Do I need glasses for double vision?

Answer: 

Double vision, also known as diplopia, is caused by a number of factors and the treatment will largely depend on the cause of the condition. The double vision can be horizontal (side by side), vertical (images appear on top of one another) or oblique (a combination of the two). Glasses are a common form of vision correction for diplopia.

The first step to correct treatment is determining whether the double vision occurs in just one eye (monocular), or both eyes (binocular). If the underlying cause differs for each eye, they will likely need to be treated separately. Problems can occur in the cornea, the lens, the muscles of the eye, nerves leading to the brain, or even the brain itself. Any one of these can cause double vision.

In the cornea, there could be an abnormality which distorts the light coming in, leading to double vision. This can come from an infection in the cornea, a scar or even dryness.In the lens, cataracts are often the reason behind double vision. Minor surgery is often a way of dealing with this issue by removing cataracts.If the cause is in the muscles of the eye, it can often mean that one eye does not move as well as the healthy eye, which might appear as diplopia.Monocular double vision can be caused by astigmatism, a condition where the cornea is curved abnormally.

Glasses are a common form of treatment for this issue.Many of these issues are dealt with by a prescription for eyewear, however some of the issues, such as those caused by problems in the nerve or brain may take a more serious approach. The best course of action is to start with an accurate diagnosis of just where the problem is in the eye structure and what the condition is before looking at treatment options.  It is best to consult your optometrist or eye specialist, if you are experiencing double vision.
