Eye Exercises  ⁄  Myopia and Development of Fusion Ability

In the last few lessons, I told you about controlling the visual axes. I hope you got the concept of vergence movements. But knowledge and understanding are ambiguous. Knowledge becomes understanding only through practice. Visual imagination (visualization) of ocular rays helps you understand the intersection point. For better vision, the equal participation of both eyes, called ambidexterity, is necessary. I see a lot of people with myopia that have no ambidexterity, and their leader (driving) eye has better visual acuity. Weak (driven) eyes are about 0.5 – 1.0 diopter more myopic than the driving eye. However, when a patient develops strong binocular skills with an improvement in ambidexterity, the formerly weak (ex-driven) eye develops better visual acuity, as does the leader eye.

Lesson 16 – Myopia and Development of Fusion Ability

Thus, binocular vision is a difficult subject to master just by reading articles – practical experience is essential. For the best binocular vision, the equal participation of both eyes is required as well as precision control of the visual axes. Now check your fusion ability. In the picture below, you see four identical images in each row. Relax the medial rectus muscles and move the point of intersection of the axes behind the screen. Imagine you are looking through the picture, and the visual axes will diverge. The image will appear double. After fusing you can see five objects in each row. Make sure that the middle part of the image becomes brighter, sharper and deeper. Additionally you will see a 3-dimensional (stereoscopic) image.


If it does not work the first time, take the following actions – first look at the center of the picture. Then look through the picture behind the screen surface, while relaxing the eye muscles at the bridge of your nose. The movement is like the fifth movement of warm-up, when you move your eyes from the bridge of your nose to the primary position. When done properly, the objects will appear double. If one row is above another, incline your head a little to the right or to the left. After fusion you will see five objects in each row. When fusion occurs, the edges on the right and on the left will be translucent, and three baseball players in the middle part of picture will be bright and sharp. With the correct actions, the image you see will be similar to the picture below:


During fusion, gaze attentively at the picture, and you will see a transparent baseball helmet and two baseball bats in the middle of the picture, as in the diagram below. Pay attention – the images of the helmet and the bats are stereoscopic.


The next picture is even more interesting. Do the same thing you did in the previous exercise. Look through the picture and intersect your visual axes behind the screen. Objects will appear double. After fusion, you will see a three-dimensional image of flying saucers – two small ones above and a big one below.


If the rows are at different levels, incline your head to the necessary side. Controlling eye muscles fuse corresponding images onto each other. If you do it right, you will see the picture as below:


Gaze at the picture attentively. In the middle of the picture you will see three stereoscopic images of flying saucers, as in the diagram below:


This exercise may be difficult for you at the beginning. Never give up! An analogy can be made with learning to drive. In the early days, novice drivers pay more attention to the techniques of driving and less attention to where they are going. After a while, the procedure of driving becomes secondary and deciding where to go is the primary concern. The same is true for better eyesight improvement.

It is never too late to take care of your eyes.

Merry Christmas and a Happy New Year!

    Next day I couldn’t do the further intersection anymore. But I observed (and knew from before) that the left eye was muscularly weaker and slower (its acuity and colour perception have improved and fluctuate a bit under and over the level of the right eye). The lateral muscle of the left didn’t seem to contract enough and the medial didn’t seem to stretch enough to attain the fusion required by the exercise. So I rested the left eye by wearing an eyepatch for several hours. When I tried again, it immediately reacted as it should and the fusion took place, and the rest of the exercise evolved as described in the theory part. I thought it would be best to strengthen the weak link in the process, so I just kept doing the exercise (by keeping the fusion in place) for at least an hour. During this time I had several moments of deep relaxation, and a kind of evaporation of tension took place around the eyes and in the muscles. Also, a few times, the left eye just literally fell away, feeling limp for a second and then flipping back into position. When I would lose the fusion (and the intersection point behind the screen) and couldn’t do it anymore, I would get closer to the screen and recover it.
    A sensation of freshness around the eyes was the a result and during the night important but forgotten information about the weaker condition of the left eye showed up.
    Yesterday the story was similar, but there was an increasing pleasant pain in both laterals, as if they were pulled at from outside with increasing force. Results: a freshness around the eyes and improved control of the laterels. The next exercise with the cat succeeded as well, so I ventured to try the exercise with the baseballers. This was a wonderful experience!! I had to start close to the screen though, and, as with the previous two, I then increased distance. The stereoscopic helmet would become less clear, but be clear enough to keep me fascinated for at least an hour.
    I think the entire image has a touch of a genius doc, both as the form of the exercise and where results are concerned, because afterwards I noticed a process of rebalancing was taking place between the medial and the lateral muscle functions. And when I woke up this morning my sight was better than usual. Later on in the day, I could change focus better and see things with less effort as a result. I seem to get more control in the lateral muscles and the medials seem to become more flexible. Like this I might be able to win the game against the strain patterns I have developed.
    Last but not least, may God bless you in 2010!

    Mat, really the visual training is similar to a tug of war, yesterday you became the winner and make a fresh start today. It’s OK, there is no rush. Approximately during 3 months new visual skills become habitual. I’m glad that you did the baseball, and what about the flying saucers?

    The flying saucers appeared neatly but the cat-fusion exercise doesnt quiet work out, all though there is progress.
    Otherwise I have had the oblique muscles relaxing lately with interesting results. It is also mentally beneficial.
    THe variableness in acuity has increased lately, as if things are fighting, so your tug of war makes sense.
    Regards, Mat

    Hello Doc,

    Please specify the distance from the visual target for performing this activity.


  5. Doc:

    30.11.2012 at 20:42 #

    Abida, the distance is about 35 – 45 centimeters.

    Hi Doc,

    I am so glad I am able to do the exercises given above properly.I am doing these exercises with under corrected glasses.My question is are the glasses needed for these exercises?

    Abida, that’s not an exercise. That is a test to check your ability for fusion. You can use your minus glasses for near vision (2-3 diopters less than your current prescription).

    Hi doc,
    I don’t know if something has changed in your server but the pictures with the helmet and the last one don’t appear stereoscopic at all!

    Oups! Sorry, my mistake. The transparent helmet will appear in the first picture as well.
