Light exposure refers to the reception of electromagnetic radiation within the visible spectrum by an organism, most notably through the eyes or skin. In biology and medicine, ocular light exposure plays a critical role in regulating human circadian rhythms, sleep patterns, and mood by stimulating the suprachiasmatic nucleus in the brain. It is also a key variable in photography, where it determines the amount of light reaching a photographic sensor or film.
