Photo Keratitis
The human eye is protected by a transparent tissue called the cornea. It is a naturally structured barrier that safeguards the eyes from infections caused by environmental pollutants, smoke, ultraviolet rays (UV rays), and many others. Photo keratitis is a condition whereby the eye experiences stinging and burning pain inside and on the surface of the cornea. In addition, the eyes turn reddish, and the eyelids become dry and swollen. It happens when the eye is directly exposed to UV light (mainly from the sun’s glare) or intense sunlight reflected into the eyes from ice, sand, snow, and many others. Other UV light sources include lamps, arc welding tools and equipment, lasers, and electric lights.
Although Photokeratitis is temporary and only lasts up to 2 or 3 days. The symptoms go away, but direct and long-term exposure to these UV lights may permanently damage the eyes. Some examples are cataracts, macular degeneration (blurs and affects central vision and eye discoloration), other eye conditions, and blindness if no immediate action is taken.
If the eyes start to hurt from exposure to UV lights, avoid staring at the sun or any bright light and use eye protection.
