Hier gibt es ein englisch-sprachiges FAQ:

Will I have to keep doing exercises forever?
Once your vision has returned to normal more permanently, it becomes easier to keep it so. Seeing blurry involves a lot of strain that is taxing on your energy. Seeing clearly is a habit of correct use of your eyes that you (re)learn and is inherently easier and more preferable as you get used to it. The exercises only help you on your way. If you do find your vision slipping at some point, you know what to do to re-establish the clear vision, whether it's temporary use of some exercises or just a moment of examining how you're using your eyes and re-asserting the correct way that you have already learned. People with normal vision do not do exercises to maintain it, and neither do you need to. Your eyes are used all day long, and the way they are used all day has a much bigger impact than anything else. Similar to how your heart is challenged and becomes healthier by intense physical activity, your eyes are challenged by difficult visual situations and become better able to adapt to them.
How do you convert between 20/x and diopters?
How do you convert between acuity (noted as 20/50, 20/100, etc.) and a glasses prescription in diopters (-2, -5, etc.) ?
You can probably find someone to suggest a conversion table or another way to convert it, but there is no such conversion. It's two different things that only correlate very roughly, and even then only sometimes.
Acuity is a subjective measurement of what sized letters you can read on an eye chart at 20ft. Other than your quality of vision, this will vary by lighting levels, the chart used, and how good of a guesser you are. A diopter is the unit of measurement used for prescribing glasses to "correct" your vision for either distance (20ft or farther) or reading distance (18in). It is determined by calculations involving the light rays not being focused properly by your eyes and how much of an angle is needed to correct it. There is also usually at least a small amount of astigmatism correction noted in the prescription. Various conditions or diseases will affect how well you actually see. Misusing your eyes by a greater or lesser amount than you habitually do will affect it as well.
Diopters should be of little or no concern to people improving their vision. You can't easily measure it yourself, and it doesn't correlate well to how well you actually see, whereas an eye chart is a much better representation of the changes in your vision over time.
How can I address my child's vision problem?
If you have vision problems of your own, you can't help your kid until after you help yourself. Your kid will imitate the way you use your eyes. You're whom he probably picked up those kinds of subtle habits from in the first place. If you (or another parent or guardian) have poor vision, first practice the Bates method successfully yourself before trying to teach it to the kid. If your vision is already good, you probably have noticed times when your vision isn't perfect, and you can put the method to use on yourself in order to understand how it works. You can't teach something that you don't understand, and you don't understand it well enough to teach it until you've recovered your vision yourself.
Can I keep wearing my glasses?
The bottom line is, putting on your prescription glasses helps you accomplish tasks, and they're also bad for your eyes. If you're going to wear them, don't try to get someone here to make you feel better about it, because you're only fooling yourself. If you diligently practice the exercises, occasionally wearing your glasses might not prevent you from recovering your vision. Glasses interfere with the visual biofeedback in that the clear vision they help produce suggests that everything is okay and that there is no severe misuse of the eyes going on. It leads to a mess that people must find their way out of as they relearn, without glasses, what really affects their vision positively or negatively. Glasses really aren't the problem; misuse of the eyes is the problem. But glasses cover up the problem and mislead you. How often will you participate in the illusion?
Try pinhole glasses if you need to wear something sometimes. They still have the drawback of helping to produce a sort of clear vision despite continuing misuse of the eyes, but people often find for whatever reason that wearing pinhole glasses results in a feeling of instant relief for the eyes, as if much of the eyestrain just disappears, whereas prescription glasses do not help produce the same beneficial feeling.
What about other vision improvement programs?
There are constantly new websites popping up trying to sell you their package or promoting another theory about vision. We believe that the Bates method is the most direct way of resolving vision problems. Some websites do have products or info that actually are good presentations of the Bates method. But the Bates method is subtle and often misunderstood, so just because something says it's the Bates method doesn't mean it is. The Bates method really is NOT complicated, and you don't need to go seeking out the latest and greatest product for it. Just because you buy something and follow instructions doesn't mean you're really doing anything helpful for yourself.
What is a clear flash? Is it real or just an optical trick?
People improving their vision experience, as part of the process, flashes or longer moments of improved vision. This is often a sign that a person is - at least somewhat - using their eyes correctly for a moment and the visual system is free to self-correct and produce clear vision. This can last any amount of time - a second, several minutes, hours, or permanently clear vision. These periods of improved vision become more frequent, longer, or clearer as a person successfully applies the process in using the eyes correctly.
The misunderstanding about this revolves around the fact that there are certain misleading ways that vision can be "improved" temporarily. I have "improved" in quotes because such ways do not improve the process of vision as a way to correctly use the eyes without strain and promote good vision long term. These include:
* Squeezing the eyes shut tightly and opening them
* Narrowing the eyelids (squinting)
* Producing heavy tears
These are optical tricks having to do with the way light enters the eye and possibly the shape of the cornea or other unknown factors. They are not recommended. They can't be maintained as a way to support correct use of the eyes, and they may even be harmful long term as much as glasses are in the aspect of incorrect biofeedback.
With sudden clear vision that is "real", or in other words produced by the visual system as a response to the support received in the process of correct use of the eyes, people also commonly feel different in a variety of ways. Their eyes may feel lighter, other muscles in their body may relax such as in the face, neck or shoulders, they feel mentally calmer or quieter, and various other physical or emotional sensations.
How long will it take?
It takes as long as it takes you to learn how to identify how you're misusing your eyes and stop doing it as a matter of habit. If you're open-minded, humble, adapt to new ways of doing things, learn well on your own, and can listen to your body, you may find yourself seeing clearly more often immediately, in just days or weeks, and even notice changes in your vision in a matter of minutes or hours. This is true even if your condition is long-standing. If you lack all of these qualities, you may not ever make any progress at all. Others take months or years to recover their vision as they remain only partly committed and remain distracted by life. Be prepared to dedicate at least half an hour per day of practice, preferably with the feedback assistance of an eye chart at least some of the time, and the rest of the day you should apply what you learned during the practice time.
Will it work for me?
It depends. This is an educational process that requires you spend some time at nearly every day to make any progress. There are many cases of reversing common conditions such as myopia, hyperopia and astigmatism, as well as correcting conditions such as strabismus. There have been cases of improvement or complete recovery from diseases of the eye such as cataract, glaucoma and inflammations. There is disagreement on precisely how these various conditions are benefited, but the common factor among them all seems to be a misuse of the eyes leading to feelings of eyestrain and tension. When people relearn to use their eyes in the correct way, the entire visual system appears to work as a cohesive unit to self-correct and promote clear vision, whatever it takes.
