Researchers previously believed contrast sensitivity function -- the minimum level of black and white that a person needs to detect a pattern -- was mainly dictated by the optics of the eye and processing in the brain. Now researchers explain that there is another factor at play: contrast sensitivity also depends on small eye movements that a person is not even aware of making.
