The reason why many people still use high-power lasers is the visibility of the beam.
Since July, the law has strengthened the use of these green high powered laser, which can damage the retina and cause irreversible accidents. A crime was created in the framework of Loppsi 2 in 2010.

Low-power laser pointers choose pen-style design, high-power lasers choose manual flashlight design to make more space for larger laser modules. High-power pocket lasers require more space as a thermal stabilization system. The pocket laser always adds the ability to adjust focus protection and safety keys. To get the best laser protective glasses, please see the laser technology process. From traditional demonstration indicators and high-combustion lasers to laser eye protection systems and laboratory laser systems, be sure to research and look for a warranty period of 12 months or more.
