A question about laser mice.

[The_Absolute]

I know that lasers can be extremely dangerous to the eyes. Causing severe vision damage and/or blindness if a laser gets in your eye. I know that this holds true with laser pens, but does the little red laser from a laser mouse pose that same hazard? Or is it harmless?

[DavidSnider]

They are class 1. Pretty much harmless.

A laser's hazard rating has to do with it's total power output. A laser in a mouse is very low power and does not pose a significant hazard to the user unless they hold it up to their eye for hours at a time.
