Recessive Killer of Your Eyes - Be Careful with Laser Pointers

Laser pointers are useful when used at a business meeting to point out areas of interest on a chart or graph. Laser pointers also have been used during visual presentations for years, usually there are teachers or lecturers use them to highlight key areas on charts and screens.

And it is also very amusing when the kitty chases them around the floor. But, innocuous as they seem, even the weakest of laser pointers can do damage if the eye is exposed to them directly for a length of time. Visual disturbances and sometimes damage of the retina or cornea can develop from exposure to a laser pointer. Though it may seem silly, eye protection may be necessary to avoid injuries that arise from exposure to laser pointers. There is nothing funny about loss of vision caused by 'playing' with a laser pointer, so handle them carefully and use them only as intended.

Proper eyewear can filter the laser wavelengths and protect the eye. Many places of work have banned laser pointers as being a hazard already, especially with children. Most authorities recommend that children not be allowed to play with laser pointers, as the risks far outweigh the fun. Many schools do not allow them to be used for this reason.

The message is one of safety. Protect your eyes and never look directly at the light from a laser pointer. Also be aware of the direction it is being pointed. Never point it toward other people. Point it only at the graph or chart. If it is not needed at a particular point, point it at the ceiling or, better yet, turn it off. There are relatively low incidences of adults sustaining permanent injuries from laser pointers, but it is a possibility, especially when using the more high-powered lasers.

So be careful and if necessary, use protection. Follow all the safety precautions listed in the instructions that accompanied the laser pointer. Your eyes will thank you.
