Strabismus – or “crossed eyes” – is a condition where a person cannot correctly align both of his/her eyes – one or both eyes turn up, down, in or out. To correct for the double vision that results from this, people with strabismus often “suppress” the visual input from one of the eyes, causing the non-suppressed eye being stronger than the suppressed one.
