Abstract

Blur, due to optical aberrations in the eye, has been implicated in visual illusions for converging line arrays. Using 26 illusion variants, 2.5 diopters of optical blur was optically induced, resulting in increased illusory effects for the Poggendorff and several Mueller-Lyer variants, but not for the other configurations. Some limitations on conditions drawn from induced blur are discussed.
