Method and apparatus for marking eyeglass lens for placement of reading segment

Abstract

An eyeglass lens appliqué device for determining placement of at least one auxiliary lens within an eyeglass lens includes a polymer sheet that can be removably disposed on the eyeglass lens, and is clingable to the eyeglass lens. The polymer sheet includes a pupil mark, and scale markings to show a distance from the pupil mark to an approximate peripheral edge of the eyeglass lens when the appliqué is disposed on an eyeglass lens.

1 . An eyeglass lens appliqué device for determining placement of at least one auxiliary lens within an eyeglass lens, comprising:
 a) a polymer sheet, removably disposable on the eyeglass lens, and clingable thereto by specific or mechanical adhesion;   b) a pupil mark, disposed on the polymer sheet, alignable with a patient's pupil; and   c) scale markings, disposed on the polymer sheet to show distance from the pupil mark to an approximate peripheral edge of the eyeglass lens.   
   
   
       2 . A device in accordance with  claim 1 , further comprising:
 an outline of at least one auxiliary lens on the polymer sheet.   
   
   
       3 . A device in accordance with  claim 2 , wherein the outline of the auxiliary lens and an area of the polymer sheet enclosed by the outline are translucent and an area around the outline of the auxiliary lens is transparent. 
   
   
       4 . A device in accordance with  claim 2 , wherein the outline of the auxiliary lens extends from a top peripheral edge of the plastic sheet, and is sized and shaped to simulate a location of an auxiliary lens on the eyeglass lens when the polymer sheet is disposed thereon, and the scale extends from a top of the polymer sheet to a bottom of the polymer sheet. 
   
   
       5 . A device in accordance with  claim 4 , wherein the outline of the auxiliary lens is substantially circular and the pupil mark is at the approximate center of the outline. 
   
   
       6 . A device in accordance with  claim 1 , wherein the pupil mark is at the approximate center of a substantially straight peripheral edge of the outline. 
   
   
       7 . A device in accordance with  claim 1 , wherein the scale markings include a plurality of substantially straight lines spaced a predetermined distance from one another, each line extending across the entire plastic sheet, and the plurality of lines extending from a top to a bottom of the plastic sheet. 
   
   
       8 . A device in accordance with  claim 1 , wherein the auxiliary lens is selected from the group consisting of a bifocal lens, a trifocal lens, a progressive lens, a multifocal lens, or combinations thereof. 
   
   
       9 . An eyeglass lens appliqué device for determining placement of a auxiliary lens within an eyeglass lens, comprising:
 a) a polymer sheet, removably disposable on the eyeglass lens, and clingable thereto by specific or mechanical adhesion; and   b) a pupil mark on the polymer sheet, an area enclosed by the pupil mark being transparent.   
   
   
       10 . A device in accordance with  claim 9 , further comprising:
 scale markings, disposed on the polymer sheet to show distance from the pupil mark to an approximate peripheral edge of the eyeglass lens.   
   
   
       11 . A device in accordance with  claim 10 , wherein the scale markings include a plurality of substantially straight lines spaced a predetermined distance from one another, each line extending across the entire polymer sheet, and the plurality of lines extending from the pupil mark to a bottom of the polymer sheet. 
   
   
       12 . A device in accordance with  claim 9 , further comprising an outline of the auxiliary lens extending from a top peripheral edge of the polymer sheet, the outline being sized and shaped to simulate a location of an auxiliary lens on the eyeglass lens when the polymer sheet is disposed thereon. 
   
   
       13 . A device in accordance with  claim 12 , wherein the auxiliary lens is selected from the group consisting of a bifocal lens, a trifocal lens, a progressive lens, a multifocal lens, or combinations thereof. 
   
   
       14 . A device in accordance with  claim 9 , further comprising:
 wherein the pupil mark includes indicia disposed on the polymer sheet selected from the group consisting of a substantially vertical line, a solid circle, an open circle, a cross hairs, a horizontal line, and combinations thereof.   
   
   
       15 . A method for determining an auxiliary lens location for an eyeglass lens, comprising:
 a) placing a pair of eyeglasses on a patient, the eyeglasses having a frame and a pair of lenses within the frame;   b) applying a removable appliqué on at least one of the eyeglass lenses, the appliqué clinging to the eyeglass lens by specific or mechanical adhesion and including a pupil mark and a distance scale;   c) adjusting placement of the appliqué to align the pupil mark with the approximate center of the patient's pupil;   d) observing the scale on the appliqué to determine a distance from the pupil mark of to an approximate perimeter of the eyeglasses frame; and   e) recording the distance.   
   
   
       16 . A method in accordance with  claim 13 , further comprising:
 adjusting placement of the appliqué based on feedback from the patient with respect to the location of an outline of the auxiliary lens disposed on the polymer sheet.   
   
   
       17 . A method in accordance with  claim 13 , wherein the step of applying an appliqué further includes removing a backing from the appliqué. 
   
   
       18 . A method in accordance with  claim 13 , wherein the removable appliqué includes a sheet of polymer material.
