The stripe paradox.

An account is given of a phenomenon of binocular vision called here ‘The Stripe Paradox’. The name refers to a peculiar property exhibited by a set of stripes: that of resisting all attempt to produce double-imagery regardless of their positioning relative to the two optic axes. An investigation designed to ascertain the limits within which the effect operates is here described and some attempt is made at an explanation of the phenomenon in terms of certain known visual mechanisms.
