Eye Exercises  ⁄  10. Divergent Fusional Reserve 1°. 1-pointed Route

This is the first exercise from the intermediate-1 course. This course helps us to develop the divergent fusional reserves. In other words, it’s the medial eye muscles’ stretching exercise. Also the lateral eye muscles become stronger. As result, the distant vision becomes easy and comfortable for myopic people.

At the beginning of the exercise the distance between two red dots is the same as pupillary distance. So the visual axes are parallel and the angle between them is zero degree. When the colored dots go up, the distance between them increases. The same happens to the angle between visual axes. On the top the angle between visual axes reaches to 1 degree. When the colored dots go down, the distance slowly decreases. The angle between visual axes goes down to zero degree i.e. parallel viewing.


Let me know if you have any questions.

    Doc, silly question but I want to make sure I understand.

    Is the goal of this exercise to learn to move your eyes beyond parallel? So you are facing out? Like simulating “wall-eye” ?

    David, the goal is to improve the central vision at far distance and supress the peripheral vision. Also the exercise is some kind of stretching for eye muscles.

    Thanks Doc.

    I’m sorry but I asked an unclear question. I meant to just clarify that when doing the exercise, one is attempting to fuse two targets which are on the outside of each eye?

    I have worked on divergence exercises for a long time using exercises here and with “lifesaver charts” so I am comfortable, but I’ve never worked with targets beyond parallel to pupillary distance because I assumed it was impossible. Going just 1mm beyond my pupillary distance at arms length is very challenging and I want to make sure I am doing it right!

    David, usually the divergent fusional reserve is about 3 – 5 degrees. It means that at arms length – 58 centimeters – the distance between the visual targets is equal to the pupillary distance plus 30 – 50 millimeters. I have worked with some patients who had 8 degrees of divergent fusional reserve (PD + 80 mm).

    That makes sense. Thank you!
