Even moderately powered lasers can cause injury to the eye. High power lasers can also burn the skin. Some lasers are so powerful that even the diffuse reflection from a surface can be hazardous to the eye. Diagram of a human eye. The coherence and low divergence angle of laser light, aided by focusing from the lens of an eye, can cause laser ...
To give another example, of a more powerful laser—the type that might be used in an outdoor laser show: a 6-watt green (532 nm) laser with a 1.1 milliradian beam divergence is an eye hazard to about 1,600 feet (490 meters), can cause flash blindness to about 8,200 feet (1.5 mi/2.5 km), causes veiling glare to about 36,800 feet (7 mi; 11 km ...
The dazzler can be seen at the top-right, located behind the gunner thermal sight. Weapons designed to cause permanent blindness are banned by the 1995 United Nations Protocol on Blinding Laser Weapons. Dazzlers intended to cause temporary blindness or disorientation fall outside this protocol. [citation needed]
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 ...

The Protocol does not prohibit attacks against binoculars, periscopes, telescopes, and other optical equipment because it was unknown whether laser attacks on such devices could cause permanent blindness. [4] Article 3 allows for attacks on electronic optical equipment, because damaging it would not cause human injury. [4]
Even lasers with a power output of less than one watt can cause immediate and permanent vision loss under certain conditions, making them potentially non-lethal but incapacitating weapons. However, the use of such lasers is morally controversial due to the extreme handicap that laser-induced blindness represents.
