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.
Peripheral (posterior) vitreous detachment occurs when the gel around the eye separates from the retina. This can naturally occur with age. However, if it occurs too rapidly, it can cause photopsia which manifests in flashes and floaters in the vision. Typically, the flashes and floaters go away in a few months.
Photic retinopathy is damage to the eye's retina, particularly the macula, from prolonged exposure to solar radiation or other bright light, e.g., lasers or arc welders.The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity. [1]

Officials are warning of “bleeding eyes” virus, a.k.a. Marburg virus, after deaths in Rwanda. Here doctors share symptoms, treatments, and prevention.
[citation needed] The distance from an arc flash source within which an unprotected person has a 50% chance of receiving a second degree burn is referred to as the "flash protection boundary". The incident energy of 1.2 cal/cm 2 on a bare skin was selected in solving the equation for the arc flash boundary in IEEE 1584 . [ 15 ]
"The potential dangers of using at-home LED masks include headaches, eye strain, sleep disturbances, insomnia and mild visual side effects," she explained. "It’s essential to go to a board ...
