Scientists at the University of Queensland has discovered the actual truth behind motion-induced blindness. This is a form of visual illusion in which moving objects make stationary objects vanish right in front of our eyes.
Previously experts believed that it was a failure our visionary system. They held brain responsible for this mistake.
But recent findings suggest that it is a trick played by the brain to help us see moving objects clearly. The study has been reported in the journal Current Biology.
Actually, a vast portion of our brain concentrates on visual input. When we see something the image reaches our brain for interpretation. The interesting part is that our eye is like a camera with slow shutter speed. Hence it creates streaks when we view moving objects. This confuses our brain.
So in such a situation, in order to assure crystal cut visibility of moving objects, brain literally rubs off the stationary ones. This is definitely not blindness, its just a helpful act on the part of brain to improve vision quality.
