I must say, I’m sorry, this place called "church" is not a place where you can go for help, but in fact, the church is a collection of your best friends who have received God’s first and most precious gift The laser pointer changes the Holy Spirit of your life, guides you home, helps you distinguish right from wrong, and answers your first question through the feeling in your heart.
Most of the answers listed have no science to support emotional responses. The laser power available to the public does not cause any retinal damage. In fact, no laser can do this unless you look directly at the beam path. The laser beam will lose its intensity as the travel distance increases, and will spread out-you can use any lecture-type laser printer to make simple observations, or find a laser system that monitors the position of the moon. However, the system can only return 5 The best technology for photons around the world.
In fact, one might think that a laser is very similar to an incandescent lamp, because too much distance will reduce the intensity. that is not true. The laser beam may distract the pilot's attention and cause injury to the pilot. The person pointing the laser at the airplane is creating a situation that can cause major problems.
It's whether you can distinguish a light spot, it depends on the direction you look like anything else. If you are a few miles away and someone points a green laser pointer in your direction and happens to aim your eye, you will definitely see it. However, if the pointer points to the wall next to you, you will not know where it is.
But the question is, even if technically speaking, can you detect it in the extreme circumstances of travel? Due to divergence (beam spreading) and absorption attenuation, it may not be in the extreme state of travel, making it very weak. You need sophisticated detection equipment instead of eyes.
