What is Double Vision (Diplopia)?
If you see two separate images of whatever you are looking at, you may have a condition known as diplopia, or double vision.
It is important to differentiate double vision from blurred vision. In blurred vision, a single image appears fuzzy or unclear. In binocular double vision, both eyes are healthy individually, but because they do not align and point at the same object, the brain receives two different pictures that it cannot merge, resulting in two distinct images.
"Most sudden-onset binocular double vision in adults is caused by microvascular cranial nerve palsies, frequently triggered by poorly controlled diabetes or hypertension."
Can Ignoring Double Vision Be Dangerous?
Yes. A sudden-onset squint or double vision can be a warning sign of serious, potentially life-threatening conditions, including:
- Raised intracranial pressure (increased pressure inside the skull).
- Brain tumors compressing ocular motor nerves.
- Aneurysms (ballooning of blood vessels in the brain).
- Stroke or transient ischemic attacks (TIAs).
* Urgent Warning: Any sudden-onset double vision requires immediate evaluation by a medical professional, preferably a neuro-ophthalmologist.
Treatment of Double Vision
Once serious neurological or life-threatening conditions have been ruled out, treatment of diplopia focuses on aligning the eyes and relieving symptoms:
- Prism Glasses: Special lenses that bend light entering the eye, shifting the images so that they merge together, eliminating double vision while the eye muscles heal.
- Eye Exercises: Tailored orthoptic exercises to strengthen weak eye muscles.
- Surgical Realignment: If double vision persists after 6 to 12 months (e.g. following nerve palsy recovery), squint surgery is performed to straighten the eyes permanently.

Frequently Asked Questions (FAQ)
What is double vision (diplopia)?
Double vision is seeing two images of a single object. It can be monocular (occurring in one eye when the other is closed) or binocular (occurring only when both eyes are open, pointing to misaligned eyes).
What causes binocular double vision?
Binocular double vision is usually caused by eye muscle weakness or cranial nerve palsies (3rd, 4th, or 6th nerve palsy) which disrupt the coordination between the two eyes. This can result from trauma, diabetes, stroke, or thyroid eye disease.
How is binocular double vision treated?
Treatments include specialized glasses with prism lenses to merge the double images, eye patching, vision therapy, Botox injections into eye muscles, or double vision corrective surgery (strabismus surgery).
