||Thermal effect of visible light and infra-red radiation (i.r.-A, i.r.-B and i.r.-C) on the eye: A study of infra-red cataract based on a model
||Aug. 1994, Vol.38, No.4, p.351-359. Illus. 16 ref.
||Exposure to intense optical radiation in the workplace leads to the development of infrared cataracts. To investigate the role of the wavelength of optical radiation in infrared cataract formation, the temperature rise induced in the eye by monochromatic optical radiation (visible light and infrared (i.r.)) was calculated on the basis of a mathematical model. It is shown that, in accordance with Goldmann's theory, when visible light or i.r.-A is incident on the eye, the radiation is absorbed by the iris and converted into heat which is then conducted to the lens, inducing cataracts. When i.r.-B or i.r.-C is incident on the eye, it is adsorbed by the cornea and converted into heat which is then conducted to the lens, inducing cataracts. It is suggested that i.r. cataracts are induced by i.r.-B or i.r.-C in the workplace.
