Is it dangerous to view the point of a high powered laser if there are no risks of hitting a reflective surface? Obviously if it happens to reflect off something it can cause permanent damage but is it safe to look at the "dot" of a 200mw green laser on a white wall from 2-3 meters away without protective glasses?
It seems like most concerns are from having accidental reflections, but can merely looking at the beam on a wall for a few seconds cause permanent damage?
