Description

4.7.1 General Effects of Radiation on the eye

UV radiation is classified as
UV-A
UV-B (280-315nm)
UV-C (200-280nm)

Potential hazards from UV radiation are photokeratitis, conjunctivitis
and lenticular cataracts (Elliot et.al - see reference below).

Parrish JA, Anderson RR, Urbach F, Pitts D. "UV-A Biological effects of
ultraviolet radiation with emphasis on human responses to longwave
ultraviolet", New York, Plenum, 1978

- UV radiation less than 320nm causes photokeratitis
and conjunctivitis
- large doses of wavelengths greater than 350nm are required to
induce cataract formation, perhaps of the order of
0.5 to 1.0 MJ/m^2
