Dr. Bates book with original practices included. This is an old-time Bates Method treatment. It can heal some types of blindness, advanced eye problems, cataract, glaucoma... It must be preserved but done correct. Complete old-original and modern directions, warnings must be taught for safety of the Sunglass (Burning Glass) because it is a magnifying glass and sunlight passing through a magnifying glass can burn, blind the eye. The sunglass is not needed except sometimes in advanced cases of vision impairment, blindness and should be done only by an expert Ophthalmologist experienced in the Bates Method and only after other Bates' methods are tried first.
The Sunglass is a magnifier, a glass and similar to a strong reading eyeglass prescription; sunlight passing through it becomes very unbalanced, no longer full spectrum, it converts to partial spectrum light and abnormally focused light which is not healthy, it's not the beneficial full spectrum sunlight we get when it's not passing through glass, plastic, windows, eyeglasses... People that use the Sunglass every day or weekly... are placing unbalanced, partial spectrum light on the eyes. This continual exposure to unbalanced sunlight waves, frequencies, altered energy is unhealthy. Even monthly or less often can be harmful; it is only needed for treating blindness.., some types of eye infections. and must be a temporary practice!
Using the sun-glass inside under artificial light bulbs (which produce unbalanced light), makes the light through the sunglass more unbalanced, unnatural, removes more of the light spectrum, impairs the eyes, retina, lens... health, function and clarity of vision. The light is not 'perfect' full spectrum as healthy natural pure sunlight not passing through a glass, even if you use the best full spectrum lamp. A safe type of full spectrum lamp (no fluorescent, no types that are too hot) is healthy for indoor light and can be used for sunning the eyes when stuck working inside and in low sunlight areas of the planet, but; passing this light through the sunglass makes it partial, unbalanced, unhealthy. This lamp can be used with the sun-glass for some benefit to the blind if pure sunlight is unavailable. Used correct, temporarily by an Ophthalmologist, the sun-glass treatment with pure sunlight can save the eyesight, the eyes health, but; it's a temporary treatment and is combined with permanent use of the Bates Method and natural full spectrum sunlight NOT passing through the sunglass. The Sun-Glass and Open-Eyed Sunning are not needed for most cases. Open-eyed sunning (and the Sunglass Treatment) are also controversial due to the depletion of the planets ozone layer from pollution so detailed instructions, precautions must be given. Some areas of the planet have better ozone protection. Colored spots in the visual field lasting for days, months is a side effect when these treatments are done wrong. Some open-eyed sunning can be done safely and with great benefit to the health of the eyes, body, mind and vision. Sunlight is a natural antidepressant, a healer. Vision can become clear, eyes healthy with use of the Bates Method, avoiding eyeglasses and obtaining natural exposure to normal sunlight by just walking outside daily, looking at the bright sky, clouds, trees, moving the eyes, head/face across the sun with blinking for short periods and using Closed-Eyes Sunning. Do not wear any type of eyeglasses, sunglasses, tinted, colored, UV blocking lenses, contact lenses... while sunning, sun-gazing, applying sunlight on sclera, using the sun-glass or any sunlight treatments. These eyeglasses, lenses can act as a magnifying glass causing sunlight through the eyeglass lens to burn the eyes even when the eyes are closed. The eyeglasses, lenses impair the natural structure of the suns light rays causing unbalanced, partial spectrum, unhealthy light to enter the eyes, visual system resulting in eye, vision, health impairment. NO binoculars, telescopes when facing the sun! (The sun-glass light never shines on, in the eyes pupil. It shines only on the sclera, white area of the eye.)
I prefer direct, pure full spectrum, balanced sunlight on the sclera `white of the eye' (pulling the eyelids up, down while looking in the opposite direction with the eyes pupil away from the sun. See directions, pictures on previous pages) without the light passing through the sunglass or any type of glass, plastic, eyeglasses, sunglasses... I also use closed eyes sunning and a bit of occasional open-eyed sunning done correct; look directly at the sun, always with eye, head movement, keep the eyes shifting, blink often, avoid staring. Move the head with the eyes, at the same time, in the same direction. Limit eye exposure time and protect the skin from sunburn. Good nutrition, diet, no drugs, chemicals... Healthy eyes work best with healthy full spectrum sunlight.
