Pinhole glasses and Black Eye Contacts are tools that serve to re-educate and improve sight. These consist of perforated lenses and designed according to the method of Dr. Bates who proposes to cure various visual disturbances using techniques and exercises.
The Bates method proposes to cure visual disturbances (such as astigmatism, myopia, hypermetropia and presbyopia) through techniques and exercises of the eyeball. Dr actually considered unnecessary, and sometimes harmful, the use of prescription glasses or specific surgical procedures to solve problems related to vision. This is because, once these solutions were put in place, the interested parties could even have noticed some deterioration.
A little ‘as it happens for the so-called lazy eye, then, Bates claimed that the ocular system should be stimulated in general, in order to obtain a better view. According to Bates’s theories visual defects are generated by the effort to see better.
