You are not a laser expert. If you were, you would know what flash blindness is.
Tell you what, Mr. Laser Expert. If you are so sure of yourself, go sit in a darkened room for 20 minutes and then have someone shine a green laser pointer at your face and tell me what happens next.

First of all the room being dark would have nothing to do with it...
Second, if the room were big enough and the “someone” were miles away, it wouldn’t be an issue. It would be much more dangerous to just walk into a stationary beam, since a hand pointed beam would be moving since this “someone” would not be able to hold the laser still, yet a stationary beam would only be moving with respect to my face based on my movement (which would be slower and much more restricted).
I don’t know if you can grasp this, but the angular 2 axis movement of the beam increases with the square of the distance. At a mile your “someone” couldn’t hold the beam steady within a couple hundred feet.
