The present invention illustrates various methods of attaching a pair of eyeglass lenses or a lens shield to an eyeglass frame using magnets or magnetically attractive material. The magnetic attachment methods are beneficial because they allow the user to have interchangeable lenses or shields for indoor and outdoor use, enhancing their visual acuity during work or play. The lenses may be tinted,prescription, protective eyewear, or plano. The magnetic lenses are convenient and user friendly, allowing for tool-less interchangeability with no need to twist or stress the frame. These methods ofattachment require no specific instructions or tools when the user replaces lenses.
