Several approaches can help lower eye pressure, from prescription eye drops and laser procedures to lifestyle changes like regular exercise, dietary adjustments, and sleep positioning. Normal eye pressure falls between 10 and 20 mmHg, and the typical treatment goal is to reduce it by 20% to 30% from your baseline. What works best depends on how elevated your pressure is and whether you already have signs of glaucoma.
How Eye Pressure Works
Your eye constantly produces a clear fluid that nourishes its internal structures and maintains its shape. This fluid drains out through a tiny mesh-like channel near the front of the eye. When production and drainage are in balance, pressure stays in the normal range. Problems start when the drainage system becomes less efficient or the eye produces too much fluid, causing pressure to build. Sustained high pressure can damage the optic nerve, which is the connection between your eye and brain, leading to gradual vision loss known as glaucoma.
Elevated eye pressure without any nerve damage or vision changes is called ocular hypertension. It doesn’t always progress to glaucoma, but it’s the single biggest risk factor, which is why lowering it matters even before damage appears.
Prescription Eye Drops
Eye drops remain the most common first-line treatment. They work through two basic mechanisms: either reducing the amount of fluid your eye produces or opening up drainage pathways so fluid exits more efficiently.
Drops that improve drainage are often prescribed first. These are typically used once daily at bedtime and can lower eye pressure by 20% to 30%. They work by widening an alternative drainage route in the eye, and their effect lasts a full 24 hours. The other major category slows fluid production at the source. These are usually applied twice daily and have been among the most widely prescribed options for decades. Your eye doctor may combine both types, either as separate bottles or in a single combination drop, to get a bigger reduction than either achieves alone.
Laser Treatment
A quick, in-office laser procedure called selective laser trabeculoplasty (SLT) is now used as either a first option or an alternative when eye drops aren’t enough. The laser targets the eye’s natural drainage tissue, stimulating it to filter fluid more effectively. The procedure takes a few minutes, uses numbing drops, and most people return to normal activities the same day.
Success rates vary depending on how success is defined and how high your starting pressure is. In one two-year study, about 76% of patients who received SLT as a first-line treatment maintained meaningful improvement in drainage function. Patients with higher starting pressures tend to see more dramatic reductions. The effect can wear off over a few years, but the procedure can be repeated.
Aerobic Exercise
Regular aerobic activity is one of the most effective non-drug strategies for lowering eye pressure. Activities like brisk walking, cycling, jogging, and swimming all produce measurable drops. The mechanism likely involves improved blood flow and reduced stress hormones affecting fluid production in the eye.
The catch: the benefit only lasts as long as you keep exercising. Research shows that when people stop their exercise routine, eye pressure climbs back to pre-exercise levels within about three weeks. Consistency matters more than intensity. Aim for the kind of moderate cardio you can sustain several days a week rather than occasional intense sessions.
Diet and Leafy Greens
Dark leafy greens like spinach, kale, and arugula are rich in dietary nitrates, which your body converts into a molecule that relaxes blood vessels and improves circulation. Data from the Rotterdam Study found that for every additional 10 mg per day of nitrate from vegetables, the risk of developing open-angle glaucoma decreased by about 5%. That’s a modest but consistent effect, and it adds up if leafy greens are a regular part of your diet rather than an occasional side dish. A single cup of raw spinach contains roughly 30 to 50 mg of nitrate, so hitting meaningful intake levels doesn’t require dramatic dietary overhauls.
Supplements With Some Evidence
A combination supplement containing bilberry extract (160 mg) and French maritime pine bark extract (80 mg), sold under the brand name Mirtogenol, showed promising results in a small study of people with elevated eye pressure. After three months of daily use, average pressure dropped from 25.2 mmHg to 22.0 mmHg, and 19 out of 20 participants saw some reduction. That’s a meaningful drop, though the study was small and not placebo-controlled.
Saffron extract has also been tested. In a pilot trial, patients with open-angle glaucoma who took 30 mg of saffron extract daily alongside their regular eye drops saw their average pressure fall from 12.9 to 10.6 mmHg after four weeks, while the placebo group stayed essentially flat. Once they stopped taking saffron, pressure returned to baseline. These are early findings, not strong enough to replace standard treatment, but they suggest certain supplements may offer a modest additional benefit.
Sleep Position
Eye pressure naturally rises when you lie flat, which is why nighttime pressure spikes are a concern for people with glaucoma. Elevating the head of your bed by about 30 degrees lowers nocturnal eye pressure by roughly 3 mmHg compared to sleeping flat. That’s a clinically meaningful difference achieved without medication.
The method matters, though. Studies found that raising the head of the bed itself (using a wedge pillow or bed risers) produced a significant pressure drop, while simply stacking regular pillows did not reliably achieve the same effect. Pillows tend to elevate only your neck and head without changing the angle of your torso, which appears to be the key factor.
What to Avoid
Inverted Yoga Poses
Any position that puts your head below your heart causes a rapid spike in eye pressure. Headstands are the most dramatic example, roughly doubling eye pressure compared to sitting upright, but downward-facing dog, standing forward bends, plow pose, and legs-up-the-wall all produce significant increases within one minute of assuming the position. Pressure returns to normal after you come out of the pose, but repeated spikes are a concern if you already have elevated pressure or glaucoma. Other yoga practices like breathing exercises and meditation do not raise eye pressure and may actually help lower it.
Large Amounts of Fluid at Once
Drinking a large volume of water quickly, roughly a liter in five minutes, causes a measurable rise in eye pressure. The spike is temporary, but it’s significant enough that eye doctors sometimes use a rapid water-drinking test to assess how well the eye handles fluid changes. In practice, this means sipping water throughout the day is better than gulping large amounts at once, especially if your pressure is already borderline.
High Caffeine Intake
A single serving of coffee containing about 180 mg of caffeine (a standard 8-ounce cup of brewed coffee) raises eye pressure enough to be statistically measurable at 60 and 90 minutes after drinking it. Decaffeinated coffee did not produce the same effect. If you have ocular hypertension or glaucoma, moderating your caffeine intake or switching to smaller servings spread throughout the day may help keep pressure more stable.
