Laser pointers are usually used as a complementary tool in presentations. Unfortunately, these laser toys are often misused for the wrong purposes. Fanatical fans of the football team often smuggle these toys to fire their rays directly from long distances right into the eyes of the opposing team players. The goal is none other than to confuse the opponent and disrupt the running of the match. But even if it seems trivial, the danger of laser toys should not be underestimated. Directing the right laser beam towards the eye can cause blindness.
The danger of a laser toy that turns out to be able to make it blind
The FDA as a POM body in the United States which is equivalent to BPOM in Indonesia states that the danger of laser toys that are used carelessly can cause serious eye injuries, even blindness. In fact, the effect can be more dangerous than looking directly at the sun.
According to Dan Hewett, health promotion officer at the FDA's Center for Devices and Radiological Health, the danger of laser toys whose rays are directed directly at the eyes can damage the eyes in just a moment. Especially if the light is strong enough. In addition, the effect will also be much worse if done at night when the pupils are wide open.
Light laser exposure in a short period of time can cause temporary vision loss. Because the light of the laser beam produces heat energy that can damage the eye tissue. This is what happened to a boy in Greece. He suffered blindness after repeatedly staring at the laser pointer when playing.
Quoted from Live Science, the child's retinal eye was reported to be hollow due to a laser beam. Even after one and a half years of recovering from surgery, his vision cannot return to normal.
Laser toys with blue and purple rays are more dangerous
The FDA limits the sale of laser pointers to only a maximum of 5 milliwatts. However, laser pointers sold on the roadside or online stores may not include the right labels, or they may have higher energy power than what is indicated on the label. So, it is difficult for consumers to know exactly how strong the laser pointer energy is.
Moreover, quoting from the American Academy of Ophthalmology, laser toys that glow blue and purple have a more dangerous effect than those with red or green lasers.
This is because the human eye is actually less sensitive to blue and purple compared to red and green. This makes your eyes not blink or turn away as soon as they are exposed to green and red light.
Because the eyes are more "resistant" to exposure to blue and purple light, then there is an opportunity for you to be able to continue to stare at the light for longer periods of time without realizing it. Even the injuries that are produced are more likely to be potentially fatal.
