The adverse effects of sunlight, from melanoma to cataracts, are well known and frequently reported (1). However, because humans evolved under sunlight, it is not surprising that there are many positive effects of light on human health. Light that reaches the human eye has two fundamental biological functions: regulation of the visual cycle and of circadian rhythm. We report here the most recent developments in both of these areas.
