High-index eyeglass lenses are the right choice if you want thinner, lighter lenses and eyeglasses that are as attractive and comfortable as possible.

Thinner, lighter high-index lenses are especially recommended if you have a strong eyeglass prescription for nearsightedness, farsightedness or astigmatism. But high-index lenses can make your eyeglasses noticeably slimmer, lighter and more attractive regardless of how strong your prescription is.
