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.
Diplopia also may result from failure of both eyes to point at the object being viewed, a condition referred to as ocular misalignment. In normal vision, both eyes look at the same object. The images seen by both eyes are fused into a single picture by the brain. If your eyes do not point at the same object, the image seen by each eye is different and cannot be fused. This results in double vision.
