Medical records at a large university Headache Centre revealed that only 1% of headaches were caused by eye problems.

• In most cases headaches are caused by tension, anxiety, conflict and unresolved emotional problems. These headaches tend to be in the back of the head, the neck or both temples. Fatigue or alcohol make them worse.
• A headache in the top of the head may be due to uncontrolled high blood pressure.
• Headache across the forehead may be due to allergies, especially to foods.
• Sinus headaches can be due to pollen allergies, flu, colds, and sinusitis.
• A migraine usually occurs on one side of the skull. It may last for several days and be accompanied by nausea and vomiting.
• A headache similar to migraine, but occurring in one eye and the side of the nose and adjacent sinus is called “Horton’s histamine headache”. It may be of emotional origin.

If you are suffering with migraine, histamine headache or chronic headache you should be evaluated by a neurologist. There are new medication available for these conditions. The eye problems that cause headaches are:

• glasses too strong in minus power
• incorrect astigmatism correction
• eye muscle imbalance
• unequal optical centres
• eye fatique and rarely glaucoma.

Except for the last two, most of these problems are solved with proper eyeglasses.
