Garden-variety laser pointers aren't the same as the newer

No, they are not. They are still not the most collimated beams
around, but they are collimated enough to cover just about the area of
a person's face at a few thousand feet.

The total energy delivered to the eye in this case would be in the
range of microwatts at several thousand feet, and it would be
virtually impossible to accurately aim a handheld pointer at this
range. So it would be more of a nuisance to vision than a damage
hazard.

Unfortunately, there are still more powerful lasers available. Most
people dramatically underestimate the hazards of laser light. I'd be
nervous about those green pointers just out of concern for my own
vision. All you have to do is accidentally aim it at a reflective
surface, and next thing you know you have a retinal burn



You;re an idiot and as usual, are missing the point altogether.
