Glasses have been around for centuries to help improve and provide clearer vision. More modern methods of vision correction such as contact lenses and eye surgery are more advanced, but actually treat the symptoms rather than the cause, just as glasses do. Even pinhole glasses have been used to focus light rays on the retina.
It is believed that glasses promote further deterioration of the eyes, and prevent natural healing. Glasses put additional strain on the eyes. Natural vision coaches recommend their clients stop wearing, or at least get a reduced prescription, when using natural vision correction methods. Natural vision coaches teach that if the eyes are relaxed and reconditioned, vision will improve. Eye exercises are used to train coordination and flexibility for muscles in and around the eye. They strengthen the muscles and nerves in the brain and vision system to help correct vision.
Relaxed central vision is a key to natural eyesight improvement according to the natural vision coaches, or Bates Method practitioners. However there is some debate whether natural vision correction is valid. For example it is not recognized by the American Optometric Association.
People that practice natural vision correction usually are not licensed professionals however; some licensed professionals may practice natural correction on the side.
The benefits of natural vision correction are that it is a non-invasive, natural, and holistic method that can be used alongside other vision aids such as glasses and contact lenses. There is no risk involved whilst trying natural vision correction methods. The downside is that it can take time to notice any benefits.
