During what condition may photo-keratitis occur?

Photo-keratitis is an inflammation of the cornea caused by exposure to ultraviolet (UV) radiation. This condition often occurs in environments where there is intense UV exposure, such as at high altitudes, near water, or on snowy surfaces, where UV rays can reflect and increase exposure to the eyes.

UV radiation can damage the surface cells of the cornea, resulting in symptoms such as redness, pain, tearing, and a gritty sensation in the eyes. Unlike other conditions that might affect eye health, photo-keratitis is specifically related to the intensity and direct exposure to UV light, making it crucial to wear protective eyewear in these situations to prevent such damage. Understanding the risk factors associated with UV radiation can help in mitigating the risks of this painful condition.
