Paper Abstract

Ucular damage resulting from exposure to intense light, has been a long standing concern--with solar eclipse burns, snow blindness, and glass blowers cataracts being examples. The development of intense light sources by man, culminating to date with lasers, has increased the possibility of accidental exposures. Systematic laboratory study of ocular damage was initiated in the early 1950's and has continued more or less continuously ever since. Probably the most thoroughly understood mechanism of injury is that described as thermal. This mechanism has been rather thoroughly modeled and the model validated reasonably well within the limits of its applicability. However, other mechanisms of injury such as acoustical shock waves and photochemical interactions have been identified and have received considerable attention in the past decade. The results of the research efforts of many investigators over a considerable span of time have been incorporated into numerous Laser Safety Standards, typified by the American National Standards Institute Z136.1 Standard for the Safe Use of Lasers. These standards, although carefully conceived and based upon a large body of empirical information are neither complete nor final and should be updated as additional information is uncovered.
