Every few seconds, our eyelids automatically shutter and our eyeballs roll back in their sockets. So why doesn't blinking plunge us into intermittent darkness and light? New research, shows that the brain works extra hard to stabilize our vision despite our fluttering eyes according to Science daily.
Scientists have found that blinking does more than lubricate dry eyes and protect them from irritants. In a study, they found that when we blink, our brain repositions our eyeballs so we can stay focused on what we're viewing.
