LUV-10 UV absorbing spectacles
The LUV-10 spectacles are generally recommended for sporadic, high intensity UV sources The goggles and face shield meet ANSI specification Z87.1 for safety eye wear and OSHA standard 1910.133 for eye and face protection.LUV-10 UV absorbing spectacles contain polycarbonate lenses, UV absorption will be 100 percent.
•Protects Against UV Exposure •Fits Easily Over Regular Eyeglasses •Designed to protect the user against most ultraviolet light sources
Ultraviolet light is an invisible band of electromagnetic radiation just beyond the violet end of the visible spectrum. Although UV exposure is a natural part of our environment, prolonged and unprotected exposure to UV light can result in eye damage.
These clear lens spectacles offer 99.9% protection against ultraviolet radiation, provide optimum viewing contrast and help reduce fatigue. The spectacles are lightweight and fit comfortably on the face, even over prescription glasses. Curved temples and raised nose bridge offer a precise fit. Side Arm Panels offer additional eye protection. The side panels are frosted and brow guard sections reduce glare and reflections. Description

Background
Ultraviolet light is a natural part of our environment, most commonly found in sunlight. It is an invisible band of electromagnetic radiation just beyond the violet end of the visible spectrum. This band is generally divided into short,medium and long wavelength regions that differ in their effects on the human body.
The short wavelength region, also known as far ultraviolet, germicidal or UV-C, extends from 180 to 280nm. Although it has little penetrating power, short wave can cause severe burns to the eyes and skin. The usual artificial sources of this radiation are low pressure, mercury vapor lamps and certain other metal vapor lamps used in UV sterilization, chromatography, mineralogy, EPROM erasing, photochemical reaction, etc.
The medium wavelength region, also known as middle ultraviolet, erythermal or UV-B, extends from 280 to 320nm. It has high penetrating power and can seriously burn the eyes and skin. The usual artificial sources of this radiation are “sun lamps” used for cosmetic or therapeutic purposes and vitamin production.
The long wavelength region, also known as near ultraviolet, black light, Wood’s light or UV-A, extends from 320 to 400nm. Some people are overly sensitive to radiation in this region and may experience “blue haze” interference when viewing sources of long wave UV.
Although everyone is exposed to UV sources natural and/or artificial on a daily basis, unprotected and prolonged exposure to any form of UV light, including long wave UV, can result in cataracts and possibly cancer. Even brief exposures can be hazardous if the intensity is high enough.
