Some cases of headaches and pain behind the eyes are symptoms of uncorrected vision issues. Eye strain can commonly occur from staring at a television or computer screen — or even undiagnosed nearsightedness. This causes the brain and eye to make up for vision impairment, often resulting in a headache. Other eye conditions that could cause headache and pain behind the eye include optic neuritis, or inflammation of the optic nerve, glaucoma, an eye disease affecting the optic nerve, intermittent angle closure glaucoma, idiopathic intracranial hypertension, and giant cell arteritis. For headache and pain behind the eyes, it is suggested to get your vision checked and get vision correction, if needed.
