Glare recovery time is

• A. the time your eyes need to regain clear vision after being affected by glare
• B. the time it takes to blink
• C. the time it takes to recover from fatigue
• D. the time it takes to switch from high beams to low beams

Answer: (A)

Glare recovery time is the time your eyes need to regain clear vision after glare from bright light. When a sudden bright light, like an oncoming headlight, hits your eyes, the pupils and the eye’s light-sensing cells must readjust to a lower light level. That adjustment isn’t instantaneous, so your vision can remain dim or blurred for a moment even after the light passes. This is why nighttime glare can feel disorienting and why you should slow down and give more following distance when you’ve been exposed to strong glare. The other options describe blinking, fatigue recovery, or switching from high to low beams, which are separate concepts and do not describe how long vision lasts after glare.
