Erythema can arise from exposure to ultraviolet (UV) radiation primarily as a result of sunburn. When the skin is exposed to UV rays, it can cause inflammation and increased blood flow to the surface of the skin, leading to redness and swelling—characteristic symptoms of erythema. This condition can develop after a single intense exposure to UV radiation or after repeated exposures over time.

In contrast, while keratitis and conjunctivitis are eye conditions related to UV exposure, they specifically affect the eye rather than the skin. Keratitis involves inflammation of the cornea, and conjunctivitis involves inflammation of the conjunctiva, which are not directly skin-related. Dermatitis, though it can be caused by various irritants and allergens, is a broader term that encompasses any inflammation of the skin, but does not specifically refer to the effects of UV radiation. Thus, erythema is the most directly associated skin condition resulting from UV exposure.
