Are you still using laser pointers with high power? I think most of you do not strange to laser pointers, it is a little pen release a red or green light once you click it. We always used it when we making a PPT report and we need it to point out the key points what we are talking about. Or we may also be able to print some lovely picture in the wall by using them.
Presentation laser pointers have make our life more convenient, but there is some bad thing happened with the coming of this cool gadget.
For example, in the preliminary contest of European championship2011, England's player Tony Parker was into a disturbance by the laser pointer. And early in 2008, Lyon fans irradiated Cristiano Ronaldo's face with a laser pen for many times, so that has triggered strong protests from Manchester team.
However, there are still some people who use the laser pointer to harm the fly of the plane in the night. In fact, the dangerous of laser pointers are stronger than you though. Because once if the laser pointers was exposure in the pilots who driving absorbed, consequences cans be imagined; And take-off and landing stage itself is a high incidence of accident at that time, if the pilot encounter interference by the powerful light, the situation will become more dangerous.
Besides, laser pointers can also hurt our eyes without a good use. Looking into the laser power of 5 mw and above will cause temporary vision damage to eyesight; the more powerful will cause permanent eye damage or even blindness.
What's more, high power laser may ignite flammable and cause a fire. Some high power laser pointer, diffuse light may also cause harm to the eyes, focusing more likely fire on the flammable items.
But not all of the laser light source will cause harm to our eyes, once we've taken the appropriate protective measures, as long as there is some protection in the process of operation behavior, then this type of damage is very small. Here we suggest all of our friends to use laser pointers in a reasonable way to avoid hurting from it.
