Eyewear having interchangeable lenses

Eyewear having interchangeable lenses comprising

• a pair of lenses each having a rim around its peripheral edge, each of said rims having a pair of projections extending outwardly from opposite sides thereof defining a distal projection and a proximate projection,
• a top frame having a pair of lens receiving sections and a bearing member between said receiving sections having means for releasably securing said proximate projections on each lens, each of said sections including a downwardly opened groove for removably receiving the upper edge of said rims and a recess area near its distal end to engage said distal projection,
• a bridge having an inverted generally U-shaped member and a connecting member attaching said U-shaped member to said top frame, said U-shaped member having sidewardly opened grooves on opposite sides thereof for receiving the edge of each of said rims, and
• rearwardly extending temples pivotally connected to opposite ends of said top frame,
• wherein said bridge is movable from a first position which secures the bottom edge of said proximate projection on each of said rims to a second position which releases the bottom edge of said proximate projection and allows removal of said lenses from said top frame.

Eyewear having a top frame, temples and a pair of interchangeable lenses comprising

• (a) sidewardly extending projections on opposite ends of said lenses to provide a distal projection and a proximate projection on each lens,
• (b) recess areas at the distal ends of said top frame for receiving said distal projection of each lens, and a downwardly opened elongated groove on bottom edge of said top frame for removably receiving upper edges of said lenses,
• (c) a movable nose bridge centrally attached to said top frame by a connecting member affixed to an inverted generally U-shaped member,
• (d) a bearing member centrally attached to said top frame, said bearing member having means for supporting the top edge of each of said proximate projections,
• wherein said nose bridge is movable from a first position allowing insertion of said distal projection and said lenses into said top frame and said proximate projection against a shoulder of said beating member, to a second position against said beating member which secures the bottom edge of said proximate projection of each lens against the top edge of said inverted generally U-shaped member.
