Never point the laser at the ____ or _____.

• A. Eye, Reflective Surfaces
• B. Eyes, Ears
• C. Hands, Shoes
• D. People, Animals

Answer: (A)

Laser safety centers on protecting vision and preventing accidental exposure from reflections. Never point a laser at the eyes or at reflective surfaces. The eyes are highly sensitive to laser light; even a brief direct hit can burn the retina and cause permanent vision loss. Reflections from shiny surfaces can bounce the beam into someone’s eyes or into other spaces in unpredictable ways, and some lasers produce light that isn’t visible, so you might not even realize the beam is traveling toward someone until it’s too late. These two hazards—eye injury and dangerous reflections—are the primary safety concerns, which is why this option is the best. Other choices don’t address the critical risks to vision or the danger posed by reflections.
