W89: Exposure to man-made visible and ultraviolet light

Exposure to man-made visible and ultraviolet light refers to a group of conditions caused by overexposure to artificial sources of light, such as tanning beds, fluorescent lamps, or certain types of laser light. These conditions can occur when the body's protective mechanisms against light damage are overwhelmed, leading to harmful effects on the skin and eyes primarily. Symptoms can vary, starting from mild conditions like suntan, sunburn, or temporary visual disturbances, to severe conditions like skin cancers or permanent vision loss. The severity and progression of the conditions depend on the intensity and duration of the light exposure, and individual sensitivity. While some people may experience immediate symptoms, in others, the effects may develop gradually over time, often due to unnoticed or neglected overexposure.
