High index or not?

Question

is there is differance in how you see with plastic with ar or high index with ar..would i see the same or would one i would see better?

Answer 1

What is your perscription? High Index is usually used when someone has a high perscription. If glasses are your primary corrective lense, the definately get the Anti-Reflective no matter what material  you have your lenses made out of. You will notice a difference in clarity between the two materials. But if you're not willing to pay for High Index lenses, go for the basic Poly Carbonate over plastic. It's more scratch and shatter resistant.

Answer 2

Poly Carb lenses are not the best choice for optical clarity , and it isn't true that they are more scratch resistant. They are LESS scratch resistant than other lens materials.

Anyway...to your question , it depends on your prescription as to whether high index will benefit you or not.

In general a 1.6 lens is 40% thinner than the regular plastic lens, so less edge thickness means less peripheral distortion.Again it depends on your Rx as to whether you will get better central vision also.

If you wear a minor correction though, the difference won't be noticable.

The optical quality of a 1.6 lens is superior to polycabonate any day.

I also have to wonder why our Optometric tech doesn't know that the word is  PREscription, not PERscription...twice here, and twice in another post.

Answer 3

Since high index costs extra, I only recommend it for those who wear strong prescriptions. It makes the lenses thinner and lighter, which wouldn't matter much for those who wear weaker prescriptions because their lenses already are thinner. I always get high index when I get new glasses because I do wear a strong prescription.
