Optometrists have long been concerned with the fact that amount of eyestrain caused by reading can cause increased nearsightedness (myopia). This is now more true than ever with the increased use of computers and handheld video games. There is increasing research that shows that if the the near work is broken up by other activity, such as out door exercise, it can minimize the progression of myopia.
A new study supports this idea:
An association between physical activity and myopia was observed, suggesting a protective effect of physical activity on the development and progression of myopia in university students. The results confirm that intensive studying is a risk factor of myopia and that myopic progression or development is more likely in medical students in their early 20s than in their late 20s.
The summary of the the study is here. But instead of reading it, maybe you should go out and get some exercise!
