Exact quote from Sam's Laser FAQ - Laser Safety ---

" A cheap laser pointer also produces a highly collimated beam.

Even at power levels considered relatively safe, one shouldn't deliberately stare into the beam for any reason. For these relatively low power lasers, permanent eye damage is not that likely but why take chances? For these lasers, viewing the spot projected on a white surface is perfectly safe."

Default Re: <1mw laser in eye

He must be referring to the chances of stabbing yourself in the eye with a laser. For actual damage to occur, the laser needs to cause localized heating in the eye, which a true 1mW laser won't do, especially red.

Note that a fair few "1mW" lasers aren't actually 1mW

I was referring to "Pointer" lasers in general, which are considered 5mW and under, due to the fact that his may very well be more than 1mW, but unlikely more than 5mW.

Edit: But yeah, basically no matter how you look at it, your eye is fine, we're just stressing the importance of laser safety, as this is a forum for those more extreme laser-owners.
