Do You Have a Corneal Disorder or Double Vision?

People with double vision, or diplopia, frequently perceive two identical images. Strabismus, characterized by misaligned eyes, can cause unpleasant double vision but is otherwise safe.

How do you explain double vision?

Each of your eyes creates its unique view of the world. The brain takes in data from both eyes and creates a composite image.  The use of both eyes together generates depth perception. Damage to the ocular muscles or the nerves that control eye movement can lead to double vision.  It’s also possible that double vision is caused by a condition that weakens the eye-moving muscles.

Monocular diplopia may have these potential causes:

Cataract, which typically affects those above the age of 80

  • Surface irregularity or a distorted corneal shape (such as in keratoconus)
  • Astigmatism (refractive errors)
  • Eyes that are so dry that blinking causes irritation and discomfort
  • Traumatic lens dislocation, in which the lens of the eye is dislodged
  • Pterygium (thickening of eye mucous membrane)
  • Polycoria

What are the Drawbacks of Experiencing Double Vision?

  • The risk of complications arises from whatever is causing the double vision.
  • The causes of dual vision range from the simple (like an allergy) to the complex (like a persistent illness).
  • Some patients with double vision report feeling sick or dizzy due to the shift in their visual field.
  • Others may have trouble focusing due to increased sensitivity to light or sound.
  • While infections and brain tumors are extremely rare causes of double vision, they are nonetheless possible.
  • Many people with diplopia suffer from severe eye pain, altered vision, and headaches. Any headache accompanied by a modified image is potentially fatal and should be evaluated immediately.

The Diagnosis and Treatment of Double Vision:

Distinguishing between monocular and binocular double vision is typically straightforward. However, pinpointing the root of the problem may prove more difficult. You can determine if you have a double vision based on your symptoms and how you perceive things visually.

What’s the Deal with Double Vision?

Avoiding the onset of those issues is the key to avoiding double vision.

Some advice is as follows:

  • You are taking control of diabetes. If you have diabetes and take your medication as prescribed, you will greatly lower your chances of double vision. People who eat healthily and exercise regularly are much less likely to get double vision due to diabetes.
  • Avoiding cataracts is a must. Sunglasses, giving up cigarettes, and a nutritious diet may all contribute to maintaining good eye health and warding off cataracts.
  • It helps relieve dry eyes. Avoid getting computer-related eye strain whenever possible. This could exacerbate dry eye symptoms.
  • Avoid concussions at all costs. Always use safety precautions such as fastening seatbelts, donning helmets, carrying weapons, etc.


After a while, people who experience double vision can normally see again. Some individuals may fully recover with minimal treatment, depending on the underlying cause. After removing the root cause, you should no longer have double vision or other symptoms.
