“…Rapid advances in the applications of lasers to military problems, communicattions, medicine, and basic research ( 5 ) have resulted in a need to investigate the biological effects of intense beams of photons, especially the ocular hazards associated with the widespread use of laser sources in laboratories throughout the world. Solon (6), (7) and Zaret (8), (9) have published data concerning both the ocular hazards and the ophthalmological applications (light coagulation) of laser beams. Recently, Goldman et al (10) have studied the effects on skin and various biological specimens.…”
