Abstract
Primary and auxiliary lens assemblies are provided that allow a wearer easy usage with a reduced risk of misalignment or detachment through the use of micromagnets. Conventional magnetic auxiliary lens assemblies are difficult to manufacture and functionally limited due to the limitations of conventional magnets and the composition of the auxiliary frames. The improved lens assemblies disclosed herein instead employ high strength micromagnets advantageously aligned and embedded in the auxiliary lens frame to improve the ease and reliability of coupling to a primary frame, and to provide aesthetic and functional advantageous over the known art.
