Double Vision (Diplopia)

Double vision is also called diplopia, which causes a person to see two images of a single object. Diplopia is the medical term for double vision. It is the simultaneous perception of two images of a single object and the displacement may be horizontally, vertically or diagonally. Double vision is one of the most troublesome visual disorders a patient can experience. Double vision can be due to the result of impairment in any part of the vision system, including the cornea, eye muscles, lens, nerves, or the brain. It usually occurs when the eyes, that are previously worked together as a pair, is no longer able to do so because a squint has developed and the eyes are now out of alignment with each other, resulting in double vision and this may happen suddenly or over a period of time. Double vision is a symptom of strabismus.

Causes of Double Vision or Diplopia:

Misalignment of the two eyes due to functional problems in the visual system

A structural defect in the eye's optical system

Cornea problems

Nerve problems
