The author, who is neither an ophthalmologist nor an optometrist, operates a "reading center" under his own name on Long Island, NY. He advocates that victims of dyslexia be tested by: (1) a "visuascope"—apparently a stereoscope. This determines "whether both eyes are sluggish, or whether or not the individual can see well enough to do school tasks," and (2) a "metronoscope" (Risley prisms). "The base-in reading indicates the divergence reaction in its relationship to the function of the focus mechanism while the base-out reading indicates the convergence reaction in its relationship to the functioning of the focus mechanism" (sic); and (3) a "Reading Graph" of ocular movement. If the "convergence-divergence response" is considered insufficient, training by prisms is undertaken.
