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 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. Contrary to what you think, these laser pointers aren’t actually bringing immense amount of power. 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? The answer to that lies into 2 unique properties of the pointers.
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 doesn’t literally say that you must steer clear from using laser pointers rather, you have to learn how to treat it right and carefully. After all, you can avoid dealing with the dangers of these devices easily by just following simple guidelines.
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. It is your job to be conscious of your surroundings and check if there are reflected surfaces like glass, mirrors or metal polished; if there are, then don’t use your laser pointers. It’s due to the reason that the beam may reflect and cause harm to your eyes.
Tip number 4. Consider to only use the laser when you are in a controlled place because like what’s mentioned earlier, you have to apply caution when using it.
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.
