People blink their eyes tens of thousands of times every day. Scientists have long believed blinking was an involuntary movement and served mainly to keep the eyeballs wet. But a new study suggests it has a more important purpose. An international team of scientists studied the blinking of human eyelids. The team reported to researchers from the University of California at Berkeley. The journal Current Biology published their findings. The team said it found that blinking “repositions our eyeballs so we can stay focused” on what we are seeing. It said that when we blink our eyelids, the eyes roll back into their sockets -- the bony area that surrounds and protects the eyes. However, the researchers found the eyes don’t always return to the same position. They say this causes the brain to tell the eye muscles to “realign” our eyesight.
