Laser toys and pointers may be fun for children to play with, but when used carelessly, the powerful light they emit can cause serious eye injuries or blindness.바카라 게임 웹사이트�A beam shone directly into a person바카라 게임 웹사이트�s eye can injure it in an instant, especially if the laser is a powerful one,바카라 게임 웹사이트� says FDA Health Promotion Office Dan Hewett.Eye injuries caused by lasers can depend on several factors - the strength of the beam, the laser's wavelength, its time of exposure, movement and location. Even more alarming - visual harm caused by a laser may go unnoticed for days or weeks, possibly leading to permanent damage. "A laser creates a powerful, targeted beam of electromagnetic radiation that is used in many products, from music players and printers to eye-surgery tools," the FDA says. "When operated unsafely, or without certain controls, the highly-concentrated light from lasers...can be dangerous...not just to the person using a laser, but to anyone within range of the laser beam."It's not just high-tech toys that parents need to watch out for - handheld laser pointers can also be risky in the hands of children. The strength of these devices has increased at least ten-fold during the past decade, according to the federal agency.Here's how use laser toys safely: 1.
