Ultraviolet
radiation can cause serious damage to the eyes. Edge® Tactical Eyewear lenses
filter dangerous UVA, UVB, and UVC rays for optimal safety.
UVA (315-380 nm)
Although UVA rays are the least intense, they account for more than 90%
of UV radiation reaching the earth and remain constant throughout the
year. Exposure to high levels of this light without proper lens
filtration may cause damage to all layers of the cornea.
UVB (280-315 nm)
UVB rays are the main cause of sunburn and are strongest in the summer.
Permanent retina or lens damage can result from exposure to high levels
of this light without proper lens filtration.
UVC (180 -280 nm)
The most harmful type of ultraviolet radiation comes from UVC rays. The
ozone layer keeps most of the sun’s UVC radiation from reaching the
earth, but some man-made UV sources, such as welders and cutting
torches, do emit these hazardous rays. Exposure to high levels of this
light without proper eye protection may result in photokeratitis, often
referred to as “welder’s flash.”
All Edge® Tactical Eyewear
lenses contain light-reflecting compounds that scatter UV waves. This
blocks 99.9% of ultraviolet radiation, which is the highest level of
protection on the market.
