If you get headaches regularly, one of the first things to do is to get your eyes checked. There’s a variety of eye problems that can cause headaches, including astigmatism, hyperopia (farsightedness), muscle misalignments, myopia (nearsightedness) and other more serious conditions such a glaucoma. In some cases, the headache is caused by the person squinting and overworking the eye muscles in an attempt to better focus their vision. In other cases, problems of internal pressure and swelling within the structures of the eye can ‘refer’ pain into other areas of the head. The location of the pain can give clues as to what the cause is. Headaches on the front or sides of the head are usually eye related. One at the back of the head, towards the shoulders is a tension headache. It’s important to get your eyes examined to eliminate your eyes as the cause, because even if vision is clear, eye muscle misalignments may result in headaches.
