I quote from these two sources as to why a child should never be made to wear glasses or contact lenses:
“While it is true that eyeglasses bring some people improved vision and relief from pain and discomfort, they always do more or less harm, and at their best they never improve your vision to normal. After you begin to wear glasses, in most cases, the correction has to be steadily increased in order to maintain the degree of visual acuity secured by the aid of the first pair. Your vision wearing glasses progressively decreases with time. It really is tragic when children are condemned to a lifetime of having to wear glasses because of all age groups they are the ones that best respond to natural eye improvement strategies.”
~ Dr. Mercola’s Vision Program (based on Bates Method)
The photo below is an important page from the Relearning to See eyesight book.
It contains an excerpt from Dr. Thomas H. David, who writes:
“To put on glasses when one has developed a strain may give temporary relief, however, if incorrect habits of using the eyes are not overcome, the wearer returns to the eye specialist for an increase in the lens.”
