Medical Video: The Robot That Shines a Laser in Your Eye
Laser pointer usually used as a complementary tool in the presentation. 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 opponents and disrupt the game. 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 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 be much worse if done at night when the pupils are wide open.
Laser light exposure in a light level in a short 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 beam pointerwhen playing.
Quoted from Live Science, the child's retina was reported to be hollow due to a laser beam. Even after one and a half years of recovering from surgery, his vision could not 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 a higher energy power than what is indicated on the label. So, it is difficult for consumers to know exactly how strong the energy of the laser pointer 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 as fast as when 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. The resulting injury is also likely to be more potentially fatal.
