and a transparent layer coupled to an edge of the deformable lens that includes a plurality of light sources incorporated within the transparent layer and configured to selectively output the radiation that causes the curvature of the surface of the deformable lens to change from the first curvature to the second curvature. ### Claim 2 (depends on 1) The optical device of claim 1, wherein the photoswitch material is spiropyran. ### Claim 3 (depends on 1) The optical device of claim 1, wherein the deformable lens is a meniscus lens having a convex surface and a concave surface that meet at the edge. ### Claim 4 (depends on 1) The optical device of claim 1 wherein the plurality of light sources are arranged to allow at least a portion of a visible light from a second light source to pass through the transparent layer to the deformable lens. ### Claim 5 (depends on 1) The optical device of claim 1, wherein a first portion of the plurality of light sources output the radiation at a first intensity and a second portion of the plurality of light sources output the radiation at a second intensity. ### Claim 6 An optical device comprising: a deformable lens having a photoswitch material that, when irradiated by a radiation, causes a curvature of a surface of the deformable lens to change from a first curvature to a second curvature based on an intensity of the radiation; a waveguide attached to an edge of the deformable lens and having diffraction gratings adjacent to the deformable lens; and a first light source configured to output the radiation into the waveguide that outputs a portion of the radiation to the deformable lens via the diffraction gratings. ### Claim 7 (depends on 6) The optical device of claim 6, wherein the waveguide has a first side and a second side being opposite of the first side, the edge of the deformable lens being attached to the first side; and a second light source being located adjacent to the second side and configured to output visible light that travels through the waveguide to the deformable lens. ### Claim 8 (depends on 7) The optical device of claim 7, wherein the first light source is adjacent to the first side. ### Claim 9 (depends on 6) The optical device of claim 6, wherein the waveguide has a first side and a second side being opposite of the first side, the edge of the deformable lens being attached to the first side;
