For now, people are not limited to finding and enjoying low-output pointer laser enthusiasts. However, many laser enthusiasts are already considering using more efficient and environmentally friendly laser Pointers. Green laser pointer, that is, nearly 3 million to 700mW of a variety of full-size full-performance laser gadgets. In the past, red laser Pointers were used as auxiliary tools for powerpoint presentations, but their short range and lack of clarity made them less effective. The green laser pen adopts the green laser generator, which effectively overcomes the above shortcomings and has a good substitute. In the United States, laser designators regulated by the FOOD and Drug Administration (FDA) have a power limit of 5mW. In The UK and Australia, regulations are stricter, limiting devices to 1mW. To use more powerful equipment, you need to apply for a license.
Retinal damage from laser designators is actually quite common so there are a number of diagnostic criteria that can help determine when high powered laser burning can cause eye trauma. In fact, it doesn't take long for lasers to do real damage: in a 2012 case report, a 5mW laser pointer recorded serious damage to the eyes of a 13-year-old boy in just one minute. His eye eventually healed, but another 13-year-old boy was not so lucky, according to a 2015 case report. The 13-year-old had a brother who ordered a 50mW laser pointer from the Internet and shone it in the patient's eye for a second - causing permanent damage. In the United States, laser designators regulated by the FOOD and Drug Administration (FDA) have a power limit of 5mW. In The UK and Australia, regulations are stricter, limiting devices to 1mW. To use more powerful equipment, you need to apply for a license.
Danger is determined by several factors. One is output performance in watts or milliwatts. In the most severe cases, a person can go blind. The potential to dazzle cannot be ignored. Especially in the dark, it takes a few seconds for the dazzled to reassess their surroundings. This danger is very real for all people who drive vehicles or trains, as well as pilots. In this case, the display and driving instruments can no longer be read. On the steering wheel of a vehicle, it is impossible to distinguish people in crosswalks in time.
