  eMedicine - Diplopia : Article by Izak F Wessels, MBBCh, MMed, FRCSE, FRCOphth, FACS
Diplopia is a common subjective complaint, or it may be elicited during the course of the examination.
Physiologic diplopia is a normal phenomenon depending on the alignment of the ocular axes with the objects of regard (eg, focusing on a finger held close results in distant objects being blurry but double).
Monocular diplopia may occur from abnormal ocular media (eg, corneal distortion or scarring, multiple openings in the iris, cataract or subluxation of the natural lens or pseudophakic lens implant, vitreous abnormalities, retinal conditions).

  Diplopia - Wikipedia, the free encyclopedia
Diplopia, colloquially known as double vision, is the perception of two images from a single object.
It is in this way, that diplopia contributes to loss of depth perception and binocular vision, amblyopia (lazy eye), and/or strabismus (deviating eye).
Temporary diplopia can also be caused by intoxication from alcohol or head injuries, such as concussion.

 Diplopia
Diplopia is the medical term for seeing one object as two objects; it is also known as double vision.
The most common causes of diplopia are misalignment of the eyes (strabismus), damage to the nerves that control the eye muscles, astigmatism, keratoconus, dry eyes, retina damage, diabetes, myasthenia gravis (a neuromuscular illness), Graves’ disease (autoimmune hyperthyroidism) and trauma.

 Diabetes Monitor - mononeuropathy and diplopia
The third, fourth, and sixth cranial nerves control the extra-ocular muscles (EOM) of the eyes, allowing the eyeball to rotate in different directions.
So, if one of the these nerves is damaged on one side, the eye on that same side can't fully move, causing double vision (diplopia, from the Greek, diplous=double + ope=sight) when the patient looks in certain directions.
This double vision is extremely annoying, but easily temporarily treated, by putting a patch over the eye on the side where the nerve is affected.
