Abstract
Abstract The disclosure relates to lenses adapted to be used for reading and similar close-vision purposes by individuals having defective vision, namely, presbyopia or other refractive error. The lenses are sufficiently small that when they are mounted on the lower eyelids, out of contact with the corneas, the wearer may look over the tops of the lenses at distant objects. The lenses are combined with mounting means adapted to effect adhesive mounting of the lower lens portions onto the upper margins of the lower eyelids. The disclosure further relates to a method of mounting such lenses before the eyes of persons having defective vision.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
272 words
A lens device for compensating for defects of vision, which comprises: a lens shaped to compensate for defects in the vision of a human eye, said lens being sufficiently small that it will fit in the space between the adjacent marginal edges of the upper and lower eyelids of said eye with the upper edge spaced from the upper eyelid so that the wearer may view distant objects without looking through the lens, and means to mount said lens to only said lower eyelid and in a position between said eyelid edges and spaced forwardly from the cornea of said eye, said mounting means including adhesive means adherent to said lower eyelid, said lens being concavo-convex and having a generally semicircular upper edge lying generally in a single plane, said lens being adapted to effect magnification for viewing close objects, said mounting means including a horizontal flange extending inwardly from the lower edge of said lens for attachment in conforming relationship to the surface of the upper marginal edge of said lower eyelid, said lower edge being generally along a diameter of said semicircular upper edge, said flange extending generally toward said plane of said upper edge and toward the cornea and being generally crescent-shaped in outline, said adhesive means being provided on the lower surface of said flange, whereby the lens is entirely supported by adhesive attachment of said flange to the upper marginal edge of said lower eyelid with the upper edge portion spaced sufficiently far from the adjacent portion of the cornea to permit the upper eyelid to pass downwardly between the lens and the cornea during eye closure.

Dependent Claim

The invention as claimed in claim 1, in which said adhesive means is a pressure-sensitive adhesive.
Claim 4
Dependent Claim
31 words
