Suppression of an eye is a subconscious adaptation by a person's brain to eliminate the symptoms of disorders of binocular vision such as strabismus, convergence insufficiency and aniseikonia. The brain can eliminate double vision by ignoring all or part of the image of one of the eyes.
One light: If the patient sees one light, that means that either they have fused the two images from each eye together, or are suppressing of one of the images. Two lights: If the patient sees two lights, this is indicative of diplopia as the patient has an image from each eye but is unable to fuse the two.
Binocular vision anomalies include: diplopia (double vision), visual confusion (the perception of two different images superimposed onto the same space), suppression (where the brain ignores all or part of one eye's visual field), horror fusionis (an active avoidance of fusion by eye misalignment), and anomalous retinal correspondence (where ...
Ocular dominance, sometimes called eye preference or eyedness, [1] is the tendency to prefer visual input from one eye to the other. [2] It is somewhat analogous to the laterality of right- or left- handedness ; however, the side of the dominant eye and the dominant hand do not always match. [ 3 ]

Given that an observer has a certain fixation disparity and suffers from eye strain, one may consider some of the following ways of remediation. Eye glasses with an included prism power is the optical method to reduce a fixation disparity. Different procedures have been proposed to determine the required amount of prism for the individual ...
