Double Vision
Implications of blurred vision
Double vision, or diplopia, can be an indication of serious underlying physical health issues, and should always be treated seriously. While some causes of double can be relatively minor, others are not, and so it is important to get to the cause of the double vision if you experience it. Double vision is caused by problems in either a part of the eye – the cornea, the lens or the muscles around the eye – or in the nerves that carry visual messages to the brain. It can also be caused by problems in the part of the brain responsible for dealing with visual information.
Causes of Double Vision
Problems in the cornea can include an infection or an injury. In fact, those who have LASIK surgery performed on their eyes often complain of blurred vision after the surgery. Cataracts are the most common cause of lens-related problems that result in double vision. Muscle-related double vision problems are usually the result of muscles that have grown weak; however, there are some autoimmune diseases that attack the muscles around the eyes. Graves disease is another possible culprit.
Nerve damage that causes blurred vision can result from several causes, including multiple sclerosis, diabetes and other diseases. Finally, problems in the brain itself can be the result of stroke, aneurysm, tumors or migraines. Disruption of the vision centers in the brain is also a cause of double vision after head injury.
Double Vision Therapy Techniques
Double vision is treated various ways, depending on the underlying cause of the blurred vision, and any number of other factors.
Some people who experience chronic double vision, and thus have to cope with this as an ongoing issue, have found relief in vision therapy techniques that include various exercises designed to reduce the effects of blurred or double vision. These techniques have proved very helpful for adults as well as children who are in school and need to learn to read, a difficult task when vision is blurred or doubled. Check with your physician for more information on these techniques.
