Abstract

Damage to the eye can result from unexpectedly low levels of light, particularly at the shorter wavelengths. UV emitting lasers such as Excimer (248 nm, 308 nm, 351 nm) and HeCd lasers (325 nm, 354 nm) are increasingly used in various applications including: medical, research (spectroscopy), stereolithography and semiconductor industries. Therefore, protection against harmful UV light is needed, but more importantly, development of a material that will react to detect the presence of UV light while completely protecting the wearer, is of great interest. Such materials have been developed with the use of lightweight clear plastics such as acrylics by incorporation of UV reactive photochromic compounds into a polymeric matrix.
