Fixation disparity is a tendency of the eyes to drift in the direction of the heterophoria.While the heterophoria refers to a fusion-free vergence state, the fixation disparity refers to a small misalignment of the visual axes when both eyes are open in an observer with normal fusion and binocular vision. The misalignment may be vertical, horizontal or both.

Co je to Vergence? Vergence je současný pohyb obou očí v opačných směrech, aby si osoba udržovala vizuální vnímání objektu. V zásadě to znamená, že oči se budou pohybovat ve směru k objektu a zamknou na ni střed žáků. Tím je objekt neustále zaostřen, což umožňuje osobě s ním udržovat vizuální kontakt.
