In the interval of few seconds, our eyelids involuntarily blink and our eyeballs restore in their pouch. But have you ever thought, why doesn’t frequent blinking push us into sporadic darkness and light? Well, now a mutual study, conducted by a team of researcher from the UC Berkeley, Nanyang Technological University in Singapore, Dartmouth College and Université Paris Descartes has come up with the answer to this age-old question.
According to the new study, during the time, our eyes blink, the brain gives some extra effort to alleviate our visualization, which doesn’t let the blinking darkness and light occur. At the time, when our eyelids shutter, our brain to work quite harder for activating the realign of eye muscles, which in other ways helps the eye to avoid the partial darkness of light.
According to the reports, published in the online edition of the academic journal ‘Current Biology’, when we blink, our brain forces our eyeballs to be in motion so that we can remain alerted on what we are seeing during that particular time. At the point, when our eyeballs restore in their sockets throughout a blink, they don’t always go back to the same position when we reopen our eyes. This is a type of misalignment which instructs the brain to stimulate the eye physiques to realign our visualization, and hence after reopening eyes, we don’t just blackout,
As said by the lead author of the study, Gerrit Maus, who is also an assistant professor of psychology at Nanyang Technological University in Singapore, “The configuration of our eye muscles are quite slothful and vague, and hence the brain needs to continually transmit its signals to eyes, to ensure that our eyes are focusing on the exact thing, which we are viewing before blinking.”
During the research, the scientists found that the brain calculates the dissimilarity in what we view before and after winking, following which it instructs the eye muscles to rectifies if needed. In the study, the researchers involved more than a dozen of young adults. The lead author introduced the study as a postdoctoral fellow in Whitney Laboratory for Perception and Action, of the UC Berkeley.
