Do cataracts cause double vision?

Most "double vision" (diplopia) is caused by an imbalance between the muscles moving each eye somewhat differently. It disappears on covering one or the other eye. In certain situations, though, you can have what is called "monocular diplopia" or seeing two overlapping images in one eye by itself. Although this is not typical of cataracts, it is definitely one of the possible symptoms.
