Which action helps improve night vision?

• A. Dim panel lights, and clean headlights/windshield
• B. Turn up dashboard brightness
• C. Do not use windshield wipers
• D. Wear sunglasses

Answer: (A)

Preserving night vision hinges on your eyes staying well adapted to darkness and your ability to see clearly with the light available. Dimming interior panel lights keeps stray light from hitting your eyes, so your pupils don’t constantly constrict and your retina remains more sensitive to dim road details. Cleaning the headlights and windshield reduces dirt, grime, and haze that scatter light and create glare, so the headlights shine more effectively and you have a clearer view through the windshield. Turning up dashboard brightness would add glare and disrupt night adaptation, making it harder to see in low light. Not using windshield wipers doesn’t improve visibility and is unsafe in rain or mist. Wearing sunglasses at night blocks light, reducing your ability to see contrasts and hazards.
