In recent years the development of cataract as a result of exposure to exotic sources of radiation, such as the atomic bomb, the cyclotron and other linear accelerators, and advanced methods of medical treatment using ionizing rays, has repeatedly been reported and continuously studied. Despite this welter of material, there is an old and well-documented form of cataract which should not be forgotten, namely, lenticular opacities resulting from exposure to heat and light. This is of particular significance because some of the newer cataract-causing agents, such as the atomic bomb, produce ionizing rays in sufficient quantity to cause cataract and also produce enough heat and light to warrant consideration as causative or accessory agents. With that in mind, this paper discusses some of the literature on the production of cataract by heat and light and repeats and extends some of the old experiments demonstrating the method by which those rays
