Ultraviolet light is an invisible band of electromagnetic radiation just beyond the violet end of the visible spectrum. This band is generally divided into three regions that differ in their effect upon the human body. Ultraviolet light is a natural part of our environment, most commonly found in sunlight. Everyone is exposed to UV sources, natural and/or artificial, on a daily basis.

However, unprotected and prolonged exposure to any form of UV light, including long wave UV, can result in cataracts, and possibly cancer. Even brief exposure can be hazardous if the UV intensity is very high. Thus it is advised that the eyes always be shielded for maximum personal safety. When utilizing medium or short wave ultraviolet, the face and skin should additionally be protected.

Spectroline UV-absorbing eye wear and face wear is specially designed to protect the user against most ultraviolet light sources. The UVS-30 Spectacles and UFVG-50 Goggles provide adequate eye shielding, while the UVF-80 Face Shield protects both the eyes and face from ultraviolet radiation.

The UVG-50 Goggles and UVG-80 Face Shield provide maximum protection from exposure to extended or high intensity UV sources, while the UVS-30 Spectacles are generally recommended for sporadic, lower intensity UV sources. The goggles and face shield both meet ANSI specification Z87.1 for safety eye wear and OSHA standard 1910.133 for eye and face protection.
