Abstract

Interchangeable single-lens glasses include a mount with a front lens-holding frame having a bar extended at supraciliary arches between opposed lateral ends of the frame, and means for removable retention on the bar a single-lens structure extending frontally between the ends. The means for retaining the lens structure on the bar include, at each of the lateral ends, at least a respective first magnet or ferromagnetic material element provided on the frame and a second magnet or ferromagnetic material element provided on the lens in a corresponding position, to cooperate in reciprocal magnetic attraction with the corresponding first element, and, at a central portion of the bar, proximate to a nasal rest area of the mount, a relief protruding frontally from the bar and an opening passing through the lens in a corresponding position, the relief being configured to engage the opening with relative reciprocal locking.
