Role of Eye Exercises in Myopia?

There is much curiosity about eye exercises as a panacea for keeping the eyes healthy. There certainly are benefits of physical exercises, e.g. walking on green grass in the morning, looking at the rising sun, deep breathing, pranayam and other forms of yogic procedures to maintain healthy eyes. These are recommended by all for they do supply the much needed tone and strength to the entire system of which the eyes are a vital organ. But to claim that glasses can be completely done away with by any kind of exercises and naturopathy is stretching things into unscientific fields. Shortsightedness is an anatomical variation where the eyeball is longer them normal. There is no exercise which can shorten its length. Every 1 mm increase or decrease in length will increase or decrease the power by 3.
