Measuring Eye Pressure. Eye pressure is measured in millimeters of mercury (mm Hg). Normal eye pressure ranges from 12-22 mm Hg, and eye pressure of greater than 22 mm Hg is considered higher than normal. When the IOP is higher than normal but the person does not show signs of glaucoma, this is referred to as ocular hypertension. High eye pressure alone does not cause glaucoma.
But the inch is really not a unit of pressure, or force per area. It is a unit of length. So a metric unit has been defined to describe normal atmospheric pressure, called a bar, and the instrument becomes a barometer.. Actually, normal average sea-level pressure is 1.01325 bars, or 1,013.25 millibars (mb).The millibar is a commonly used unit of pressure.o a metric unit has been defined to describe normal atmospheric pressure, called a bar, and the instrument becomes a barometer..
