Polycarbonate Polarized RX ( Gray / Brown )
 
Polycarbonate lens material is the best choice for children, active adults, and sporting activities. Polycarbonate lenses are virtually shatterproof, provide the best eye protection of any lens, and includes 100% UV protection inherently. If the sphere on your prescription is +/-3.00 or higher, you should choose polycarbonate lenses. Polycarbonate lenses are very difficult lenses to tint and are not recommended for people who want custom dark sunglass lenses (we suggest Trivex lenses in this case). The suggested prescription range for polycarbonate lenses is plano (0, no Rx) to +/-6.00 sphere.
 
How Do Polarized Lenses Work?
Light travels in waves, and the waves of normal light travel in several different directions. Combined, they create the visible light we see, whether it comes from the sun, a lamp, or a candle. But when light is reflected off of a flat surface or a body of water, it travels in only a single direction. This gives the reflected light an uncomfortable intensity that we call glare.
Normal sunglasses work by limiting the amount of light coming from all directions, dimming it so that you find it easier to look around without squinting. Polarized lenses go a step further, taking advantage of the fact that most reflected light travels in only one direction. Using a special chemical process that creates a special coating on the surface of the lens, these glasses filter out all light coming from that direction, virtually eliminating glare.
