ABSTRACT:
An apparatus for causing constriction of the pupils of a person's eyes which have corneal deformities so that light is not refracted through the corneal deformities, thus impairing the vision of the person. The apparatus includes a support frame with a first frame member having a nose rest associated therewith, a second frame member having an ear rest associated therewith, a first hinge which connects the second frame member to the first frame member, a third frame member having an ear rest associated therewith, and a second hinge which connects the third frame member to the first frame member. A first light source supported by the support frame generates light of an intensity sufficient to cause constriction of the pupil of one eye of the person, and a second light source supported by the support frame generates light of an intensity sufficient to cause constriction of the pupil of the other eye of the person.
