It is unfortunate that people with refractive errors will buy this book, which was written by an accountant, not any sort of health care practitioner. As an eye doctor, I see many types of ocular problems, and, yes, some of these can benefit from exercises. Roy's book misreads Bates's work, is ignorant of ocular anatomy and promises results that just cannot be delivered. Again, ther are some eye conditions that benefit from exercises, but many (most?) do not. See an accredited optometrist or ophthalmologist for help. Behavioral optometrists are especially aware of eye exercises regimens for improving vision. Most people are only to willing to part with their money for miracle cures, be they surgeries or exercises. Please take responsibility for your own health - find out the facts yourself. The author of the above book published and toured to support her book for one reason - cash. Don't let it be yours.
