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:
“Love, love, love—all the wretched cant of it, masking egotism, lust, masochism, fantasy under a mythology of sentimental postures, a welter of self-induced miseries and joys, blinding and masking the essential personalities in the frozen gestures of courtship, in the kissing and the dating and the desire, the compliments and the quarrels which vivify its barrenness.”
—Germaine Greer (b. 1939)
