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.
You cannot physically damage a person's eye with a laser pointer. You can however, decrease the activity in the inner eye which relays a signal (blindness) after a period of t â¦ ime while staring into the laser.It is not strong enough to damage, but bright enough to cause dysfunction of your pupil.he laser diode in laser pointers can't change frequency, so the diode itself has to be switched. Other colors can be mixed together though, so yellow â¦ can be achieved by a red diode and a green diode in the same casing.
