Double vision in one eye is known as monocular double vision. Double vision continues when the unaffected eye is covered, but you should be able to see normally when the affected eye is covered.
It can be caused by:
an irregularly shaped cornea (astigmatism), which is a refractive error
dry eye, which is when your eye does not produce enough tears
abnormalities of the cornea
abnormalities of the lens, such as cataracts (cloudy patches over the lens)
abnormalities of the retina, such as macular degeneration
The cornea is located at the front of the eye and acts like a camera lens, helping to focus the light coming into the eye.
The retina is a light-sensitive layer of tissue at the back of the eye that converts light entering the eye into electrical signals.
Double vision caused by both eyes failing to work together properly is known as binocular double vision. If you have binocular double vision, your vision will usually be normal if either eye is covered.
If you have binocular double vision, your eyes will point at slightly different angles, causing them to send different images to your brain. The images from each eye are too different for your brain to create a clear, single image. This results in you seeing double images.
