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.
Nothing causes instant damage. (See Into the Sun for an interesting take on it) The question then comes, how much exposure will damage your eyes. The Straight Dope has a very good article on this: Can laser pointers damage your eyes? As does Scientific American: Can a pocket laser damage the eye? The big take is that (until recently) the most powerful laser pointers available would cause you to blink before it would do damage to your eyes (about 0.25s).
