Exercise eye focus
Hang the two saccade panels about 30-40 cm apart next to each other at eye level on the wall and stand in the middle in front of them (wall distance about 1 m). Now jump from letter to letter with your eyes (1st line left, 1st line right, 2nd line left, 2nd line right etc.). Don't jump any further until you see the letter clearly. Saying the letters out loud supports the exercise.
This exercise can also be performed with the Vision Sticks.
