Over time and with exposure to UV light rays, the natural lens of the eye filters out the vast majority of damaging ultraviolet light before information technology has a chance to damage the retina and macula. The aforementioned is truthful for most artificial cataract lens implants. However, there is some evidence that suggests the retina and macula can become damaged by ultraviolet radiation, resulting in meaning vision loss and conditions such as farsightedness.

Pterygium – Also known as surfer'southward eye, pterygium occurs when the protective membrane of the exterior of the heart called the conjunctiva becomes inflamed and grows out toward the optical center of the eye. It is typically associated with prolonged exposure to sunlight, especially when reflected off the surface of water or snowfall.

Keratitis – Excessive exposure to harmful UV rays from the sun and tanning beds can really cause the cornea to burn, non dissimilar a sunburn. The cornea is used to refract calorie-free inside the heart and directs calorie-free to the retina. Keratitis tin as well be caused past an infection or parasite and results in inflammation of the cornea, which if left untreated may outcome in permanent impairment.

Skin cancers of the eyelid – Every bit with the rest of the body, the eyelids are vulnerable to the harsh effects of UV radiations and can not only exist burned by overexposure, but tin also develop varying degrees of skin cancer, including basal cell carcinoma, squamous prison cell carcinoma, and melanoma.
