Glare is undesirable light, which has been reflected from horizontal surfaces such as water, sand, snow or road surfaces. Only polarized sunglass lenses selectively eliminate glare.

Sunglass polarizers have an advanced multi-layer construction. The middle layer consists of a polarizer that is unsurpassed in polarizing efficiency. Then dyes are added to other layers for lower transmission and color. Outer layers contain abrasion resistant coatings. Sunglass polarizers provide enhanced eye protection as well as a fashionable appearance.
