Eyewear frames with magnetic lens attachements
First Claim
1. A lens apparatus for removably mounting a primary lens to an eyeglass frame comprising a lens and at least one lens magnetic member, the lens comprising:
- a lens front surface having a front circumferential edge;
a lens rear surface having a rear circumferential edge spaced a distance from said front circumferential edge;
a lens thickness spaced between the front lens surface and the rear lens surface;
a lens edge surface spaced between the front circumferential edge and the rear circumferential edge; and
a cavity extending through the lens thickness, the cavity having a proximal cavity portion proximal to the circumferential edge and having a first cavity dimension; and
the cavity having a distal cavity portion distal from the circumferential edge and having a second cavity dimension, wherein the second cavity dimension is larger than the first cavity dimension;
wherein the at least one lens magnetic member comprises;
a magnetic member front surface;
a magnetic member rear surface;
a magnetic member edge surface;
whereina first portion is sized to fit within the first cavity portion; and
a second portion is sized to fit within the second cavity portionwherein the magnetic member front surface is substantially flush with the lens front surface, the magnetic member rear surface is substantially flush with the lens rear surface and the magnetic member edge surface is substantially flush with the lens edge surface.

Abstract
The present invention illustrates various methods of attaching a pair of eyeglass lenses or a lens shield to an eyeglass frame using magnets or magnetically attractive material. The magnetic attachment methods are beneficial because they allow the user to have interchangeable lenses or shields for indoor and outdoor use, enhancing their visual acuity during work or play. The lenses may be tinted, prescription, protective eyewear, or plano. The magnetic lenses are convenient and user friendly, allowing intuitive, tool-less interchangeability with no need to twist or stress the frame. These methods of attachment require no specific instructions or tools when the user replaces lenses.

8. An eyeglass assembly comprising a primary eyeglass frame adapted for removable mounting of a primary lens thereto, the assembly further comprising:
-
at least one primary lens having a front surface, a rear surface, a circumferential edge thickness, an edge surface, and at least one lens cavity extending through the circumferential edge thickness, the at least one lens cavity having a proximal cavity portion proximal to the circumferential edge and having a first lens cavity dimension, and a distal cavity portion distal to the circumferential edge and having a second lens cavity dimension larger than the first lens cavity dimension; a primary eyeglass frame comprising at least one partial lens rim portion comprising; a front frame portion having a front frame surface, a rear frame portion separated a distance from and opposing the front frame surface, a connecting frame portion connecting the front frame portion and the rear frame portion, the connecting portion comprising; a mounting surface; and at least one frame cavity extending through the connecting frame portion, the at least one frame cavity having a first frame cavity portion proximal to the mounting surface having a first frame cavity dimension, and a second frame cavity portion distal from the mounting surface having a second frame cavity dimension larger than the first frame cavity dimension; at least one lens magnetic member configured to closely engage the at least one lens cavity such that a lens magnet front surface is substantially flush with the lens front surface, a lens magnet rear surface is substantially flush with the lens rear surface and a lens magnet edge surface is substantially flush with the lens edge surface; and at least one frame magnetic member configured to closely engage the at least one frame cavity such that at least a portion of a frame magnetic member edge surface is substantially flush with the mounting surface.
