Abstract

Abstract Apparatus for supporting and positioning a contact lens to facilitate applying the lens to the eye. The lens is supported on a receptacle by fluid surface tension. A beam of light passing through the supported lens enables the user to accurately preposition the lens with respect to the eye. The light provides a visual cue indicating lens contact with the eye, and the eye-lens surface tension causes the lens to remain on the eye.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 90 words
Apparatus for retaining and inserting a contact lens comprising: housing means; liquid receiving means supported by said housing means and having a wall portion permitting illumination to pass therethrough; contact lens receiving means disposed in liquid communication with said liquid receiving means and optically aligned with said wall portion, said lens receiving means shaped to conform to an exterior surface shape of a contact lens; and a source of illumination positioned within said housing means to selectively direct illumination toward said wall portion and thence toward said lens receiving means.
Claim 2
Dependent Claim 90 words
Apparatus for retaining and inserting a contact lens comprising: housing means; liquid receiving means supported by said housing means and having a wall portion permitting illumination to pass therethrough; contact lens receiving means disposed in liquid communication with said liquid receiving means and optically aligned with said wall portion, said lens receiving means shaped to conform to an exterior surface shape of a contact lens; and a source of illumination positioned within said housing means to selectively direct illumination toward said wall portion and thence toward said lens receiving means.
Claim 3
Dependent Claim 33 words
Apparatus as in claim 1, wherein the area of said lens receiving means which comes into proximate contact with a contact lens is less than the area of eye contact of such lens.
Claim 4
Dependent Claim 33 words
Apparatus as in claim 2, wherein said liquid communication is provided by an aperture within said area of said lens receiving means, said aperture being in liquid communication with said liquid receiving means.
Claim 5
Dependent Claim 53 words
Apparatus as in claim 3, wherein said liquid receiving means is selectively operative to dispense a quantity of a liquid received therein through said aperture and onto said area of said lens receiving means to permit a contact lens to be retained on said area by the surface tension of the dispensed liquid.
Claim 6
Dependent Claim 43 words
Apparatus as in claim 4, wherein said source of illumination comprises electric light means disposed within said housing means to direct illumination toward said wall portion of said liquid receiving means; and electric switch means in controlling circuit with said electric light means.
Claim 7
Dependent Claim 119 words
Apparatus as in claim 3, wherein: said housing means is generally in the shape of a partially hollow cylinder having a first end open to the interior of said cylinder and a second end; said liquid receiving means being removably received within said first end and having said wall portion disposed within said first open end to receive illumination from said source of illumination positioned within the interior of said cylinder; said lens receiving means being disposed on said liquid receiving means to extend outwardly of said first end of said housing means; and said source of illumination comprises electric light means positioned within said cylinder to selectively direct illumination toward said wall portion of said liquid receiving means.
Claim 8
Dependent Claim 42 words
Apparatus as in claim 6, further comprising: battery receptacle means contained within said partially hollow cylinder and having battery engaging elements; and electric switch means in controlling circuit with said electric light means and battery engaging elements of said battery receptacle means.
Claim 9
Dependent Claim 60 words
Apparatus as in claim 7, further comprising a pocket clip means secured to the exterior of said cylinder to enable the cylinder to be removably clipped to a sheet of material; and said electric switch means being operatively associated with said pocket clip means to enable said electric light means to be actuated by manipulation of the pocket clip means.
Claim 10
Dependent Claim 37 words
Apparatus as in claim 6, further comprising at least one lens storage receptacle disposed in said cylinder adjacent said second end thereof; and closure means associated with said lens storage receptacle to selectively retain a lens therein.
Claim 11
Dependent Claim 59 words
A contact lens inserter comprising contact lens receiving means shaped to conform to the convex surface of the contact lens, electric light means adjacent said contact lens receiving means for directing light through a contact lens positioned on said contact lens receiving means, and a translucent bottle positioned between said contact lens receiving means and said electric light means.
Claim 12
Dependent Claim 59 words
A contact lens inserter comprising contact lens receiving means shaped to conform to the convex surface of the contact lens, electric light means adjacent said contact lens receiving means for directing light through a contact lens positioned on said contact lens receiving means, and a translucent bottle positioned between said contact lens receiving means and said electric light means.
