In recent years, toy laser pointers have been popular among elementary and middle school students at low prices. Eye safety has become a social issue when used for gaming purposes. In the summer of 1997, there were reports that there had been incidents where the red light from laser pointers hindered professional sports, but recently, laser pointers are readily available and become a popular product for children to play. Exposing human eyes to the instantaneous displacement of Class 2 or Class 3 laser beams can cause temporary flash blindness, after-images, and glare.

There is an auxiliary police officer who is an ophthalmologist teaching Lu.

If you are hit by a laser pointer or other laser (for example, during a laser show), you may experience some other symptoms. Some are more common, some are less common. These are the most common symptoms when you hit the eye with a laser. Headache-Headache is one of the most common symptoms of laser pointer eye masks. This headache can last from an hour to several hours, which is the result of the amazing sensations you get from the laser. This is a normal physiological response to this type of electric shock, so you don't need to worry about it. Another common reaction when laser hits the eye is tearing. Just like a headache, the production of tears is a completely normal response when laser light hits the eyes. It is a response to laser stimulation.
