Is the 50MW Violet laser pointer dangerous?

Most laser Pointers are not considered dangerous when used responsibly. However, as the availability of these devices has increased, so have reports of their inappropriate use. As a result, the Food and Drug Administration (FDA) issued a warning in December 1997 about the possible harm that handheld green laser pointer can cause to children's eyes (see annex). The FDA issued the warning because of two reports of eye injuries caused by misuse of these devices. Of particular concern is the promotion of laser equipment such as toys. Some laser designators can transmit more damaging light to the eye than looking directly at the sun. Temporary exposure to the laser can cause discomfort and temporary visual impairment, such as glare, blindness and the retina, without causing permanent physical damage. Glare involves a reduction or loss of visibility in the central field of vision during exposure to a direct beam of light from the pointer. The effect is similar to displaying oncoming headlights at night. Once the beam disappears, the glare becomes unresponsive. Blindness is a temporary loss of vision after seeing bright light. The effect of a 200MW purple laser pointer is similar to looking directly at a flash while taking a photo. The attack can last for several minutes. Viscosity involves the perception of spots in the field. These images can be distracting and annoying, often lasting for several minutes. Visual impairment can be dangerous if the exposed person is engaged in important visual activities, such as driving a car or aircraft.
