| Abstract: |
An attachment for eyeglass frames which permits the wearer to quickly replace lenses without the use of optical hand tools or equipment, and which does not require the dexterity usually associated in working with miniature optical parts. The invention is permanently affixed to the eyeglasses, eliminating the possibility of loss, damage or disconnection. The invention is designed for use in instances where changing light conditions necessitate the need for tinted or sunglasses but where carrying additional frames is neither practical or desireable.

I claim:
1. Eyeglasses which allow for the removal and replacement of lenses comprising;
- a pair of lenses,
- a pair of temple arms,
- a pair of split frames, each having a medial side and a lateral side, wherein each frame is split on said lateral side forming an upper lateral frame portion and a lower lateral frame portion, each of said lateral frame portions having an end,
- a bridge attached to and connecting the medial side of each of said pair of split frames, and
- a pair of attachment means for attaching each of said temple arms to said upper and lower lateral frame portions of each of said pair of split frames, wherein each said attachment means secures one of said lenses within one of said split frames by bringing together said ends of said upper and lower lateral frame portions when said temple arm is positioned perpendicular to a first vertical plane containing said lenses, said split frames and said bridge, and wherein each said attachment means allows one of said lenses to be removed from one of said split frames and replaced by separating said ends of said upper and lower lateral frame portions when said temple arm is rotated to a position parallel to said first vertical plane and perpendicular to a second horizontal plane which is perpendicular to said first vertical plane and extends through said bridge and a horizontal cross section of said lenses and said split frames.
