Exposure to a laser pointer?

Question

yesterday this one idiot who sat next to me on the bus pointed his red laser pointer on his keychain directly in my eye for like 1-2 seconds .. i dunno what kind of laser it was but I didnt seem to experience any vision problems (i also wear glasses) what im worried about is that would the laser **** my eyes up in the long run .. also another question.. is it hazardous to look at pictures of laser beams on the internet.

Answer 1

Most laser pointers have low enough power that the projected beam presents a minimal hazard to eyes for incidental exposure. Consequently, beams from laser pointers are generally not visible from the side in normal clear air, but only visible as a point of light where the beam strikes a diffusely reflective surface. Some higher powered laser pointers are faintly visible via Rayleigh scattering when viewed from the side in moderately to dimly lit conditions.

Answer 2

if its a class 1 laser then it cant ruin your eyes and it probably is a class 1 because its just a cheap keychain a class 2 laser can hurt your eyes if you look directly into it for about 3-4 seconds and class 3 laser can ruin your eye sight if you look directly in it for 1-2 seconds and i class 4 laser can ruin your eye sight if you look into it directly for even a millesecond so your fine

Answer 3

When a laser does damage, it is immediate.

If you don't have permanent black spots in your vision right after... then there was , and will be no damage.

No, seeing videos of a laser can't do anything to your eyes...it isn't real, it is just an image of it.

Imagine what seeing videos of an atomic bomb could do otherwise....lol
