The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity. [ 1] It usually occurs due to staring at the Sun ...
Photokeratitis or ultraviolet keratitis is a painful eye condition caused by exposure of insufficiently protected eyes to the ultraviolet (UV) rays from either natural (e.g. intense direct or reflected sunlight) or artificial (e.g. the electric arc during welding) sources. Photokeratitis is akin to a sunburn of the cornea and conjunctiva.
Short-term over-exposure can cause snow blindness, which is analogous to sunburn of the cornea, or can cause solar retinopathy, which is long-lasting retinal damage and vision impairment from sungazing. Frequent exposure to the sun can cause yellow non-cancerous bumps on the middle part of the sclera of the eye, called pingueculae. It is most ...
Sun damage can show up in different ways, and it can be acute — meaning, you see the damage right away — or chronic, meaning it develops after prolonged exposure to UV rays. An obvious acute ...

Alternative diagnoses. v. t. e. Sungazing is the unsafe practice of looking directly at the Sun. It is sometimes done as part of a spiritual or religious practice, most often near dawn or dusk. [ 1] The human eye is very sensitive, and exposure to direct sunlight can lead to solar retinopathy, pterygium, [ 2] cataracts, [ 3] and potentially ...
A UV index reading of 8 to 10 means very high risk of harm from unprotected sun exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly. Minimize sun exposure between 10 a.m. and 4 p.m. If outdoors, seek shade and wear sun-protective clothing, a wide-brimmed hat, and UV-blocking sunglasses.
