Are laser indicators dangerous?

Laser indicators are visible lasers with relatively low power, which are often used in lectures and demonstrations to show them the topics of interest on the presentation board. In the school environment, they have become ubiquitous and very useful teaching aids are very useful.

More frequent use of these devices has been worried about their safety, especially around the eyes. These problems include flash blind, glare and consequences. Lightning blindness occurs whenever someone is exposed to a bright light source. Although it only takes a few seconds, it can be very dangerous when someone is involved in a task that requires a vision such as driving.

fortunately eye problemsThe complaints associated with laser indicators are not in the form of permanent damage. However, a reduction in visibility may certainly be a danger and for this reason these devices should be used with care. It can also lead to deep optical damage if the exposure is extended. Most laser indicators have very low power, but when it is focused on the retina through the eye lens, it can cause damage. It can constantly stare into the laser with a fully widespread eye for more than one minute can cause the retina burns.

In most regions, laser indicators are regulated. The device should have a "caution" label, which also shows which class is the laser and performance. Many laser indicators are IIIA devices, which means there is a potential for damage with direct exposure to laser. Class two are less strong and are a better choice if you are worried about safety. However, the lower light outlet may not be effective in the lecture hall.

If it is responsible, a laser indicator would not becould present a danger. It should never be used as a toy or aimed directly at someone else.
