laser pointer is not a toy

American Academy of Ophthalmology, Martin Mainster, MD, PhD, advises parents to keep laser pointers away from infants and children in August 1997 issue of Ophthalmology, the journal of the Academy.
Guest editorial, Dr. Mainster explained that there are different classes of lasers with different amounts of energy, and laser pointers are class 3 devices with a power output of less than 5 milliwatts. Class 3B that ophthalmologists use to conditions such as retinal detachment and other diseases of the retina for the treatment of abnormalities, the level at 100-500 milliwatts of power and can be a serious hazard if improperly used eyes. He argues that "it is theoretically possible to produce (damage) of the retina, setting the third class in a collimated laser for more than 10 seconds, so it is important to keep away from infants and laser pointers Children. "
In December 1997, the FDA issued a warning to parents and principals about possible damage to the eyes of children in high power laser pointer . This view was immediately two new school activities in which an experienced teacher, a 10-days after the image and loss of vision led Cheerleader exhibitions laser pointer. The FDA warning states: "In light of Class 3a lasers are so intense or more intense than the sun" is drawn, and concluded that "the harm to be associated with these products appear to be related to improper use ". FDA Deputy Commissioner Michael A. Friedman, MD, said that the laser pointer are useful tools for adults to be used by children with adequate supervision."
In the editorial of Ophthalmology, Dr. Mainster explains that laser pointers are not the same risks, because the adult "students, flashes, and aversion to complete the response random laser pointer exposures of less than 0, 25 seconds. " He also stressed that "to avoid the label of a class 3 users a red laser pointer, laser pointer looks like a warning to his eyes," and concluded: "It makes sense to follow this advice, as it is good and healthy, common sense is not in a 35 mm slide projector headlights or an engine to come to watch.
