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
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.
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.

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.
"My son has been using Leo’s exercises for the past couple of years and has, by doing so, gone from a point where we were practically accused of child abuse by his school nurse for ignoring his deteriorating eyesight and not getting him glasses, to the point now where he is learning to drive glasses free, which thoroughly vindicates our belief in Leo’s methods.
This is powerful stuff which should be taught in schools – rather than carting kids off to the opticians to condemn them to a life behind glasses. I urge everyone who wants to solve their eyesight problems to try Leo’s methods. Attending his workshop is by far the best way of doing this but, If this isn’t possible, Leo has written 3 books covering his methods"
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！
Thank you very much for solving my problem I can read and i like read- ing too.
I read COOL it is a book by Michael Morpurgo it is about a kid who gets knocked over by a car and is in a coma and his dog get him back .
But just so you know i did not do the X’s 50 times, but it still worked it is like magic thank you.
I’ve told my friend Celeste to do it because she has dyslexia.
"My daughter Rebecca was diagnosed with strabismus, astigmatism, and long-sightedness at the age of 18 months. She was wearing glasses all day, every day from the age of 21 months. We had many stressful years of patching, drops, and exhaustingly long visits to the opthamologist, only to have her scripts get stronger over time. Rebecca could not be without her glasses, and as soon as she took them off, her left eye would turn harshly in.
As she grew older, Rebecca began to become more and more self conscious and felt that she stood out because of her glasses. She is passionate about her dancing, and has been performing since the age of 3. However, at the time of each concert she would express concern that she was the only one wearing glasses, and that you could not see her beautiful make-up properly! Yet she could not take them off as her eye would very clearly turn.
We discussed her concerns often, and she even tried contact lenses at the age of 8, however she resigned herself to the fact that she would always have her glasses. Her optometrist kept her hopes up by explaining that there was much research being done, and that operations were always improving. Her father and I were not comfortable with the thought of her eyes being operated on, and we explained that when she was older, the decision would be hers to make.
One night Rebecca saw an ad for a current affairs show which was airing a segment about getting rid of your glasses. She excitedly told me about it, and we made a point of watching it. Following the show, I made contact and booked Rebecca in for a children's workshop with Leo.
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!
