Abstract
Abstract A card or paper-like material for use in reclassifying contact lenses has regularly arranged thereon plurality of sets of the same indicia for recording at each set in writing several specifications of a contact lens. Associated with each indicia set is a circular aperture in the card of a diameter slightly smaller than that of a contact lens so that a lens can be supported convex side down in an aperture to inhibit displacement while its specifications are being recorded at the associated indicia set. Preferably, a set of identical cards are detachably arranged in a pad having a backing member provided with apertures of the same size as, and in registration with, those in the cards.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
111 words
An article for use in reclassifying contact lenses comprising: a rectangular card containing at separate locations thereon a plurality of regularly arranged sets of the same indicia for recording at each set in writing several specifications of a concavo-convex contact lens; and a circular aperture in said card adjacent each said indicia set, said aperture being of a diameter slightly smaller than that of a contact lens, whereby a lens being reclassified and to have its specifications recorded on said card at one of said indicia sets may be positioned, convex side down, in the aperture adjacent said one set to inhibit displacement of the lens while supported on said card.
Claim 2
Dependent Claim
111 words
An article for use in reclassifying contact lenses comprising: a rectangular card containing at separate locations thereon a plurality of regularly arranged sets of the same indicia for recording at each set in writing several specifications of a concavo-convex contact lens; and a circular aperture in said card adjacent each said indicia set, said aperture being of a diameter slightly smaller than that of a contact lens, whereby a lens being reclassified and to have its specifications recorded on said card at one of said indicia sets may be positioned, convex side down, in the aperture adjacent said one set to inhibit displacement of the lens while supported on said card.
Claim 3
Dependent Claim
20 words
The structure defined in claim 1 in which the card is relatively stiff, relatively thick and made of paper material.
Claim 4
Dependent Claim
17 words
The structure defined in claim 1 in which the card is made of substantially waterproof paper-like material.
Claim 5
Dependent Claim
55 words
The structure defined in claim 1 in which the indicia sets and apertures are spaced inwardly of the side and bottom edges of the card to provide margins engageable by the fingers of a recorder to restrain the card against movement while writing thereon without interference with the indicia or lenses supported on the card.
Claim 6
Dependent Claim
32 words
The structure defined in claim 1 in which the apertures are of two different sizes for accommodating lenses in a range of larger diameters and lenses in a range of smaller diameters.
Claim 7
Dependent Claim
52 words
A pad comprising: a stack of identical cards as defined in claim 1; a card-like relatively thick backing member for said stack having apertures therein of the same size as, and aligned with, the apertures in said cards; and means detachably securing said cards and backing member together along their top edges.
