What could happen if a person looks directly into a black light?

• A. Permanent eye damage
• B. It will possibly cloud the vision of the person looking into the light for a short period of time
• C. It will improve night vision
• D. It has no effect

Answer: (B)

Looking at a black light can cause a temporary disturbance in vision because it emits ultraviolet light that can irritate the surface of the eye. The UV exposure can lead to a short-term clouding or haziness as the eye responds to the light, often with temporary blur or discomfort. This effect is usually transient and not permanent with brief exposure, unlike longer or more intense UV exposure which can be more serious. UV light doesn’t improve night vision, and there is an actual effect from looking directly at it, so it’s best to avoid staring into bright UV sources.
