Under the effects of excessive and deficient light the following affections are described: eclipse-blindness, night- blindness, erythropsia, snow-blindness, and miners' nystag- mus. Electrical injuries proceed either from lightning or industrial electricity. The effects on the tissues of the eye from exposure to x-rays and radium are also described under this heading.
