Ray Ban Sunglass Lenses: Guaranteeing Optimum Visual Quality

Aesthetically speaking, Ray Ban sunglasses are probably among the best in the world. Celebrities are regularly seen wearing them: movie stars, athletes, musicians. Ray Ban sunglass lenses contribute significantly to the appeal. The color of the lenses does not fade over time even after constant exposure to sunlight because of the chemical oxides that are placed into the base mixture that is to become the lenses during manufacture.

Another excellent quality of the lenses of Ray Ban sunglasses is their durability. They are made of the highest optical quality materials, which are processed chemically to create something called a compression stress layer. This layer makes the lenses extra tough. Moreover, the lenses are subjected to the most stringent tests to ensure their strength and endurance. In fact, these tests show that the lenses are able to withstand the impact of a 5/8-inch ball dropped on them from a height of 50 inches. These tests are required by the U.S. Food and Drug Administration (FDA) and the American National Standards Institute (ANSI) for the quality control of lenses.

The lenses of Ray Ban sunglasses provide the wearer with one of the most important things that good eyeshades should provide: total protection from ultraviolet radiation. UV rays are deceptively dangerous; they are very potent even on cloudy days. They can cause a host of eye diseases, including photokeratitis (corneal sunburn), cataracts, macular degeneration, and eye cancer. Aside from filtering UV rays, Ray Ban lenses also guard against potentially harmful infrared rays.

Ray Ban sunglass lenses come in a variety of shapes and colors. There are also models that have polarized lenses, which come in handy for reducing glare that can reflect off surfaces such as pavement, water, and snow. Some Ray Ban sunglass lenses are photochromatic; they become dark in bright sunlight or become translucent in areas with less light. Whichever style or model catches any individual’s fancy, he or she can rest assured that they will be getting a high-quality product – something that may be more than their money’s worth.
