1. Eyewear comprising:
a primary frame having opposed side ends and retaining at least one primary lens, a support device being operatively attached to the respective opposed side ends of the primary frame for supporting the eyewear on a user's head, and a first magnet attached to a central location of an upper part of the primary frame extending between the opposed side ends; and a secondary lens assembly removably attachable to a front of the primary frame, the secondary lens assembly including:
a secondary frame retaining at least one secondary lens, the secondary frame having an upper part extending between opposed side ends of the secondary frame;a connector affixed to a central location of the upper part of the secondary frame and including a second magnet to allow the connector to be removably attached to a central location of the upper part of the primary frame by magnetic forces interacting between the first and second magnets, wherein the connector includes a hook and the primary frame includes a recess at the central location, the hook being slidable downwardly relative to the recess to engage with the recess for positioning the secondary lens assembly into a position of attachment with respect to the primary frame; andwherein in said position of attachment the first and second magnets are within a magnetic interaction area between the first and second magnets and are prevented from being fully aligned one with another when the hook is fully engaged with the recess.
