The Claim
Regular aerobic exercise is associated with lower rates of glaucoma through improved optic nerve perfusion and modest reductions in intraocular pressure.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People who regularly do aerobic exercise have lower rates of glaucoma, which is linked to better blood flow to the optic nerve and slightly lower eye pressure.
See the scientific wording
Regular aerobic exercise is associated with lower rates of glaucoma through improved optic nerve perfusion and modest reductions in intraocular pressure.
When a person exercises, their heart beats faster and they sweat, which reduces the amount of fluid the eye makes and opens up a drainage channel in the eye. This lets more fluid escape, lowering the pressure inside the eye and improving blood flow to the optic nerve.
What the research says
3 studiesPeople who jog or exercise regularly have lower eye pressure and better blood flow to the back of the eye, which helps protect against glaucoma. This study showed that just 30 minutes of morning jogging most days lowered eye pressure by a few points.
People who exercise for 30 minutes, like walking or running, temporarily lower the pressure inside their eyes and open up the eye’s drainage channel — which may help prevent glaucoma over time.
