[Introduction]: Humans in their day-to-day lives are exposed to solar ultraviolet (UV) radiation. These solar UV exposures can be separated into UVB exposures (280nm to 320nm) and UVA exposures (320 to 400nm). Most acute responses of humans to UV exposure occur as a result of UVB exposures, as these wavelengths are highly sensitive in creating a human biological response. This however does not result in UVA radiation not having an impact on human UV exposures and health. UVA can cause erythema in human skin, yet, the exposures required to create such a response is much larger than UVB radiation. UVA radiation penetrates much deeper into human skin tissue than UVB, resulting in impacts that are not as acute, taking many years to manifest. UVA exposures are associated with wrinkling, loss of skin elasticity, ocular disorders and it has been implicated in the development of skin cancers
