1. Eyeglasses having interchangeable lenses, comprising:
- a pair of eyeglass lenses;
a frame having a bridge interconnecting a pair of frame sections, each frame section including upper and lower frame members extending from said bridge to respective attachment areas, each of said frame sections further including an inner lens attachment clip extending from said bridge part of the way toward said attachment area and an outer lens attachment clip extending from said attachment area part of the way toward said bridge so that said inner and outer lens attachment clips are separated from each other by a gap, the lens attachment clips of each frame section retaining respective lenses between said clips and at least one of said frame members, said frame or said lenses being fabricated from a resiliently compliant material so that said frame or lenses may be deformed to allow said lenses to be installed in and removed from respective fame sections; and
a securing device attached to the attachment areas of said frame sections to retain said frame on the face of a wearer.

Abstract
Eyeglasses having interchangeable lenses which are held in place by inner and outer lens attachment clips mounted at the bridge and temple, respectively, of the frame. The frame and/or lens is resilient so that the frame or lens can resiliently deform to allow the lenses to slide from beneath the lens attachment clips, yet the frame securely holds the lenses in place during use.

11. An eyeglass frame adapted to receive interchangeable lenses, said frame comprising:
-
a bridge; a first pair of upper and lower frame members extending from said bridge to a first attachment area; a second pair of upper and lower frame members extending from said bridge to a second attachment area, said second pair of upper and lower frame members extending from said bridge in a direction opposite the direction that said first pair of upper and lower frame members extend from said bridge, said frame members being fabricated from a resiliently compliant material; a first lens attachment clip extending from said bridge part of the way toward said first attachment area; a second lens attachment clip extending from said first attachment area part of the way toward said bridge so that said first and second lens attachment clips extend toward each other but are separated from each other by a gap, the first and second lens attachment clips being adapted to retain a lens between said clips and at least one of said frame members; a third lens attachment clip extending from said bridge part of the way toward said second attachment area; and a fourth lens attachment clip extending from said second attachment area part of the way toward said bridge so that said third and fourth lens attachment clips extend toward each other but are separated from each other by a gap, the third and fourth lens attachment clips being adapted to retain a lens between said clips and at least one of said frame members. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of changing eyeglass lenses in an eyeglass frame, said frame having a bridge interconnecting a pair of frame sections, each frame section including upper and lower frame members extending from said bridge to respective attachment areas, each of said frame sections further including an inner lens attachment clip extending from said bridge part of the way toward said attachment area and an outer lens attachment clip extending from said attachment area part of the way toward said bridge so that said inner and outer lens attachment clips are separated from each other by a gap, said method comprising:
-
removing a lens from each of said frame sections by exerting a force on an edge of said lens adjacent one of said frame members in a direction extending generally parallel to a surface of said lens and toward the other of said frame members while allowing said frame members and/or said lens to deform thereby removing said lens from between said lens attachment clips and said frame members; and installing another lens in each of said frame sections by placing an edge of said lens between said attachment clips and said frame sections and then exerting a force on an edge of said lens adjacent the other of said frame member in a direction extending generally parallel to a surface of said lens and toward said one frame member while allowing said frame members and/or said lens to deform thereby installing said lens in said frame between said lens attachment clips and said frame members. - View Dependent Claims (19, 20, 21, 22)
