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? The answer to that lies into 2 unique properties of the pointers.
Number. 1 focused and coherent – the way how the energy is released from these pointers follow the same principle as what magnifying glasses do in 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. Never look directly into the laser’s beam under any circumstances, even if it’s just a low powered laser. Probably, you don’t like to take your chances, considering that it may potentially damage your vision.
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. The reason for this is that, the beam will bounce back and damage your eyes.
Tip number 4. Like what’s mentioned earlier, you have to practice caution when using laser, ideally in a 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.
If you stick to these guidelines and practice care and common sense, you’ll do fine in using laser pointers.
