The Purpose of Blinking: More Than Just Eye Moisture

As a common, automatic function of the body, blinking plays a significant role in visual perception. The average person blinks their eyes about 15-20 times per minute while awake, which helps remove dust and debris from the eyes, preventing inflammation and injuries. It also lubricates the eyes to improve vision.

Researchers at the University of Rochester observed that blinking takes up approximately eight percent of our waking time. They concluded that it must serve an evolutionary purpose because it interrupts visual perception and affects how the brain processes information. However, a recent study published in PNAS found that blinking actually enhances rather than interferes with the processing of visual information in the brain. Rapid blinking changes light patterns that reach the retina, sending different signals to the brain than when our eyes are open.

The study showed that these signals help the brain get a “big picture” of a phenomenon or coincidence, making it easier to detect patterns that change slowly. Blinking is thus an essential part of our brain’s machinery for perception and helps us adapt to changing visual stimuli efficiently. Studying its effects on vision is helping researchers gain a better understanding of how our brains process visual information and adjust to interruptions in visual input.
