I am a bit worried about the experiments of my current roommate, i know
he is a very competent engineer but he has the habit of playing with lasers.
Now he has a dvd burner laser inside a penlight housing which can reach
across the park here (and that's VERY far, but i'm worried about he (or
me) accidently staring into the beam and i can imagine if it burns dvd's
it will burn eyeballs, or not?
So, my question is if there are glasses... one can use to protect from
laser radiation.
Or am i on a wild goose chase and is it not as bad as i hear everywhere?

Oh yeah, get the glasses. They're cheap, especially compared to an
eyeball. We do some serious laser stuff at work, and the joke goes that
you only get to see a laser once with each eye. Looking at it from the
side is not a problem, but things happen. The door is locked and the big
red warning light is on when the laser range is active. Absolutely
foolish to **** with the thing in a public park.
