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.

This is termed arc eye, while photokeratitis caused by exposure to sunlight reflected from ice and snow, particularly at elevation, is commonly called snow blindness. [5] It can also occur due to using tanning beds without proper eyewear. Natural sources include bright sunlight reflected from snow or ice or, less commonly, from sea or sand. [6]

They can effectively deter further advances, regardless of language or cultural barriers, but can also be used for hailing and warning. [1] Targets can include electronic sensors as well as human vision. [2]
Upon detonation, it emits an intensely loud "bang" of 170–180 decibels and a blinding flash of more than one million candelas within 5 feet (1.5 meters) of initiation, sufficient to cause immediate flash blindness, deafness, tinnitus, and inner ear disturbance. [2]
At that strength, the laser can cause eye damage up to 52 feet, temporary flash blindness up to 260 feet, glare or disruption up to 1,200 feet and distraction up to 11,700 feet, according to data ...

Simulation of temporary flash blindness where the image takes from a few seconds to a few minutes to fade away, depending on how much light entered the eye. Light level 50 μW/cm 2; for example, a legal 5 mW laser pointer at 350 feet (110 m). The photos at right flash because most incidents are of flashes and not of steady illumination.
