In the past few years, the laser pointer has attracted attention in the media and has attracted some public attention. As a consumer product, laser engraver are designed to be safe when used for their intended purpose. Unfortunately, laser pointers can easily be abused.
From a laser safety point of view, the situation becomes more complicated with the development of new diode lasers that generate light at 670, 650 and 640 nm. As the wavelength emitted by the diode laser gets shorter and shorter, the power output level has been maintained at 5 mW.
Therefore, today we have a 640 nm 5 mW blue laser pointer pointer beam, which is very bright for the eyes. In addition, there is now a brighter indicator on the market with a wavelength of 533 nm (green). This new technology uses a frequency-doubled neodymium:YAG laser, and the infrared component is blocked.
Use the laser pointer safely
Do not aim the laser at vehicles or airplanes. Therefore, death or serious injury may result.
Do not let children play with laser pointers.
Do not aim the laser directly at people or animals.
Only toy lasers labeled “Class 1 Laser Products” can be purchased. This means that the risk of laser is low and safe for children.
During riots or civil strife, some protesters aimed the laser at the police’s sight. Where this situation is common, the police can now use goggles.
In the sports game, the audience pointed the laser pointer at the football goalkeeper and other players. This is non-sporty (to say the least!) and a potential eye hazard to the player.
In concerts and movie theaters, sometimes audiences find it interesting to shake the laser dot on the stage or screen.
Laser pointers have been aimed at cars, buses, trains, ships, barges and ferries. Just like an airplane, this can distract the driver or pilot or make them temporarily blind-which is obviously unsafe.
If you suspect an eye injury, please contact a doctor immediately.
When viewing marketing materials, please pay attention to the following keywords: powerful, bright, super, super, military grade, powerful, blasting, burning, burning, adjustable focus, lithium battery and lithium power.Eye injuries caused by lasers are usually not injured. Therefore, it is better than regretting, to be safe and not to let all laser pointers close to the eyes.
For direct eye injury, the exact severity will depend on many factors: beam power, exposure time, relative movement of the beam/eye, distance from the laser, location of the retinal injury, and the person’s physical/genetic susceptibility to eye injury (some People are more sensitive than others).
