How Lasers Damage the Eyes. Be it an accident or on purpose, staring into a laser pointer can cause some serious damage to your eye. The kind of damage caused (permanent or temporary) is determined on a case by case basis. Damage also depends on how strong the laser is.
Some injuries were accidental, but others involved a playmate intentionally pointing the laser beam at the victimâs eye. The distance between the victimâs eye and the laser beam ranged from a half-meter to 6 meters, roughly 1.7 feet to 20 feet. Those who suffered retinal holes were injured at the closest distance, around a half-meter. Generally, injury from greater distance resulted in less serious damage.
