Diplopia, or double vision, is the sensation of seeing 2 copies of a viewed object. It may arise because of disturbed optical elements within the eye or disturbed cerebral processing of visual information (monocular diplopia). More commonly, it is the result of ocular misalignment (binocular diplopia).
