There is a lens in the front of the eye, and its optical function is similar to a convex lens. If the convex lens is placed in the sun, the light will be concentrated near the focal point through refraction. It can be seen that the laser pointer will cause more and more damage to the eye. Buy a laser When writing a pen, you need to carefully observe the instructions or ask the seller about the product model and specifications of the laser pen, or check the information online to purchase. Choose the Laser pointer that suits you to avoid harm caused by improper selection. Read the instruction manual when using it. After use, place it in a place that is not easy for children to reach.
