Patent ID: 7278732

Claim:
Eyewear, comprising: a frame having rims, a nose piece and temples, wherein said temples position said frame about the face of a wearer; and a first lens and a second lens, each having a lug, said lugs providing a pivot mount for said lenses to said nose piece, said nose piece having a pivot axis, whereby said lenses may be selectively moved between first positions and second positions about said nose piece, said first positions locating said lenses generally in positions in front of the eyes of said wearer for viewing, and said second positions locating said lenses away from said positions in front of said eyes and exposing regions around said eyes; wherein said lugs are inter-engaging portions providing cooperation between said first lens and said second lens, whereby a selective movement of said first lens from said first position to said second position cooperatively engages said second lens prior to said first lens reaching said second position to move said second lens from said second position to said first position; wherein said pivot axis is generally normal to said rims and generally parallel to said temples; wherein said selective movement is a rotation about said pivot axis; and wherein said inter-engaging portions arrests the rotation of said first lens from said first position to said second position thereby creating an angle of less than approximately 90 degrees between a top cam surface of each of said first and second lenses, whereby only one lens is in said second position at a time.
