Seeing double can be much more than a troublesome visual issue. It can be a sign of a much greater problem. Since there are many potential causes for double vision, it is important to see an experienced eye care professional to sort out why this is happening.
This condition, also known as diplopia, occurs when the left and right eye are not working together properly. Overindulging in alcohol or excessive fatigue can cause this. In these cases it is temporary and vision should return to normal once the effects of the alcohol has worn off or the fatigue has been resolved with proper rest.
If the double vision persists for a longer period of time, it may be a sign of a larger problem. Some potential causes of this condition include:
- Graves Disease or Myasthenia Gravis
- Excessively dry eyes
- Head injury
- Brain tumor, swelling or aneurysm
- Refractive surgery
- Cranial nerve palsies
While some of the potential causes of double vision are easily corrected, others may need serious and ongoing medical treatment. If you are experiencing ongoing double vision, be sure to speak with a medical or eye care professional sooner rather than later to address any serious problems that this condition may signal.
