diplopia

A condition where a single object is perceived as two separate images instead of one. Homonymous diplopia occurs when the image seen by the right eye is to the right of the image seen by the left eye. Heteronymous diplopia occurs when the image seen by the right eye is to the left of the image seen by the left eye. It results from a disruption in binocular vision due to misalignment of the eyes or impaired fusion mechanisms.
