In the video by Doctor Eye Health titled What Causes Double Vision, the doctor discusses some of the causes of double vision. When you are driving and suddenly see two cars or your vision gets blurry, it may be a sign of a serious illness or you are sitting at work and seeing double when talking to a coworker, for example. If this occurs, you may want to visit an eye doctor to be evaluated for the causes. They have many tests that can determine what is causing blurry or double vision and what vision disorders you have.
Some of the causes are strabismus, a condition that causes the inner eye to turn inward or outward, causing double vision in patients. They have tests at the eye doctor for this and treatments available.
Thyroid eye disorder causes problems with your thyroid when the immune system attacks your muscles. It can attack the eye muscles, causing pain in the eyes, blurred vision, or double.
Often, an MRI is given to determine and treat this condition. Another autoimmune disorder that may cause double vision is myasthenia gravis, a disease that causes the autoimmune system to attack nerve signals that may control eye movements. Two serious conditions that may cause double vision are multiple sclerosis and a brain tumor. Both are evaluated with an MRI and treatment is available. Patients should have their eyes checked when experiencing frequent double vision as it may be a sign of a serious illness. There are many other vision disorders that can be the cause.
