Abstract: Method and apparatus for restricting field of vision so as to provide a dyslexic reader physical means for narrowing field-of-sight concentration in order to prevent eye wander and aid in normal compensatory sight narrowing by the reader. The method comprises an obfuscation of the peripheral field of vision while concurrently focusing or providing clear viewing means in the centralized, enhanced narrow reading field. The aforesaid method is readily accomplished by use of either the pin-hole camera, consisting of a minute aperture in an eye-enveloping, obfuscating field or, more practically, a set of spectacles consisting essentially of opacified or defocusing lenses having with them a centralized clear field-of-vision lens, window or aperture which effectively accomplishes in both eyes of the dyslexic reader what the pin-hole aperture does for a single eye.
