A laser pointer contains a small diode
laser that emits an intense beam of light. Most laser pointers contain
low to moderate powered lasers that do not pose a serious risk of eye injury
unless intentionally misused. Some of the newer laser pointers, especially
the green light pointers, present a significantly increased risk of eye
Direct viewing of the laser beam may
cause temporary flash blindness, headaches, afterimages or glare. Besides
the risk of injury from the beam, the outrage from being exposed or loss
of concentration may promote other hazards.
The following safety considerations should be observed when using laser pointers:
Never look directly into the laser beam.
Never point a laser at a person.
Do not aim the laser at a highly reflective
Only use laser pointers that have.
