Double Vision – Seeing Double – Causes of Diplopia

What is Diplopia?

Diplopia is also known as Double Vision. It occurs when an individual sees 2 or more images of the same object. Diplopia is different from the blurred vision where a single object appears to be unclear.

The vision in humans is single Binocular vision. This means that the images from both the Eyes are recorded and processed by the Nervous System but it makes a single image. An interruption in this process can make a double vision.

The double vision may be present in 1 Eye known as Monocular or 2 images can be made from both the Eyes together known as Binocular.
