A corrective lens that is removably adherent to, and substantially in contact with, a pane of a pair of spectacles without the use of a mechanical retention device, and that 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. In a preferred embodiment, the corrective lens comprises a flexible plastic capable of conforming to a variety of surface shapes and of adhering via tactile interactions to the pane without the use of an adhesive. Also, a pair of spectacles that comprise a corrective lens securely adhered to a pane of a pair of spectacles without the use of a mechanical retention device. A method of producing a cosmetically appealing pair of spectacles is also disclosed. The method comprises adhering a corrective lens to at least one pane of a pair of spectacles without the use of a mechanical retention device.
A pair of spectacles comprising a corrective lens removably adhered to a substantially curved pane of the pair of spectacles, the corrective lens having a nominal magnifying power and comprised of clear elastomeric material, the corrective lens removably adherent to a pane of a rear surface of a pair of spectacles, the corrective lens having, before it is adhered to the pane, a non-Fresnel convex surface and a non-Fresnel non-concave surface, and comprising a corrective lens material having a refractive index such that the nominal magnifying power of the corrective lens is produced solely by cooperation of the refractive index with the corrective lens surfaces, and the lens material having a flexibility such that the corrective lens is conformable to a variety of shapes of the rear surface of the pane;
A method of producing a cosmetically appealing pair of optically magnified, substantially curved lens spectacles comprising the steps of:
A corrective lens having a nominal magnifying power and comprised of clear elastomeric material, the corrective lens removably adherent to a substantially curved rear surface of a pane of a pair of spectacles, the corrective lens having, before it is adhered to the pane, a non-Fresnel convex surface and a non-Fresnel non-concave surface, and comprising a lens material having a refractive index such that the nominal magnifying power of the corrective lens is produced solely by cooperation of the refractive index with the corrective lens surfaces, and the corrective lens material having a flexibility such that the corrective lens is conformable to a variety of shapes of the rear surface of the pane;
