Throughout the past few decades, it has been established that people are being damaged by ultraviolet light from the sun, and so we are being encouraged by the medical industry to take protective measures to limit the effect the sun has on our skin and eyes. UV blocking glass is one such way we can protect ourselves from ultraviolet light damage as well as isolating UV light for specific uses.
There are certainly other ways to protect us from low intensity ultraviolet light and new products come out all the time that offer this protection in various ways. Vast amounts of research and effort have been put into finding out just how dangerous UV light damage is and how to prevent it. Lotions, glasses and even clothing have been developed to prevent the carcinogenic effects of UV light exposed to our skin and eyes. These protection are effective when the source of the ultraviolet light is the sun, but what do you do when the sun is not the source?
While the sun is widely recognized as the most significant source of UV light it is not the only source we must work to protect ourselves from. Ultraviolet light is known to emanate from many different man made sources like high pressure arc lamps and fluorescent lamps as well as incandescent lamps and solid state light sources (LED's, OLED's and PLED's). In fact it is known that broadband or "white" light sources are almost guaranteed to produce at least some UV light along with the visible light intended.
