Mind and Vision is a handbook that explains in simple terms the basic workings of the eye and how normal eyesight can be defined, evaluated, and maintained; the causes and cures of errors of refraction; such conditions as squint, floating specks, double vision, cataract, and glaucoma; and a wide variety of treatments and relaxation methods designed to balance the workings of the eye and the mind in a perfect stasis of restful movement.
