While AR provides relief from glare off the back of the lens, there are several featured lenses that reduce or eliminate glare from passing through the lens. These include:
Tinted Lens - The color of the tint determines the parts of the light spectrum that are absorbed by the lenses. Manufacturers use different colors to produce specific results.
Polarized Lens - Polarized filters are most commonly made of a chemical film applied to a transparent plastic or glass surface. The chemical compound used will typically be composed of molecules that naturally align in parallel relation to one another. When applied uniformly to the lens, the molecules create a microscopic filter that absorbs any light matching their alignment
Photochromic Lens - Sunglasses or prescription eyeglasses that darken when exposed to the sun are called photochromic lenses, or sometimes react-to-light lenses.
Mirror Lens - The mirror lenses have a reflective coating applied in a very thin, sparse layer -- so thin that it's called a half-silvered surface. The name half-silvered comes from the fact that the reflective molecules coat the glass so sparsely that only about half the molecules needed to make the glass an opaque mirror are applied.
