These Polarized Trivex lenses are a steal at 66% off the market price!
Recommended prescription range for Trivex Lenses: Sphere power below + or - 3.00; Cylinder power below + or - 2.00 Trivex lenses are the new rival for polycarbonate lense; they are thin, lightweight and much more impact-resistant than regular Plastic CR-39 or Polycarbonate lenses. Trivex lenses have crisper optics, and may have sharper central vision than Polycarbonate lenses. They may also have less chromatic aberration then Polycarbonate lenses as well as sharper peripheral vision. The index of refraction is 1.53, making them about 10% thicker than Polycarbonate lenses. Trivex lenses offer 100% protection from UV light, as do Polycarbonate lenses, however, they do need a scratch-resistant coating to prevent scratches. Todays modern coatings can make the surface of these lenses nearly as hard as glass.
These polarized lenses are popular with boaters and fishermen who need to eliminate or reduce reflected glare from the water. Other outdoor enthusiasts have discovered the benefits of polarized lenses, including bikers, skiers, golgers, and joggers. These sunglasses can be used for driving and can even reduce glare from a long, flat surface such as the hood of the car or the surface of the road. Polarized sunglasses may be worn indoors by light-sensitive wearers, including post-cataract surgery patients and those continually exposed to bright light through windows.
