The laser pointer: no demonstrated danger to the eyes

If laser pointers are powerful enough (> 5 mW), they can cause ocular damage. Most laser pointers in use, however, have low power, viz. 1 mW. In the peer-reviewed scientific literature worldwide not a single case of eye damage due to laser pointers is described. A review among Dutch ophthalmologists up to June 1998 revealed no cases of permanent damage caused by laser pointers. In view of the widespread use of laser pointers, the risk of retinal damage must be minimal, even with the types now banned. Laser pointers of 1 mW emitting light red or green light have sufficient visibility on projection screens. It is advisable to prohibit the sale of more powerful pointers to prevent excesses.
