You can only know for sure if your eye pressure is normal by having it measured by an eye care professional. While you can't feel your eye pressure, knowing the typical ranges and potential risks is helpful.
Normal eye pressure, also known as intraocular pressure (IOP), is generally considered to be between 10 and 20 millimeters of mercury (mmHg), according to the American Academy of Ophthalmology.
Here’s a breakdown to help you understand:
-
The Only Reliable Way: A comprehensive eye exam performed by an optometrist or ophthalmologist is the only way to accurately determine your eye pressure. This involves a test called tonometry.
-
Normal Range: As the American Academy of Ophthalmology indicates, pressures between 10 and 20 mmHg are typically considered within the normal range.
-
High Eye Pressure (Ocular Hypertension): Elevated eye pressure (above 20 mmHg) without any other signs of glaucoma is called ocular hypertension. The American Academy of Ophthalmology points out that elevated eye pressure, even without symptoms, is a concern. It needs monitoring to prevent potential damage to the optic nerve and vision loss.
-
Low Eye Pressure (Hypotony): Although less common, eye pressure that's too low can also cause vision problems and requires medical attention.
Why is it important to know your eye pressure?
-
Glaucoma Risk: High eye pressure is a significant risk factor for glaucoma, a leading cause of irreversible blindness.
-
Vision Protection: Monitoring your eye pressure helps your eye doctor assess your risk and determine if treatment is needed to protect your vision.
| Eye Pressure Category | mmHg Range | Significance |
|---|---|---|
| Normal | 10-20 mmHg | Generally considered healthy, but regular check-ups are still important. |
| Ocular Hypertension | Above 20 mmHg | Elevated risk of glaucoma; requires monitoring. |
| Hypotony (Low Eye Pressure) | Below 10 mmHg | Can indicate other eye problems and needs evaluation. |
In summary, because there are no outward symptoms, regular eye exams are essential to ensure your eye pressure is within the normal range and to detect any potential problems early.
