What Causes Double Vision?

Severe Migraines

Migraine headaches affect more than thirty-eight million individuals in the United States. This throbbing, painful headache can last up seventy-two hours. The origins of migraines are not completely understood, but studies point to changes in brain chemistry as well as cranial nerve issues. Because the double vision associated with severe migraines involves nerves rather than the physical structure of the eye, double vision will be seen with both eyes. For some individuals with migraines, double vision may be part of the migraine aura, a series of symptoms that happen in the pre-migraine stage. For others, double vision is part of the migraine experience itself, and as the headache ends, the double vision clears.
