My optician said I have high eye pressure. What does this mean?

Rule out glaucoma. Eye pressure normally runs between 10 and 20mmhg (milimeters of mercury). If the pressure runs higher, eye doctors want to evaluate if there is an underlying cause for it, such as glaucoma. Other factors can cause the pressure to appear high, such as a thick cornea or excessive squeezing during the test. Have a full dilated eye examination soon.
Glaucoma. It may indicate you have glaucoma. See eye professional skilled in glaucoma management.
See an eyeMD. High eye pressure can be a false reading. It can also mean ocular hypertension/glaucoma suspect. Thus it's best to obtain a complete eye exam to evaluate for glaucoma.
