How it works

The energy we get from the sun can be separated into the following groups. These are expressed in Nanometers.
Complete Wave Length Spectrum
0-------> Gamma Ray & X Ray	200------> Ultra Violet (A, B & C)		400------> Visible Light		700------> Infrared, Radio & Radar
Ultra Violet Radiation - Light Spectrum
200------> UVC		280------> UVB		320------>400 UVA
"Glasshield" is formulated to reduce both UVB & UVA & UVC Rays.
UVC - This radiation is potentially the most damaging because of its high energy levels. Fortunately, at this time, all UVC is absorbed by oxygen and ozone in the atmosphere and never reaches the earths atmosphere. UVB - Although UVB Radiation has some beneficial effects, including the production of Vitamin D in humans, the harmful effects can be serious, causing sun burns, melanoma and other skin cancers and damage to the eye tissue. UVA - This UV Radiation is responsible for the generation of photochemical smog and is the single most destructive band on fabrics and plastics - resulting in degradation and colour loss.
Please Note - being shaded from the sun's direct light rays provides only partial protection from UV radiation exposure because of high levels of diffuse or reflected UV Radiation.
