A Simple Guide Prior To Using Laser Pointers
It’s a big concern in the public to apply caution when using high powered laser pointers and something that just can’t be overlooked. Despite its brilliant beams, the use of high powered laser pointers and portable lasers as well can bring dangers to the eyes.
These pointers represent real dangers to the eyes. Your eye’s visual receptors are part of the central nervous systems meaning, if your eyes gets damaged, then they wouldn’t be able to recover or heal. When it comes to power output, laser pointers are not actually releasing great amount of power like what you think. This is true most especially if you try comparing it to the typical 75 or 100mW light globe. Well, if that is the case, how come these pointers become a 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.
This not to say that you have to be afraid of using laser pointers but what you should do however is, treat it with respect and use it cautiously. After all, you can easily avoid dealing with the dangers of such by following basic guidelines which will ensure everyone’s safety.
Tip number 1. No matter what you are doing, it is never nice to point the laser to anyone, particularly straight in 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.
As long as you follow these 5 simple rules, you will be fine in using laser pointers.
