I have high prescription, -9.00 and -10.00 in both eyes.
I am wearing 1.74 index lenses now.
I am looking for a impact resistant backup glasses (just in case), with my high prescription, can I go for 1.59 index lenses (Polycarbonate)?
I know it will be thick but how thick it could be?
I plan to go for smaller frame size and full rim plastic frame to hide part of the thickness too.
