The ambient levels of ultraviolet radiation (UVR) incident upon the eye and skin vary dramatically with latitude, time of day (solar zenith angle), and geometry of exposure [1–10]. The first two factors have been extensively studied for meteorological purposes and to quantify UVR exposures for epidemiological studies of geographical incidence of skin cancer [11–12], but the last factor—geometry of exposure—has often been neglected in studies of chronic eye exposure to sunlight and in related epidemiological studies of skin cancer and cataract. For this reason, measurements of UVR irradiance in the 295–315 nm spectral band were performed in several geographical locations at several elevations with varying ground reflectance factors to provide a better quantitative estimate of UVR exposure in different climates.
