Abstract
The present invention relates to eyewear, and in particular, to a design for a primary lens assembly combinable with a secondary lens assembly. The primary lens assembly has a slotted extension design. The auxiliary lens assembly has extensions insertable into the slots of the primary extensions. The auxiliary lens assembly is horizontally insertable into the primary lens assembly. The primary and/or auxiliary lens assemblies may have magnets. Alternatively, the primary and/or auxiliary lens assemblies may have compressible bushings to permit an interference fit of the assemblies. The design permits easier attachment and prohibits undesired disengagement of auxiliary lens assembly from primary frame assembly.
