Regular physical activity promotes eye health

Scientists are still working to understand how exercise protects the human eye. Their discoveries could unlock treatments for a number of eye conditions.

But for now, it's clear that exercise can prevent some eye conditions. And if you already have a disease, exercise can help you better manage it. One study found that people who engaged in moderate physical exercise were 25% less likely than inactive people to develop glaucoma. In people who already have glaucoma, regular exercise can lower intraocular pressure and improve blood flow to the retina and optic nerve. Physical activity can also help people with diabetes keep their disease under control. That reduces the risk of complications, including diabetic retinopathy, the leading cause of vision loss among working-age adults.

How much exercise should you practice?

The new study reinforces the recommendation that regular, moderate exercise is good for your health. The CDC, WHO and the American Heart Association recommend 150 minutes of moderate aerobic exercise per week. That equates to about 30 minutes a day, 5 days a week. This can include walking, bicycling, swimming, dancing, and even active gardening. Regular physical activity can help keep you and your eyes healthy.
