It is well known that exercise helps both mind and body. Emory Eye Center research suggests it can also protect vision by delaying the death of light-sensing photoreceptor cells in the retina, which occurs in many forms of blindness in the elderly.
Researchers Machelle Pardue and Jeffrey Boatright exposed mice to bright light to harm their photoreceptor cells. They found that mice that ran daily on a treadmill suffered less cell loss and retained retinal and visual function compared with sedentary mice. The research has garnered significant attention, including The New York Times.
“This is the first report of simple exercise having a direct effect on retinal health and vision”
So while you work out in your personal exercise program, know that it might help your vision over time. Keep moving!
