The electronic computer is often said that the computer has in our country become more and more popular, people say that in this day and age do not like a computer is not literate, become the standard of illiteracy. Thus, the computer has in our lives, work plays a more and more important status.

However, with the popularity of computer, and computer related hazards is more and more frequently appear in the media reports, long-term use of computers to the body will have a lot of harm, the most serious Mo too computer radiation harm.

Computer radiation is generally considered to influence the body, the most important is the effect of the user's eyes, resulting in ophthalmic diseases, aiming at the problem of radiation, in order to protect the eyes, people study the optical anti radiation glass lenses, wear after use can weaken the radiation harm to the eye injuries, health protection. Today we are going to simple research about optical glass radiation problem.

Radiation resistant optical glass have been introduced in the CeO2 in high energy gamma ray irradiation, electron capture, do not make internal glass color center and because of CE and CE absorption bands in the UV region. When CeO2 content is too high, in the ultraviolet and infrared absorption band extends to the visible region, to increase the absorption of visible light in the blue region, resulting in glass is yellow. At the same time, also because of the influence of other components of glass to deepen the color, so CeO2 content can not be too high, in the CeO2 content of K509 is about 0.4% ~ 0.5%, K709 in the CeO2 is about 1%.
