Abstract

A large body of knowledge exists on the adverse effects of intense infrared radiant energy upon the eye. Infrared heat cataracts were common in industry at the turn of the century, but are now rare. Epidemiological and animal studies permitted the establishment of occupational exposure limits to infrared radiation. More recently, infrared laser bioeffects studies have permitted an understanding of both single-pulse and repetitive-pulse infrared laser injury to the cornea. From a knowledge of penetration depth at different laser wavelengths, one should be able to predict the adverse effects of higher frequency pulsed microwaves upon the eye. These predictions are compared with published data of microwave effects upon the cornea.
