visual impairment in which an object is seen as two objects; "diplopia often disappears when one eye is covered"
Double vision, or the simultaneous awareness of two images of the same object that results from a failure of the two eye to work in a coordinated fashion Covering one eye will erase one of the images
Also known as double-vision Each eye sees the same object, but projects two images to the brain
A condition in which a single object is perceived as two; also called double vision Usually with both eyes open as in binocular diplopia, but can be with only one eye as in monocular diplopia
