Natural Vision Therapy is a proven, non-intrusive, and holistic approach to improving short-sightedness (myopia), astigmatism, long-sightedness (hyperopia), and old-age blur (presbyopia) without the use of glasses or any medical aids. The Therapy re-educates the eyes and mind about the principles and habits of seeing clearly and naturally. Its foundation is based on the Bates Method which is a time-tested solution for many functional vision problems. Dr Bates, an ophthalmologist, stopped prescribing glasses to his clients after noticing that their eye problems got progressively worse after wearing the "eye crutches". He discovered that the glasses, or eye crutches, actually prevents the eyes from healing itself naturally. His more than 30 years of research to find an alternative to eye glasses was published in "Perfect Sight Without Glasses" in 1912, . This book has been reprinted as "Better Eyesight Without Glasses", and is still a best seller in any leading bookstores today. Dr Bates had helped thousands of adults and children to perfect sight without the use of glasses. The Bates Method is taught in many countries around the world by Bates teachers who are in one way or another had been taught by Dr Bates, his wife, Emily Bates or their disciples over a 80-year timeframe. Natural Vision has incorporated some of the key Bates Method techniques into an easy to implement, natural eyesight improvement program, by combining a pair of Vision Therapy Eyewear, or Pinhole Glasses, User Manual, Far and Near Training Eyecharts. The pinhole glasses, together with some eye exercises, will bring about better eyesight without glasses, lasik, and medication. This vision improvement method is suitable for children and adults with nearsighted (shortsighted or myopia), farsighted (longsighted or presbyopia), astigmatism, and lazy eye (or strabismus) vision problems.
