1. Take a stable posture and set your hand with your index finger up at the level of your head in front of you, about 30 cm from your eyes.
2. Look from your fingertip to the horizon line or to any distant point, lingering in each position for 2-3 seconds. The finger should be approximately in the same direction with the selected point, so that when you look, the eyeballs hardly move. Both the finger and the horizon must be watched carefully, achieving clear concentration.
3. Perform from 1 to 3 minutes
4. Relax your eyes after the exercise.
Exercise enhances the eyes’ ability to focus accurately at various distances. Vision improving happens due to increased accommodation (the ability of the lens to change its curvature).
