What is the term for double vision?

Diplopia is the medical term used to describe double vision, a condition where a person sees two images of a single object. This phenomenon can arise from various underlying issues, including problems with eye muscles, nerve damage, or issues within the brain itself. In contrast to other conditions, such as amblyopia, which refers to weak vision usually in one eye, or strabismus, which is the misalignment of the eyes, diplopia specifically pertains to the visual perception of two images. Presbyopia, on the other hand, relates to the age-related loss of near focusing ability. Thus, understanding diplopia is crucial for diagnosing and managing conditions associated with visual disturbances.
