How does the EU view laser pointer products?
In the European Union, laser pointers must meet the Class 2 laser requirements of EN 60825-1. Among other restrictions, laser power output greater than 1 mW must therefore not be used. If it does not exceed this value, even if the laser beam hits the pupil directly, the risk of retinal damage is extremely low. Therefore, the problem is that many commercially available laser pointers actually have higher power emissions, sometimes exceeding 200 mW. If the power is too high, the laser beam hits the bottle and there is a risk of permanent damage. This is unlikely at close range. However, as the distance increases, the probability of hitting decreases rapidly, because the pupil diameter of the human eye and the beam diameter of a laser pointer are no different. Every experienced shooter knows how difficult it is to hit a small object at a long distance, and it is even more emotional if it is still. In addition, with a laser pointer, the effect also depends on the exposure time. Using a hands-free laser is unlikely to be particularly long. Compared with the pupil diameter, the diameter of the laser beam will have a very large hit probability and a longer exposure duration, but at the same time the irradiance will be reduced because the laser power will be distributed over a larger area. Therefore, when the Laser pointer is touched from a greater distance, the greatest danger is glare.

Adults should be especially careful when using laser pointers with green highlights. According to the study, up to 90% of the green laser pointers in the study did not comply with CFR regulations, while the red laser pointer was 44%. In addition to concerns about powerful lasers, many state laws prohibit young people from bringing laser pointers to school playgrounds or other places. Some jurisdictions take more measures and explicitly prohibit young people from owning laser pointers. For example, in New York, it is illegal to offer, sell, or even offer to sell lasers to anyone 18 years of age or younger. It is especially bad to aim a powerful 3000mw laser beam at anyone in uniform. It is not only very lame to irradiate police, firefighters, paramedics or other uniformed staff with laser light, it is also extremely illegal.
