Excerpt:

Introduction Running and jogging improve cardiovascular health and overall wellness, but people with glaucoma often wonder if pounding the pavement could harm their eyes. Glaucoma is a group of diseases marked by damage to the optic nerve, often linked to higher-than-normal intraocular pressure (IOP). In a healthy range, blood pressure drives fluids through the eye (the ocular perfusion pressure, or OPP). For glaucoma patients, maintaining stable blood pressure and eye pressure is crucial. This article explains what happens to IOP and OPP during moderate-to-vigorous running, highlights exercise benefits for vascular and brain health, and warns about possible downsides (like dehydration or impact shocks). You will also get practical tips on safe running intensity, staying hydrated, and special precautions if you have narrow-angle glaucoma, advanced vision loss, or balance problems. Finally, we’ll give clear guidance on how far and how fast to run, and what warning signs to watch for.

How Running Affects Eye Pressure Aerobic exercise (like jogging, running, or brisk walking) has immediate effects on eye pressure. Numerous studies show that IOP falls right after a workout. For example, a controlled trial found that after short-term moderate exercise, average IOP significantly decreased while OPP increased (). Similarly, in healthy and glaucoma eyes alike, 30 minutes of steady treadmill running produced a significant drop in IOP (). In other words, your eye pressure tends to go down once you start moving.
