Temporary visual impairment can interfere with the ability to detect or distinguish visual objects after exposure to bright light. This is similar to the effect produced by a flashlight, and may occur at exposure levels below that cause eye damage. This damage is short-lived, lasting from a few seconds to a few minutes, depending on the exposure level and time of the Laser pointer, the visual task, the ambient lighting, and the brightness of the visual target.
Glare: Reduced or complete loss of visibility, such as that produced by strong light sources (such as oncoming headlights) in the central field of view. These visual effects can only last if the actual light affects the individual's vision. Even at energy far lower than the damage to the eyes, visible laser engraver can produce glare and interfere with vision.
The laser pointer contains metal, plastic and electronic parts. Each of these industries has specific waste by-products (solvents, halogenated hydrocarbon gases, lead, chemicals), but the laser pointer components have no specific waste before disposal of the laser pointer. The laser pointer contains a small amount of harmful substances, such as lead and certain toxic semiconductors. As with other electronic components, it may be safer to recycle the environment in the long run, although it is expensive and there are few plans to recycle or reuse electronic products. It may change in the future.
In addition to the aforementioned light-induced factors, blue laser pointer these factors will definitely affect perception in key visual activities. The author also believes that there is another factor. This is a situation where the individual is exposed and has a clear perception of potential harm. In some cases, this may cause reactions based on other factors such as retinal damage or blindness. This will be considered "perceived hazard" (CPH). This is often called "anger". There is increasing evidence that certain people who are exposed to radiation that is generally considered harmless can see adverse physical effects. In this case, the exposed person feels "harmed." In this case, the person feels "angry" at the feeling of being hurt and is convinced that the hurt has occurred.
