Focus Shifting

Relax your body and breathe comfortably. Hold one arm straight out in front of you in a loose fist, with the thumb pointing up. Focus on your thumb. While keeping your eyes trained on it, slowly move the thumb toward your nose until you can no longer focus clearly on it. Pause for a breath or two, and then lengthen the arm back to its original outstretched position, while maintaining focus on the thumb. Repeat up to 10 times.
