What Is Diplopia? Diplopia, or double vision, is a condition where a single object is seen in duplicate. Double and blurred vision are often thought to be the same, but they are not. In blurred vision, a single image seen by one eye appears unclear. Eyes wander or appear crossed or misaligned.
Double vision can result from impairment in any part of the vision system, including the cornea, eye muscles, lens, nerves, or the brain. The most common cause of diplopia is misalignment of the two eyes that can arise from several different conditions. Some diseases such as myasthenia gravis and Graves' disease can cause weakness of the eye muscles, leading to misalignment of the eyes and double vision.
