Eye pressure is a vital component in the overall health of the eye and can be an indicator of ocular disease. In healthy individuals, normal ocular pressure can range from 12 to 22 mm Hg. If ocular pressure is above 22 mm Hg, it is considered high. Ocular hypertension, as high eye pressure is known, is considered a strong risk factor for glaucoma and can cause permanent damage to the eye. Eye pressure can be influenced by a variety of factors including diet, exercise, genetics and age.
