Some eye exercises that can stimulate tear ducts can help treat dry eyes effectively. One of these eye exercises is blinking. Close your eyes tightly for several seconds and then open them to start blinking for a few times. Repeat this exercise untill the tears flow. Then the tears will keep your dry eyes moist. Or you can move your eyeballs to stimulate tear ducts and help treat dry eyes. Just move your eyeballs to the left and right as long as possible, and then up and down, which may help the tears start to flow and then treat your dry eyes.
