Why laser pointer can cause blindness？
Scientists use a 1.5 megabit laser to observe the human eye and compare it with the energy produced by the sun. They found that the voltage emitted by the ghost laser was 80 times that of the sun. It is actually burned through by so much light. What is a laser? Why does a small Laser pointer make a child blind? Laser is the light of electromagnetic waves. Different from normal light, the "orderly, functional, and orderly" light on the ship has high brightness, high texture, and high consistency. The communicative ability of laser power exceeds one billion.

With advanced technology, it can pass directly through the eyes without spreading. Therefore, the light spot on the eyeball is very small and the density is high. The internal temperature of the eyeball tissue rises rapidly. Because its heat reacts to eye damage, laser light can damage children’s eyes. The greater the intensity of the x-ray, the larger the macula on the child’s eyes. This is why you should pay special attention to the fact that once the injection is in the eye, the doctor will check and treat the eye in time to prevent the wound from getting worse. The human eye is a very complex cell that grows in the body. 70% of the news comes from the eyes. The eyes may be damaged by laser damage. Lasers are three damage mechanisms: scalar effect, thermal effect and radiation effect. Laser waves have different effects on eyes and eyes. Visible infrared lasers can form infrared bubbles. The pulse is too fast and the laser gun penetrates the skin.
