Dangers of DX "5 mW" Green Laser "Class IIIb"

[BowtieGuy]

This paragraph was located below the graph that Alaskan posted, it is their(LaserPointerSafety.com) explaination.

"Note for careful readers (such as those at LaserPointerForums.com): Some observant people have noticed that there is no flashblindness distance indicated for the 1W blue handheld (e.g., no red part on the bottom bar). This is because the flashblindness distance of this laser is only 646 feet. That’s shorter than the 733 feet which is the eye injury hazard distance. Here’s how to think of this. The laser’s blue color appears relatively dim to the human eye. Beyond 646 feet it doesn’t appear bright enough to cause flashblindness, yet it is still within the eye injury hazard distance of 733 feet."

aha... I looked at the one graph and saved the page for later reading. Makes complete sense, thanks.

That was a trip when I read that after noticing and asking about it on LPF. lol! It was like it was written for me in real time. Is the writer part of the forum?
