A new study published online in the journal Current Biology found an intelligent reason for why we blink.
It shows that blinking “prompts eye muscles to keep our vision in line.”
An article in Science Daily gives us some details:
“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 led by the University of California, Berkeley, shows that the brain works extra hard to stabilize our vision despite our fluttering eyes.
Scientists at UC Berkeley, Nanyang Technological University in Singapore, Université Paris Descartes and Dartmouth College have found that blinking does more than lubricate dry eyes and protect them from irritants.”
Science Daily discloses what else happens:
“Our brain repositions our eyeballs so we can stay focused on what we're viewing…
When our eyeballs roll back in their sockets during a blink, they don't always return to the same spot when we reopen our eyes. This misalignment prompts the brain to activate the eye muscles to realign our vision, said study lead author Gerrit Maus, an assistant professor of psychology at Nanyang Technological University in Singapore.”
Everything is done for a purpose. Intelligent communication prompts our eyes to make the necessary corrections so we continue seeing.
Without this “powerful oculomotor mechanism … our surroundings would appear shadowy, erratic and jittery.”
They don’t. This is powerful evidence for intelligent design.
