Lenses
Thinner, lighter high-index lenses are especially recommended if you have a strong eyeglass prescription for nearsightedness, farsightedness or astigmatism.
High-Index Lenses
1- Thinner. Because of their ability to bend light more efficiently, high-index lenses for nearsightedness have thinner edges
than lenses with the same prescription power that are made of conventional plastic material.
2- Lighter. Thinner edges require less lens material, which reduces the overall weight of the lenses. Lenses made of
high-index plastic are lighter than the same lenses made in conventional plastic, so they're more comfortable to wear.
