For "casual" use lasers (classroom, grocery store scanners) it looks like the limit is 1 milliwatt (this from reading the warnings on ads for various devices). The warning on lasers of less than a milliwatt is "Don't stare stupidly into this bright light". Anything above that carries a warning of that indicates that it should not be pointed into people's eyes at all. This is for helium-neon reddish lasers. I don't know if laser damage to the human eye is strongly correlated to frequency. -- Dan Liddell UUCP decwrl!teda!dll TELEPHONE 4089805200 USA curb your dogma.
