what is good eye pressure
Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 10 to 21 mm Hg. When a person's pressure is higher than 21 mm Hg, they are at an increased risk for developing glaucoma. Some people can tolerate pressures slightly higher than normal without developing glaucoma.ormal eye pressure ranges from 10 to 21 mm Hg.
