I think that's rule number two. Right after "don't look at the laser".

then the third rule must be, "now you can do whatever the fuck you want" written in Braille.

the other saying I know is: "you can see laser only twice in your life, once with your eye and second time with the remaining one"

When I was a kid, I tried to look at it and nothing happened just like my friends said. All warnings failed to deliver a message that eye damage may be delayed and invisible at first. I didn’t lose sight after 30 years, so that laser was probably safe, but for fucks sake can they write non-dismissable warnings instead?

Reminds me that stupid low bridge warning: “overheight must turn”. Instead of messaging to a driver that they are overheight right now it just reads as a general rule. Numerous incidents per year as a result.
