Abstract
The present invention discloses a unique and novel system for attaching an auxiliary lens assembly to a primary lens assembly in which the attachment includes two alternative positions, a lowered position and a raised position. In the lower position, the person wearing the eyewear system views through both the primary lenses and auxiliary lenses. In the raised position, the person wearing the eyewear system views only through the primary lenses. As a further option, the auxiliary lens assembly is easily removable from the primary lens assembly, allowing for separate storage of the auxiliary lens assembly when not needed. Slotted extensions on the primary lens frame receive retainers attached to auxiliary extensions on the auxiliary lens assembly. Each auxiliary extension has a rocker pivotally attached to a keyseat. An internal spring urges the rocker into snap alignment with the surfaces of the keyseat.
