Photokeratitis is known by a number of different terms, including snow blindness, arc eye, welder's flash, sand eyes, bake eyes, corneal flash burns, flash burns, niphablepsia, or keratoconjunctivitis photoelectrica.
Symptoms are redness and swelling of the eyes. Most often the condition is caused by prolonged exposure to Klieg lights , therapeutic lamps or acetylene torches. Other names for the condition include Klieg conjunctivitis, eyeburn, arc-flash, welder's conjunctivitis, flash keratoconjunctivitis, actinic ray ophthalmia, X-ray ophthalmia and ...
Flash blindness is an either temporary or permanent visual impairment during and following exposure of a varying length of time to a light flash of extremely high intensity, such as a nuclear explosion, flash photograph, lightning strike, or extremely bright light, i.e. a searchlight, laser pointer, landing lights or ultraviolet light.

“When systemic and chronic inflammation accompanies these underlying diseases, it can affect multiple organ systems, manifesting as fatigue, muscle weakness, digestive disturbances, joint pain ...
Floaters drift around your field of vision and dart away when you try to look at them directly, eventually settling at the bottom of your eye and out of your sightline. Floaters appear when the ...
Flash burn. Flash burns are caused by electrical arcs that pass over the skin. The intense heat and light of an arc flash can cause severe burns in a fraction of a second. Although the burns can cover a large area of skin, they are largely superficial and the tissues beneath the skin are generally undamaged and unaffected.
This is most commonly the result of exposure to the sun at high altitude, and in areas where shorter wavelengths are readily reflected from bright surfaces, such as snow, water, and sand. UV generated by a welding arc can similarly cause damage to the cornea, known as "arc eye" or welding flash burn, a form of photokeratitis. [52]
This includes penetrating globe injuries; corneal abrasions or corneal foreign bodies; hyphema (must be referred); eyelid lacerations that are deep, involve the lid margin or involve the lacrimal canaliculi; radiant energy burns such as arc eye (welder's burn) or snow blindness; or, rarely, traumatic optic neuropathy.
