What is polarize lens?
Polarized lenses (driver lenses),index1.499
Daylight travels in waves oscillating in all directions of three-dimensional space. Polarized light also travels, but mostly moves in two dimensions: horizontally and vertically. Vertical light brings useful information to the human eye, enabling us to see colors and contrasts, while horizontal light simply creates optical noise or glare. Where light strikes a non-metallic surface such as water it often reflects primarily in a horizontal plane. This creates a high concentration of glare which can be selectively blocked only by a good quality polarizing filter.
For years, boaters and fishermen have used polarized sunglasses to reduce reflected glare from the water surrounding them.
Besides boaters, drivers benefit the most from polarized sunglasses, for polarizing lenses are the best lenses for driving. Polarizing lenses selectively filter out the horizontal light, thus the drivers will enjoy a clearer view along with elimination of glare. Once wearing polaroid sunglasses, the drivers will benifit:
100% UV protection
Significantly less eye-fatigue
Outstanding color perception
Some other outdoor enthusiasts will also benefit from polarized sunglasses such as skiers, bikers, golfers, and joggers. Once you wear polarized sunglasses, you will love them and will never wear other ordinary sunglasses.

Diamond Clear Polycarbonate High Index 1.591
It is required for children, sports, danger zone and any impact environment.
Polycarbonate – Your Choice for Safety Polycarbonate is a unique material that was originally used primarily for industrial safety glasses because of its very high impact resistance qualities. It is now used for children, sports wearers, certain rimless frames, or anyone requesting greater impact resistance in their lenses. These lenses are the same thickness as our standard thin (1.6) lenses. Poly carbonate lenses are a very strong lens type which, as a higher refractive index material are also slightly thinner. All polycarbonate lenses automatically come with ultraviolet protection and we never charge an additional amount for this feature.
