens.now she has problem in vision .what are the possibilities of this situation.please reply .thanks
1.74 is recommended. But since ur power is -6.00,the edges will be not very thin,but it will be better compared to other index. Secondly u can even think about Contact lens, but for that plz check with any eyecare practitioner if you are eligible for it.
Very nice video.... Is it ok to have differnt index lenses for different eye. For example lens of my left eye is of index 1.56 and lens of right eye has index 1.61.

Sir amar power -14.50 right eye te r around - 10 left eye te. doctor recommended me to use high index xpectacles. Now my question what kind of spectacles should i choose? small or large?
Smaller size frame is recommended, because it will help to reduce the thickness of glass,in comparison to large frame. Also go for high index lens. But then also thickness will be there considering this amount of prescription.
I just watched a video minus16 just picked up my glasses and high index 1.90 seemed this is thicker than I thought would be :( just watched and sadly the thinnest can be and I'm that's the way they are :( always my contact lenses to make me feel better

High index lenses are actually make vision worse. It has lower abbe value and worse definition due to more chromatic aberration. There are no microscopes, binoklis or photo objective made with high index lenses.

For a particular index, the thickness will be same, considering in same frame .

Hi doctor, thanks for the informative video! Could you please suggest the best brand for high index lenses with blue cut, photochromic (-5 power)?
There are lot of good brands.
What about -6.25, do you advise to go with 1.67 or 1.74?
more than 5 is 1.74
1.74 will be more thinner compared to 1.67
I am -9.00 myopic with -0.75 astigmatism in right eye, and -8.25 myopic with -1.50 astigmatism in left eye.
Would there be a big difference in lens thickness between the 1.67 high index and the 1.74 high index?
For this prescription there will be difference. You can ask the store to show the approx difference in the demo chart .
