Saccadic masking, also known as visual saccadic suppression, is the phenomenon in visual perception where the brain selectively blocks visual processing during eye movements in such a way that neither the motion of the eye (and subsequent motion blur of the image) nor the gap in visual perception is noticeable to the viewer.
The phenomenon was first described by Erdmann and Dodge in 1898, when it was noticed during unrelated experiments that an observer could never see the motion of their own eyes. This can easily be duplicated by looking into a mirror, and looking from one eye to another. The eyes can never be observed in motion, yet an external observer clearly sees the motion of the eyes.

Famous quotes containing the word masking:
“We were that generation called “silent,” but we were silent neither, as some thought, because we shared the period’s official optimism nor, as others thought, because we feared its official repression. We were silent because the exhilaration of social action seemed to many of us just one more way of escaping the personal, of masking for a while that dread of the meaningless which was man’s fate.”
—Joan Didion (b. 1935)
