Abstract
Abstract An eyeglass attachment, for example a tinted lens, is provided with a circumferential groove which is engaged by a tension thread. A plurality of clips are mounted on the tension thread so as to be resiliently biased against the edge of the lens. The clips have outwardly extending arms with projections which engage the opposite sides of the frame of an eyeglass on which the tinted lens is to be installed.

Total Claims: 22
Claim 1
Independent Claim
126 words
An eyeglass attachment comprising: an attachment lens for installation on an existing eyeglass in registration with the lens of the eyeglass, said attachment lens having a pair of oppositely disposed sides and a circumferential edge region which extends between said sides, said attachment lens circumferential edge region being provided with a groove; an elongated elastic member extending around said circumferential edge region of said attachment lens, said elastic member being in tension and being received in said groove; and a plurality of clips, said clips being engaged by said elastic member whereby said clips are resiliently biased against said circumferential edge region of said attachment lens, said clips each having an eyeglass engagement portion spaced outwardly with respect to a first side of said attachment lens.
Claim 2
Dependent Claim
126 words
An eyeglass attachment comprising: an attachment lens for installation on an existing eyeglass in registration with the lens of the eyeglass, said attachment lens having a pair of oppositely disposed sides and a circumferential edge region which extends between said sides, said attachment lens circumferential edge region being provided with a groove; an elongated elastic member extending around said circumferential edge region of said attachment lens, said elastic member being in tension and being received in said groove; and a plurality of clips, said clips being engaged by said elastic member whereby said clips are resiliently biased against said circumferential edge region of said attachment lens, said clips each having an eyeglass engagement portion spaced outwardly with respect to a first side of said attachment lens.
