The issue is that at present there are increasingly lasers within the invisible spectrum. Both ultraviolet or infrared. If you cannot see the sunshine, you won’t look away or together with your eyes or your digicam. Invisible lasers could be so highly effective which you can soften or reduce issues with them. That’s fairly creepy. The US are engaged on lasers that may shoot down planes. These lasers are additionally invisible.
I ponder how highly effective lidar lasers in self driving automobiles are allowed to be, as they need to have sufficient energy to “see” issues in just a few hundred metres distance. A future with self driving automobiles would meand that lasers would hit our eyes on a regular basis, if automobiles are close by.
