What is the thinnest glasses lens?

[Noelle]

I have a very strong glasses Rx (-8.00 in both eyes)and i dont want bulky lens sticking out. What is the thinnest glasses lens?

People that have strong glasses diopter ( beyond +/-6.00D) are usually advised to choose ultra-thin glasses lens. As a new kind of optical lens, ultra-thin glasses lens have high refractive index (about 1.74), thus turn out to be thinner and lighter than normal lens for the same high diopter. Resin lens with a reflection index of 1.67 or 1.74 may be suitable for you. Besides, smaller glasses frame can also bring you thinner lens.

Usually, the high-index lenses are the thinnest and lightest glasses lenses, especially the type of high-index 1.67, which is also suitable for people who has strong prescriptions and who wear bifocals. And you had better choose the smaller and rounder frame to fit the glasses. Otherwise, it would improve the thickness of your glasses finally as well as plastic frames.
