Your eyes blink about 15–20 times per minute — but why does blinking not constantly interrupt your vision, creating a flickering effect like a camera shutter?
A
The brain fills in the gap using the image it already has stored
B
Blinking is too fast for the eye to register any darkness
C
The eyelid is partially transparent, letting light through
D
The brain actively suppresses visual processing during each blink
E
The pupils dilate rapidly to compensate for the brief closure
