[QUOTE="pmurph5, post: 892305, member: 37989"] I work in the field of lasers and laser safety. The scanners you are using are designed to be eye safe. Both the power of the laser, and the scan pattern are designed to be below the Maximum Permissible Exposure limits set by laser safety experts. In addition, the MPE itself has a built-in "safety factor" so that even if you are exposed to light above the MPE, the chance of injury is low. For comparison, in Europe and Asia a form of laser light shows called "audience scanning" is widespread. Laser beams that are hundreds of times more powerful and brighter than your scanning device are aimed directly into the audience. It is estimated that 109 million persons have been exposed to laser light well in excess of the MPE (10 to 100 times the MPE) over the past 30 years. So far, there have been 8 reported injuries. Also, almost all reports of persons injured with laser pointers involve high-powered pointers (far in excess of your scanner's power) that are often deliberately aimed into the eye of the person. Again, an accidental exposure to your device is perfectly safe. I would not look into it deliberately, but unless you are staring, no harm will be done. -- Patrick Murphy, webmaster, LaserPointerSafety.com [/QUOTE]
