Abstract:
A contact lens for training and rehabilitation of a targeted hemisphere of the brain of a person by placing the contact lens on an eye of the person so that visual sensory input through the pupil of the eye of the person is substantially reduced to a non-targeted hemisphere of the brain of the person and substantially forced to the targeted hemisphere, comprising:a first region of the contact lens comprising a substantially transparent material over a first portion of the pupil so that a significant degree of visual sensory input is allowed to reach the targeted hemisphere; a second region of the contact lens comprising a substantially opaque material over a second portion of the pupil so that visual sensory input is substantially reduced to the non-targeted hemisphere; a third region of the contact lens comprising a substantially transparent material over at least a portion of the lateral area of the pupil corresponding to the non-targeted hemisphere whereby visual sensory input to the peripheral visual field of the person allows the maintenance of orientation and balance; and means for preventing rotation of the contact lens on the eye of the person.
