Abstract
The disclosure relates to an eyeglass lens, including: a first lens part affixed to a second lens part, with a cylindrically-shaped interface therebetween; and a thin film interposed between the first and second lens parts at the cylindrically-shaped interface. The disclosure also relates to method of manufacturing an eyeglass lens, the method including: interposing a thin film between a first lens part and a second lens part, at a cylindrically-shaped interface between the first and second parts.
Claims16
An eyeglass lens, comprising:
- a first lens part affixed to a second lens part, with a cylindrically-shaped interface therebetween;
- and
- a thin film interposed between the first and second lens parts at the cylindrically-shaped interface, wherein the thin film comprises a holographic optical element recorded to compensate for an optical power of the cylindrically-shaped interface.
A method of manufacturing an eyeglass lens, the method comprising:
- interposing a thin film between a first lens part and a second lens part, at a cylindrically-shaped interface between the first and second parts, wherein the thin film comprises a photosensitive material, the method further comprising:
- recording a hologram on the photosensitive material to form a holographic optical element and wherein the step of recording a hologram on the photosensitive material comprises:
- providing the photosensitive material on a planar substrate;
- and
- recording the hologram on the photosensitive material when on the planar substrate, the hologram being recorded so as to compensate for an optical power of the cylindrically-shaped interface.
A method of manufacturing an eyeglass lens, the method comprising:
- interposing a thin film between a first lens part and a second lens part, at a cylindrically-shaped interface between the first and second parts, wherein the thin film comprises a photosensitive material, the method further comprising:
- recording a hologram on the photosensitive material to form a holographic optical element and wherein the step of recording a hologram on the photosensitive material comprises:
- applying the photosensitive material to the cylindrically-shaped interface;
- and
- recording the hologram on the photosensitive material when on the cylindrically-shaped interface.
