Patient discussion about duplication

Q. what is the cause for double vision

A. Double vision, or diplopia, as it's called, may be due to many conditions, including disorders of the muscles of the eye (extra-ocular muscles) and the nerves controlling them, disorders of the eye ball (enlarged eyeball as in Graves' ), and sometimes disorders of vision.

Diplopia may manifest important conditions, so consulting a doctor (e.g. neurologist or ophthalmologist) may be wise.
