Red laser pointers are used for different purposes all over the world.

The expressway is relatively closed, driving at night is relatively simple, long-term driving is prone to fatigue, carelessness, and traffic accidents. According to the BMO editorial recently published by Professor John Marshall, despite the increasing popularity of high-power lasers, empirical studies may indicate that permanent scars of the retina cannot exceed a few meters, so the pilot’s risk is still very low. The main visual risks for pilots are momentary glare, disorientation, temporary blind spots and subsequent images, all of which can lead to serious accidents. However, over the years, pilots have fully understood the protocol to minimize the risk of potential attacks. "Laser" is an acronym for optical amplification of stimulated emission of light.

"The anti-fatigue driving high power laser pointer transmitter has a long irradiation distance, and it will have a certain visual impact on the driver at night or under poor visibility conditions." At night, the laser beam automatically turned on by the laser engraving machine emits a frequency. Flashes, always bright green, forming a laser band, encouraging the driver to drive safely. The red laser pointer is the first handheld laser pointer on the market, and it has set off a boom. It seems to belong to everyone you know. The first red laser pointer was released in the early 1980s. It was a large device that cost hundreds of dollars to buy. Laser pointers can directly injure the eyes and cause dangerous situations by distracting them. As of 2011, despite many guidelines and many incidents of malicious or unintentional use, the low-power guidelines did not report very serious and permanent eye injuries. .. The risks are obviously real, but they are the cause.
