It’s often said the brain is an extension of the eye, and for that reason a headache may be a symptom of an vision problem.  Headaches that are related to the eye can be of the forehead, temples, behind the eyes, and at the back of the skull. They may be excruciating or dull. They may or not be alleviated by Tylenol or sleep. They may even present with blurred vision.

If you are having headaches with blurry vision, your eye doctor may ask you the following questions:

• Where do your headaches occur?
• Do you wake up with headaches? Do they worsen with near work?
• How long does your vision stay blurry when you have the headache?
• If you were to grade the severity of the headache on a 1-10 scale, what number would you give?

Here are the 8 most common reasons for headaches combined with blurry vision, and how they are diagnosed and treated.
