Claim 9

The eyeglasses of claim 1 further including a plurality of lens pairs, each of said lens pairs having a tint that differs from the tint of each other lens pair.

Claim 10

The eyeglasses of claim 1 wherein said frame is fabricated from a resiliently compliant material so that said frame may be deformed to allow said lenses to be installed in and removed from respective fame sections.

Claim 11

The eyeglasses of claim 1 wherein said lenses are fabricated from a resiliently compliant material so that said lenses may be deformed to allow said lenses to be installed in and removed from respective fame sections.

Claim 12

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.

Claim 13

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.

Claim 14

The eyeglass frame of claim 11 wherein said lens attachment clips are positioned so that said attachment clips contact the outer surface of respective lenses when said lenses are positioned between said clips and said frame members.

Claim 15

The eyeglass frame of claim 11 wherein said first and third lens attachment clips extend along the upper and lower frame members of said frame.

Claim 16

The eyeglass frame of claim 11 wherein said second and fourth lens attachment clips extend along the upper and lower frame members of said frame.

Claim 17

The eyeglass frame of claim 11 wherein said first, second, third, and fourth lens attachment clips extend along the upper and lower frame members of said frame.

Claim 18

The eyeglass frame of claim 11 wherein said second and fourth lens attachment clips extend along only respective upper frame members of said frame.

Claim 19

The eyeglass frame of claim 11 wherein said frame members are fabricated from a resiliently compliant material so that said frame members may be deformed to allow said lenses to be installed in and removed from said frame.

Claim 22

The method of claim 18 wherein said lens is removed by exerting a force on an edge of said lens adjacent said upper frame member in a direction extending toward said lower frame member and installed by exerting a force on an edge of said lens adjacent said lower frame member in a direction toward said upper frame member.

Claim 23

The method of claim 18 wherein said lens is removed by exerting a force on an edge of said lens adjacent said lower frame member in a direction extending toward said upper frame member and installed by exerting a force on an edge of said lens adjacent said upper frame member in a direction toward said lower frame member.

Claim 24

The method of claim 18 wherein said forces are exerted a on the edge of said lens at a location that is closer to said inner lens attachment clip than it is to said outer lens attachment clip.

Claim 25

The method of claim 18 wherein said lens is installed by placing an edge of said lens between said outer attachment clip and at least one of said frame members and then exerting a force on the edge of said lens at a location that is closer to said inner lens attachment clip than it is to said outer lens attachment clip.
