Let your eyes move, so you can exercise.

The practice is: separate your feet from your shoulders, stand tall and tilt your head slightly. Open your eyes wide and try to move your eyes (don't move your head). First turn right to left 10 times, then turn left to right 10 times. After a rest 10 minute, repeat the above exercise (sports food) three times. This method is best done in the garden in the morning, which can refresh your mind and improve your eyesight. In addition, regular eye movements and looking up at distant mountains, roofs, spires, rivers and other scenery can also adjust eye muscles and lenses, reduce eye fatigue and improve vision.
