High Eye Pressure: What It Means and How to Lower It
If a doctor tells you your eyes have high pressure, you might wonder if that’s serious. High eye pressure, also called ocular hypertension, is when the fluid inside the eye pushes harder against the walls than normal. It doesn’t always cause symptoms, but over time it can damage the optic nerve and lead to glaucoma – a leading cause of blindness.
What Causes High Eye Pressure?
The eye constantly produces fluid (aqueous humor) that drains through tiny channels. When drainage slows or production spikes, pressure rises. Common culprits include family history, age over 40, diabetes, and certain medications like steroids. Even a short‑term spike after an eye injury can raise the numbers.
How Doctors Check Your Pressure
An eye exam includes a quick test called tonometry. The doctor uses a small puff of air or a gentle probe to measure the pressure in millimeters of mercury (mmHg). Normal range sits between 10 and 21 mmHg. Anything above that flags ocular hypertension, prompting closer monitoring.
Because high eye pressure often has no warning signs, regular check‑ups are key. If you’re over 40 or have a family member with glaucoma, ask your eye doctor to test your pressure at least once a year.
Practical Ways to Lower Pressure
Lifestyle tweaks can help keep the numbers down. Exercise regularly – walking, swimming, or biking improves blood flow and can lower eye pressure modestly. Keep caffeine intake moderate; too much coffee may cause short spikes. Eating a diet rich in leafy greens, carrots, and omega‑3 fatty acids supports overall eye health.
If you’re on steroid eye drops for allergies or inflammation, talk to your doctor about alternatives. Some people benefit from prescription eye drops that improve fluid drainage, such as prostaglandin analogs or beta blockers. Never start or stop medication without professional guidance.
When to Seek Help
\nIf you notice vision changes – like halos around lights, peripheral loss of sight, or sudden eye pain – get medical attention right away. These could signal that high pressure is already harming the optic nerve.
Remember, catching ocular hypertension early gives you a better chance to prevent glaucoma. Simple steps like regular exams, healthy habits, and following your doctor’s advice can protect your vision for years to come.
