Visible light (400-700 nm), especially blue light, can produce erythema in all skin phototypes and long-lasting changes in skin pigmentation in individuals with darker skin phototypes (SPT IV-VI) when they are exposed to intensities and wavelengths similar to those from natural sun exposure. [1][2][3][4][5] In addition to the sun, electronic screens also emit blue light; however, they emit these wavelengths at much lower intensities-approximately three orders of magnitude lower than the corresponding intensities in sunlight. Notably, there
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
