A Simple Guide Prior To Using Laser Pointers
Safety using high powered laser pointers is a big concern among public and something that can’t be disregarded. Despite its brilliant beams, the use of high powered laser pointers and portable lasers as well can bring dangers to the eyes.
Whether you believe it or not, these pointers are representing 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. With this being said, you may be wondering on how these pointers are danger to the eyes? The 2 unique properties of the pointer is where you will find the answer to this question.
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.
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 avoid dealing with the dangers of these devices easily by just following simple guidelines.
Tip number 1. You must not point the laser to anyone even if it’s just horseplay, more so not point it directly 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. You probably do not want to take your chances, given the fact that you may possibly lose 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. 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.
