Can exercise really improve your eyesight? If you have opted to improve your vision through laser eye surgery, and are now seeing the fantastic results of 20/20 vision or better, you will want to maintain those results for as long as possible.
New studies in the United States suggest that keeping up with aerobic exercise will help to keep your eyesight perfect for longer and can even delay the progression of diseases that can eventually lead to blindness such as Age Related Macular Degeneration (AMD). It is thought that aerobic exercise works by stimulating a protein in the brain called Brain Derived Neurotrphic Factor (BDNF). This protein is special as it helps brain cells to grow and also to stay healthy, and scientists believe that this could also be the case for the cells in the eye that process light. Tests have so far have just been carried out on mice, but the results are looking very positive. The scientists tested two groups of mice, one group that had a fixed treadmill, and the second group whose wheel was able to turn. They found that the mice that were running regularly on their treadmills had twice as much retinal function than the inactive mice, and 20% higher BDNF protein levels. Dr Pardue who was working on the project says:
“This is the first report of simple exercise having a direct effect on retinal health and vision. This research may one day lead to tailored exercise regimens or combination therapies in treatments of blinding diseases.”
So step to it, keep those limbs moving and heart pumping, it can reduce your risk of major illnesses, such as heart disease, stroke, diabetes and cancer by up to 50% and lower your risk of early death by up to 30% and even help you eyes to carry on seeing clearly!
