Now your laser pointer test questions. In front of you is a cemetery and a tombstone with your name inscribed. Your task is to avoid making it the last word about you. You must avoid entanglement there. There is a way... the way. In a short time, the earth is currently warming for the extinction of life...All life is not just human beings. The ocean heats up and kills the plankton that provides us with breathing air; soon, people will find it difficult to walk up the stairs, stay awake, and eventually stay awake.
As part of the adaptive optics system, large astronomical telescopes also emit laser pointer in the sky, but in these cases, as long as the laser is used, the FAA and the military’s joint space operations center will be notified. In addition, the pilot’s segmented navigation map includes warnings, the observatory’s large friendly "Beware of Laser Activities":
We think that the human eye is like a camera, but it is very different. The human eye responds to the level of light it is exposed to, and the brain reduces the eye's response to light. The human eye has evolved to respond to the scope and spectrum of the world we face. Open your eyes to any level needed to understand what the sun shining object reflects from the object.
I don’t know how the eye sensitivity of flies compares to human eyes, but both animals live in the same environment and experience the same light levels, so I assume that they have similar eye sensitivity. So, inferring from human standards, I guess you can’t permanently damage the fly’s eyes unless you aim the laser at it, in the same relative position, for a longer time (at least a few seconds). The fly will not cooperate with you, so unless you fix it in some way, you are unlikely to cause permanent damage.
Also, please note that if you do stare at the green laser pointer and manage to damage your eyes, you have only damaged a small spot on the retina. You are not blind, you just have a new blind spot. It takes more energy or a lot of time to completely blind someone on the entire retina.
