Also known as Diplopia and Seeing double
Diplopia, commonly known as double vision, is the simultaneous perception of two images of a single object that may be displaced horizontally, vertically, or diagonally (i.e. both vertically and horizontally) in relation to each other. It is usually the result of impaired function of the extraocular muscles (EOMs), where both eyes are still functional but they cannot converge to target the desired object. Problems with EOMs may be due to mechanical problems, disorders of the neuromuscular junction, disorders of the cranial nerves (III, IV, and VI) that stimulate the muscles, and occasionally disorders involving the supranuclear oculomotor pathways or ingestion of toxins.Source: Wikipedia
The most common causes of double vision are cataract, cranial nerve palsy, and eye alignment disorder. Other possible causes, such as chronic glaucoma, are more rare.
Within all the people who go to their doctor with double vision, 57% report having diminished vision, 50% report having headache, and 41% report having dizziness.
Patients with double vision often receive x-ray computed tomography, electrocardiogram, kidney function tests, cat scan of head, magnetic resonance imaging, cardiac monitoring, cardiac enzymes measurement and ophthalmic examination and evaluation .

The most commonly prescribed drugs for patients with double vision include pyridostigmine (mestinon), tropicamide ophthalmic, phenylephrine (duramax), dexamethasone-tobramycin ophthalmic, timolol, brimonidine ophthalmic, pseudoephedrine / triprolidine, indapamide, cyclopentolate ophthalmic, glatiramer (copaxone), azathioprine, amlodipine / atorvastatin and hydrochlorothiazide / irbesartan .
Groups of people at highest risk for double vision include age 75+ years age 60-74 years. On the other hand, age < 1 years almost never get double vision.
