Per Wikipedia …
Strabismus, also called crossed eyes, is a condition in which the eyes do not properly align with each other when looking at an object. Exotropia is a form of strabismus where the eyes are deviated outward.
The brain’s ability to see three-dimensional objects depends on proper alignment of the eyes. When both eyes are properly aligned and aimed at the same target, the visual portion of the brain fuses the forms into a single image. When one eye turns inward, outward, upward, or downward, two different pictures are sent to the brain. This causes loss of depth perception and binocular vision.
Strabismus occurs in about 2% of children.
