The best way to prevent ultraviolet rays in the eyes is to wear sunglasses, umbrellas or wide-brimmed hats when going out, avoid staying in direct sunlight for a long time, and reduce going out during the time period when the direct sunlight and ultraviolet rays are strong, and don’t look at the sun with your eyes, and pay special attention to it in the snowy days. Ultraviolet light on the eye is very harmful, light ultraviolet light will cause damage to the cornea’s epithelium, causing corneal punctate epithelial degeneration, exfoliation, resulting in eyelid redness, fear of light, tearing, pain, and in the worst case, direct burns the macula, causing macular hemorrhage, edema, resulting in permanent vision impairment.
