An eyeglass for maintaining geometry and optical quality of first and second lenses supported by the eyeglass, the eyeglass comprising: a frame adapted to be carried by the head of a wearer, the frame extending at least partially about a perimeter of the first and second lenses; a first support member pivotably attached to the frame at a first joint such that the first support member can be pivoted relative to the frame between a retaining position and an open position, the first support member being moveable to the retaining position to capture at least a portion of the perimeter of the first lens for mounting the first lens in the path of the wearer's field of view; a second support member pivotably attached to the frame at a second joint such that the second support member can be pivoted relative to the frame between a retaining position and an open position, the second support member being moveable to the retaining position to capture at least a portion of the perimeter of the second lens for mounting the second lens in the path of the wearer's field of view; first and second securing members (340, 342) being movable relative to the frame between engaged positions and disengaged positions, the first and second securing members (340, 342) being in engaged positions to secure the respective first and second support members (310, 312) in the retaining positions for securing the first and second support members (310, 312) relative to the frame, wherein the first and second securing members (340, 342) are nosepiece components configured to contact the wearer's nose to support the eyeglass; and wherein, upon disengagement of the first securing member from the frame, the first supporting member is capable of being pivoted to an open position, releasing the first lens from the frame, and upon disengagement of the second securing member from the frame, the second supporting member is capable of being pivoted to an open position, releasing the second lens from the frame; wherein the first and second support members (310, 312) are movable separately from each other and the first and second securing members (340, 342) are movable separately from each other. a frame adapted to be carried by the head of a wearer, the frame extending at least partially about a perimeter of the first and second lenses; a first support member pivotably attached to the frame at a first joint such that the first support member can be pivoted relative to the frame between a retaining position and an open position, the first support member being moveable to the retaining position to capture at least a portion of the perimeter of the first lens for mounting the first lens in the path of the wearer's field of view; a second support member pivotably attached to the frame at a second joint such that the second support member can be pivoted relative to the frame between a retaining position and an open position, the second support member being moveable to the retaining position to capture at least a portion of the perimeter of the second lens for mounting the second lens in the path of the wearer's field of view; first and second securing members (340, 342) being movable relative to the frame between engaged positions and disengaged positions, the first and second securing members (340, 342) being in engaged positions to secure the respective first and second support members (310, 312) in the retaining positions for securing the first and second support members (310, 312) relative to the frame, wherein the first and second securing members (340, 342) are nosepiece components configured to contact the wearer's nose to support the eyeglass; and wherein, upon disengagement of the first securing member from the frame, the first supporting member is capable of being pivoted to an open position, releasing the first lens from the frame, and upon disengagement of the second securing member from the frame, the second supporting member is capable of being pivoted to an open position, releasing the second lens from the frame; wherein the first and second support members (310, 312) are movable separately from each other and the first and second securing members (340, 342) are movable separately from each other.
