amblyopia
noun
am·bly·opia
ˌam-blē-ˈō-pē-ə 
: reduced vision typically in one eye that results from the brain suppressing input from the affected eye due to unequal visual signals from each eye (as from strabismus or anisometropia) leading to poor development of visual acuity in the affected eye
Sometimes the misalignment produces double vision. In such cases the brain's solution is to suppress the input from one eye. Eventually this input will wither, and the vision from that eye will become permanently poor—a condition called amblyopia …—
