Ultraviolet radiation (UVR) is the light most frequently linked to health problems. Unfortunately for residents of Planet Earth, more than 95% of this damaging light is not filtered through our atmosphere and reaches the surface. This dangerous range known as UVA (between 315 – 400nm), is responsible for most of the problems associated with sun-exposure because these waves penetrate deeply into the body.
Windows in most homes and offices use tempered glass. Tempered glass blocks only 30% of UV. The latest energy-efficient windows are much better, yet they only attenuate 80%. Most people are unaware that fluorescent lights also emit UV, which has been shown to damage skin cells in laboratory experiments.
Polycarbonate – the most commonly sold lens material – lacks the ability to block UV light. Unless you’re equipped with ZEISS lenses.
ZEISS is leading the industry once again by offering full UV protection on all ZEISS clear plastic lenses, offering the same level of UV protection as their top sun lenses. This is something that no other manufacturer is doing. UV protection will help protect your eyes and eyelids from all UV: inside or outside.
We hope all of our customers recognize the danger of UV and take appropriate precautions to maintain the best health of their skin and eyes.
