Your Care Instructions

Double vision means seeing two images instead of one. To see normally, your eyes, the muscles that move them, the nerves that send images to your brain, and your brain all have to work together. A problem with any of these parts can cause double vision.

Double vision can occur in one or both eyes. It can be horizontal (so the images appear side by side) or vertical (so one image appears above the other).

Double vision may be caused by a muscle or nerve problem. Or it may be caused by an eye problem such as a cataract or by a brain problem such as a stroke. When the cause is found, double vision can usually be corrected.

To find the cause, you may need tests. These may include blood tests and imaging tests such as MRI. You may need to follow up with an eye doctor or a brain specialist (neurologist) for more testing or treatment.

The doctor has checked you carefully, but problems can develop later. If you notice any problems or new symptoms, get medical treatment right away.

How can you care for yourself at home?

• Do not drive or do other things that could be dangerous because of your double vision.
• Make your home safe to help prevent injuries. For example, remove throw rugs and electrical cords that could cause falls. Be extra careful when you work with sharp tools or knives.
• Ask another adult to stay with you until your vision gets better.
