My job is to manage the warehouse parts in the factory. It's a little dark. I want to do laser, but I'm afraid it will be bad for my eyes to work in dark environment, and I want to do it occasionally
Laser energy is strong or weak, and it will hurt some people's eyes. I wonder what you want to do with lasers
Oh, well, can't you see the light? Does the light include? That makes no sense, huh?
However, since most lasers are invisible, all need to be protected.
Laser directional is good, but laser reflection on the object, as long as the light does not reflect into the eyes, there will be no impact
