Why Do Humans Blink So Much? New Research Challenges Traditional Views

Researchers from the University of Rochester have found that blinking does more than keep our eyes moist; it likewise boosts visual processing by changing the light patterns gotten by the retina, thus providing a different kind of visual signal that helps our brain perceive the big image more effectively. On average, humans spend about 3 to 8 percent of their waking hours with their eyes closed due to blinking.Given that blinks prevent an image of the external scene from forming on the retina, its a strange peculiarity of advancement that we invest so much time in this relatively susceptible state– specifically thinking about that eye blinks happen more regularly than necessary simply to keep our eyes well lubricated.So why is blinking important?Researchers from the University of Rochester examined the curious case of blinking and discovered that eye blinks arent simply a mechanism to keep our eyes moist; blinks also play an essential function in permitting our brains to process visual details.”By regulating the visual input to the retina, blinks effectively reformat visual details, yielding luminance signals that differ dramatically from those usually experienced when we look at a point in the scene,” states Michele Rucci, a professor in the Department of Brain and Cognitive Sciences.The big photo– in the blink of an eyeRucci and his coworkers tracked eye motions in human observers and combined this data with computer models and spectral analysis– examining the various frequencies in visual stimuli– to study how blinking affects what the eyes see compared to when the eyelids are closed.The researchers measured how delicate people are at viewing different types of stimuli, such as patterns at different levels of details.

Scientists from the University of Rochester have actually discovered that blinking does more than keep our eyes moist; it likewise boosts visual processing by changing the light patterns received by the retina, consequently supplying a various kind of visual signal that helps our brain view the huge photo more successfully. On average, humans invest about 3 to 8 percent of their waking hours with their eyes closed due to blinking.Given that blinks prevent an image of the external scene from forming on the retina, its a strange quirk of development that we invest so much time in this apparently vulnerable state– especially thinking about that eye blinks happen more regularly than essential just to keep our eyes well lubricated.So why is blinking important?Researchers from the University of Rochester examined the curious case of blinking and discovered that eye blinks arent simply a system to keep our eyes moist; blinks likewise play a crucial function in enabling our brains to process visual information.”By regulating the visual input to the retina, blinks efficiently reformat visual information, yielding luminance signals that vary dramatically from those normally experienced when we look at a point in the scene,” states Michele Rucci, a professor in the Department of Brain and Cognitive Sciences.The huge photo– in the blink of an eyeRucci and his coworkers tracked eye movements in human observers and integrated this data with computer system designs and spectral analysis– analyzing the different frequencies in visual stimuli– to study how blinking impacts what the eyes see compared to when the eyelids are closed.The researchers determined how delicate people are at perceiving various types of stimuli, such as patterns at different levels of information.
