Retinal disparity: The image of the object which falls on both the retinas differs. Fixation disparity testing at near using the Wesson fixation disparity card showed a right hyper fixation disparity of 4.3 minutes of arc. Binocular viewing of a scene creates two slightly different images of the scene in the two eyes due to the eyes' different positions on the head. Central fixation disparity (a small misalignment of the eyes when viewing with binocular vision) First, the neurolens Measurement Device measures pupillary distance. Other binocular cues include: Retinal disparity: Retinal disparity simply means that each eye receives a slightly different image due to the different angle from which each eye views an object.

Stereopsis is a critical component of human vision and is a visual trait shared by animals with front-facing eyes.
