Basic Info Before Using Laser Pointers
Safety using high powered laser pointers is a big concern among public and something that can’t be disregarded. Despite of its ability to burn and brilliant beams, these high powered laser pointers as well as portable laser are a danger to the eyes.
The danger that these pointers represent into your eyes are no laughing matter. Your eyes wouldn’t be able to recover or heal because its visual receptors are part of the central nervous system; so better learn how to take care of it. When it comes to power output, laser pointers are not actually releasing great amount of power like what you think. This is true especially when you try to compare it to normal 75 or 100mW light globe. If that’s the case, how come that these pointers are danger to one’s eyes? As a matter of fact, the answer to this question lies in the pointer’s 2 unique properties.
Number. 1 focused and coherent – the energy coming from the pointers are concentrated on a very small area much like the way how a magnifying glass is focusing the sun.
Number 2. Collimated – the light does not spread even after it’s beamed out from the laser instead, it stays in a narrow line making the lasers to be a real threat especially at close distance.
Well, this isn’t to say that you should feel afraid for using laser pointers but what you must do is to treat it with respect and apply caution when using it. In the end, by following simple guidelines, you can ensure that everyone’s safe and avoid the dangers of such.
Tip number 1. You should never dare to point the laser at any person most especially directly into their eyes.
Tip number 2. Don’t look directly to the beam of the laser under any circumstances, even if it is only a low powered laser. No one wanted to lose their vision of course, so why would you dare to take your chances in doing such thing.
Tip number 3. You must be aware and conscious of reflective surfaces around you when using laser pointers like polished metals, mirrors or even glass. It is because of the reason that the beam can reflect and harm your eyes.
Tip number 4. Like what is said, practice caution when using the laser, preferably only in controlled environment.
Tip number 5. Unless someone who plans to borrow your pointer knows how to use it and dangers that come with them, don’t let anyone borrow it.
As long as you follow these 5 simple rules, you will be fine in using laser pointers.
