Laser danger?
I am not minimizing the potential danger of laser pointers but why
don't we see stories about drivers of cars being blinded or simply 2 kits playing with one being blinded for life? Terrestrial victims will be relatively close together. Somehow if you are in a plane or helicopter 4 miles away, it is "instant Ray Charles". If these are so dangerous, why hasn't CPSC sent them down the road with aluminum wire and lawn darts? |

I don't think the lasers you can buy as a "laser pointer" are all that dangerous as far as exposure to the laser beam is concerned. They are only 5 millwatts (max) and you would have to stare at the beam at close range for a relatively long period of time to cause permanent eye damage. It's possible, if you are an idiot and stare at it without blinking for a while but that's unlikely. I think the danger is more in the unexpected distraction experienced by pilots and perhaps vehicle drivers. Again, if this is so bad, why don't we hear the complaint from drivers. (I hit the parked car because someone blinded me with a laser etc) Back in the 80's there was a major DOD program to develop thin film optical blocking systems for several different laser wavelengths. The concern was that an adversary (Soviets at the time) using relatively high powered lasers could blind and injure the eyes of soldiers viewing their surroundings through optical magnification systems such as rifle scopes and targeting systems in tanks, etc. Those lasers were rated in watts, not milli-watts. We had a pretty nasty red laser in our printers. Old school deal that about 2 feet long (not a diode) but it was still only putting out 350mw or so although I think it was capable of a lot more. |
