Ocular ultraviolet effects from 295 nm to 335 nm in the rabbit eye.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, DHEW (NIOSH) Publication No. 77-130, 1976 Oct; :1-60
Pigmented rabbit eyes are exposed to 6.6 nanometer band-pass ultraviolet radiant energy in 5 nanometer steps from 295 to 320 nanometers and at random intervals above 320. Corneal and lenticular damage is assessed and classified. Corneal threshold radiant exposure rises rapidly from 0.022 joules per square centimeter at 300 nanometers to 10.99 joules per square centimeter at 335 nanometers. Radiant exposure exceeding two times the corenal threshold radiant exposure result in irreversible corneal damage. Lenticular damage is limited to wavebands above 295 nanometers. There is an action spectrum for the lens which begins at 295 nanometers and extends to about 315 nanometers. Permanent lenticular damage occur at radiant exposure levels approximately twice the threshold for lenticular radiant exposure. (Contract No. 099-74-0012)
