The present invention is directed to a magnifying and/or corrective lens or optical element that may be removably adhered to a plano lens, such as the pane of a of a pair of spectacles or sunglasses, without the use of a mechanical retention device or other mechanical means for retention. The lenses are injection-molded from an aliphatic thermoplastic polyurethane, and capable of conforming to a variety of surface shapes and of adhering via tactile interactions to a plano lens without the use of an adhesive. The lenses may be securely but releasably secured to the surface of a plano lens by finger pressure alone due to their inherent molecular surface-adhesion characteristics to readily create magnifying or corrective lenses, or to modify the magnification or correction of a pair of sunglasses or plano eyeglasses. The lens of the present invention has at least one curved surface and a refractive index such that the curved surface and the refractive index cooperatively produce a nominal magnifying power. The present invention is also directed to a pair of spectacles that comprise a magnifying and/or corrective lens securely adhered to a pane of a pair of spectacles without the use of a mechanical retention device.
