Amblyopia is defined as lowered visual acuity without obvious cause. It is a condition where the brain switches off one eye because there is conflicting or unequal input from the two eyes. Recently Ambliopia is also thought of as a sensory adaptation to Strabismus a condition where one eye is looking in a different direction. Amblyopia is a label that is often applied to a wide range of visual conditions where there is a diffrence between the eyes. Technically if both eyes have visual imput then the condition is anisometropia - a difference in visual acuity between the eyes. This is the case for many people.

Amblyopia may develop due to a number of reasons such as: Deviating eye Amblyopia is likely to develop in children under the age of 3 if one eye is deviating (turning in or out) as in strabismus. If untreated marked decrease in visual acuity may develop within just a few weeks.

Defocused eye

When one eye is severely near-sighted and the images appear blurred at all distances amblyopia is likely to develop. In adults having one eye that is severely near-sighted though wearing corrective lenses may develop amblyopia if vision training is not commenced. There simply is a slow deterioration as you get progressively stronger and stronger lenses.

Deprived eye

Amblyopia can develop as a result of covering one eyes for the whole day for as little as a week during the early stages of an infants vision development. The medical treatment of choice is patching the good eye, which over the years have been supplemented with active stimulation of the eye using electrical and chemical stimulants. Strategies used are total occlusion, excluding all light. For example using adhesive patches worn on the skin. Opaque black contact lenses, frosted glass and other filters may be used. Total occlusion is considered more effective than part time covering of the good eye.

Amblyopia is treated in childhood and is rarely started after age eight. The rule of thumb is to occlude the good eye for as many weeks as the child is old. If Strabismus is involved there is often surgical replacement of the eye muscles in an attempt to straighten the eye so both eyes are moving together for better cosmetic appearance. In a study, conducted by Watson et al. in 1985, comparing the effects of full time and part time occlusion reported that 23% of the patients showed no improvement despite very adequate and vigorous treatment. I have talked to many people who have gone though this treatment in childhood.

They all told me that they hated wearing the patch and that it didn't’t make much difference anyway. This is not to say that eye-patches do not work. They do, but the success rate is depressingly low. If you are a parent you can imagine how impossible it is to keep a eye-patch on a 4 year old child. In some cases the child’s arms have been put in splints to prevent them from ripping the patch off. Today many people would consider such measures child abuse.

The problem with the above approach is that it is passive and does not involve the mind. You are in essence trying the force the eyes to function normally. Amblyopia should be treated as soon as it is detected. However, in many cases people do not realize that they are using only one eye to see. It is a very gradual shift that is barely noticeable. Unfortunately there is a large number of adults with untreated amblyopia.

How effective is Vision Training?

Vision training is effective and can in many cases correct the amblyopia so both eyes are functioning normally. In most cases it is a lot of work, but is worth while because you are able to restore natural clear vision. The vision training is something you do for just a few minutes, but you do an exercise perhaps every half hour or so. It is not something that will take a long time. However, it is important that you exercise very frequently in order to slowly build up strength. Vision training is about getting flexibility and relaxation. Exercising for too long at one time may actually cause stress and tension.— slowly and often is what works best.

Depending on how severe the Amblyopia is, Vision Training may take months and even years before your vision is fully restored. The first milestone on your journey will be the day you can read using both eyes. Then be able to work without glasses when you can see at arms length and so forth.

There are two types of "Lazy Eye". One where one eye is more nearsighted, and one where one eye is far sigthed. Both are trainable.

What people say ...

"After many months of eager anticipation, Rebecca and I attended Leo's Magic Eyes workshop. Leo was able to quickly assess which exercises would be most important for each child in attendance, and we set to work! The results of these simple exercises were almost immediate.

Rebecca was so keen she was trying them in the car on the way home! After only the first session, for the first time in over seven years, Rebecca could take her glasses off and her eye would not turn! This was a very emotional time for all of us, and we cannot thank Leo enough for his help.

We have now been working on the exercises for a few weeks, and not only is Rebecca's turn rarely evident, her near points and far points have improved for each eye, and she has gone from wearing +4.5 lenses to +3 lenses. We still have a ways to go, but we are very determined!

Leo's knowledge is invaluable, and we only wish we had come across the techniques years ago. Our great dream for others is that Leo's strategies become the first point of call for children experiencing difficulties with their eyes. All we can say is THANK YOU, THANK YOU, THANK YOU!

P.S. - Rebecca is keenly passing on information about the next workshops to others with glasses, even her teacher at school! "

親愛的 Leo,親愛的司徒女士:


7月14日第一次到工作坊時,子敬有 300 度的近視,眼睛疲勞沒有神采,我們用 Leo 教授的繩索練習法和會聚力練習法回家積極練習,到7月15日的傍晚,子敬的近視已經降到 100 度以下了!簡直不可思議!7月16日第二次到工作坊時,看著 Leo 用視力表來訓練餘下的 100 度近視和用那有趣的小丑圖來治療省光,我已經由當初的半信半疑變到信心滿滿加上感激不已!






Mother, Hong Kong

Quite an an eye-opener. Amazing results within such a short span of time.

Useful to motivate Janelle and convince her that it can be done.
Janelle liked the alphabet exercise best of all. I liked the information provided and the eye chart exercises.
I would recommend the workshop. Useful knowledge for the whole family. ”
