5 Main Causes of Double Vision

Eye Muscles

Your eyes are controlled by six muscles that is movement. Defects in these muscles may result in the development of double vision. Paralysis or weakness in any of these muscles may prevent them from working in sync.

Graves’ disease [2] or thyroid eye disease is an autoimmune inflammatory disease that affects the tissues in the eye socket. Graves’ disease causes vertical double vision.

Strabismus is another well-known condition responsible for double vision in some people. Strabismus is often externally noticeable and is the result of weak or paralyzed eye muscles preventing the normal alignment of the two eyes. One eye may go in the opposite direction from the other.

Most people with strabismus are born with it, but not all of them eventually develop double vision. The brain usually copes by ignoring information from one eye, in what is known as suppression. This often leads to the development of lazy eyes.
