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.
