Headaches Headaches Definition Symptoms Treatment Clinic Information Definition Headache is one of our most common health complaints. Most headaches are not usually serious, and are often caused by tension.
Some people believe that many headaches are caused by improper eyeglasses causing eyestrain.
Almost all headaches are made worse by lengthy use of the eyes, but those that are caused by eyestrain appear only when you have used your eyes for a long period of time. Because headaches often produce symptoms which suggest that the eyes are at fault, many people who suffer from chronic headaches feel the need to have their eyes examined. Your ophthalmologist can be of help in diagnosing the cause of headache, even though headaches are infrequently caused by eye disease or the need for glasses. Muscle contraction headaches are by far the most common type. The pain comes from the pulling of muscles in the neck and at the base of the head.
