bus driver suffers vision loss from child\'s toy laser

by:EME LIGHTING     2020-03-20
A new case report shows that a boy used a laser pointer in a toy to target the rearview mirror inside a German bus, permanently damaging the retina in the driver\'s right eye of the bus.
The boy sits about 50 feet metres playing with the laser indicator (15 meters)
Stay away from the driver, according to the case report.
When the child points the laser to the rearview mirror inside the bus, a red light emitted by the toy reflects from the mirror to 44-year-
According to a report released online on October, the old bus driver.
In the case report of the British Medical Journal.
The laser indicator is a handheld penlike device that is usually used in lectures and business presentations to highlight information.
Astronomy enthusiasts also use them to point out planets and stars in the sky, which are also available in some children\'s toys.
The boy\'s laser is part of the toy and initially, the light creates a blurry vision in the driver\'s right eye of the bus.
After this blur lasted for six months, the driver asked the eye doctor for help.
After checking the driver, an eye doctor diagnosed mild but detectable damage to the rash, which is the area responsible for central vision near the center of the retina.
However, the driver\'s vision is still normal in his left eye. [

The driver looked at the rearview mirror about three or four times in an attempt to identify the passenger holding the laser, causing additional exposure, increasing his chances of an eye injury, the report said.
The doctor wrote in the man\'s case report that this was the first reported case of retinal damage caused by the laser beam of the toy.
The doctor said that the laser can make the light from the laser beam, even if it is reflected by the mirror, it can be absorbed by the pigment structure inside the retina, which produces heat and causes minor burns
Vincent patarano, director of ophthalmology at Cambridge Health union and assistant professor of ophthalmology at Harvard Medical School in Boston, did not participate in the case.
This tiny burn, he says, destroys a small area of the retina, thus damaging the central part of the person\'s field of vision.
Although lasers can be used to treat some vision problems, such as retina damage that sometimes occurs in patients with diabetes, patients are told not to stare directly at the light, and patalano tells Live Science that the use of lasers is very short.
The light emitted by the laser has several properties, which can pose a danger to unprotected eyes. Laser-
Patalano says the light produced is kept together on a narrow road, and it is concentrated on a small point.
The laser is also a color, he said, and the eyes are more sensitive to light in certain colors than in other colors.
In this case, though, the laser is red, and the damage to the eye is not as good as the blue or green laser, he said.
The intensity of the laser varies, says Patalano.
Although it is not yet known the exact energy output of this boy\'s toy laser indicator, it may be a low energy output
The case reported that the energy laser.
There is nothing to do to correct this type of visual impairment, says Patalano.
Patalano suggested that it is not clear why the laser affects only the male right eye, but it may be that the beam is reflected at a slightly different angle in each eye.
There are other incidents where laser pointers are reported to have been misused, causing eye problems or putting people at risk of injury.
According to a report by the Federal Aviation Administration (FAA)
Fans have disrupted sporting events with laser pointers aimed at athletes, and people use laser pointers to target planes or helicopters.
This is a federal crime in the United States because strong light can temporarily blind pilots and make it difficult for them to fly and land planes safely.
According to the agency, pilots reported about 3,900 laser incidents to the FAA in 2014, of which nearly 4,000 occurred in 2013.
The author of the case report finally suggested that because children are unlikely to understand the possible risks of lasers, children should not be allowed to use these devices.
