Trivex Clear Lenses
 
Trivex lenses are a relatively new development in the lens world.  Trivex lenses have a 1.53 index which makes them a bit thinner than regular plastic lenses, and a bit thicker than polycarbonate lenses.  The Trivex lens material is lighter than polycarbonate, and also has better visual acuity than polycarbonate, and is also recommended as a safety material similar to polycarbonate.  
 
What is Anti-Reflective AR coating?
Anti-reflective coating (aka, no-glare, AR) is a series of layers that is adhered to the back and front surface of a lens, or just the back of the lens if the lens is polarized. The purpose of no glare coating is to help reduce the amount of reflections on the lens. Consisting of metal oxides, each layer is a thin film that is designed to block a specific wavelength of light. The more layers of film, the more wavelengths that are blocked. AR coating causes the light that reflects from the inner and outer surfaces of each film layer to become equal, thereby canceling each other out.
