Impairments or conditions in which binocular visual skills are dysfunctional and the eyes are unable to align properly. Humans, like all mammals, have true binocular vision. This means that, in health, the two eyes of an individual normally move in a very coordinated fashion and the images formed by the right and left eyes are combined into a single binocular perception of the world. In contrast, when an individual's two eyes do not work together, binocular vision is impaired (Fig. 1). See also: Eye (vertebrate); Eye disorders; Perception; Vision; Visual impairment
