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 ...
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.

While it is caused by bright light similar to flash blindness, the welder's arc lasts for much longer than flash blindness and involves exposure to ultraviolet rays that can damage the cornea. Flash blindness, in contrast, is caused by a single, very brief exposure which oversaturates the retina , and is not usually accompanied by reports of pain.
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 ...
