Laser Pointers May Harm Eyes

by Berkeley Wellness  |  

Avoid eye injury from laser pointers, which are often used at work and school. In particular, avoid high-powered lasers sold on the Internet, which may exceed FDA limits for consumer use.

Never aim the device at another person or a pet (cats love to chase the light), and never look into the beam. Don’t allow children to use the pointers unless supervised.

There have been reports of serious eye injuries, crashes caused by drivers temporarily blinded by pointers, and thousands of incidents of lasers pointed at aircraft. Green lasers are particularly hazardous, according to recent research.

When buying a laser pointer, choose one labeled Class I, II, or IIIa, with a maximum output of 5 milliwatts, and a statement of compliance with Chapter 21 of the Code of Federal Regulations (21 CFR 1040).
