The treatment zone includes a base curve and a reverse curve formed on outside of base curve. The positioning zone includes an alignment curve and a peripheral curve located outside alignment curve. A center point is formed in center of base curve, the junction of base curve and reverse curve forms a first point of intersection, the junction of reverse curve and alignment curve forms a second point of intersection, and the junction of alignment curve and peripheral curve forms a third point of intersection. The linear distance between the center point and the cornea of the preset eyeball is between 9 μm˜21 μm. The linear distance between the first point of intersection and the cornea of the preset eyeball is between 89 μm˜189 μm.

The dome-shaped flexible sheet of material includes: (a) a non-optic zone comprising the periphery of the dome-shaped flexible sheet of material, and including: an upper peripheral zone comprising an upper part of the periphery of the dome-shaped flexible sheet of material, and a lower peripheral zone comprising a lower part of the periphery of the dome-shaped flexible sheet of material. The curvature of the dome-shaped flexible sheet of material is dynamically adaptable, by virtue of at least one of the upper and lower peripheral zones being structured to laterally expand and contract; and (b) an optic zone disposed in an area of the dome-shaped flexible sheet of material that lies between the upper and lower peripheral zones, wherein the optic zone is configured to align with a visual axis of the eye.

Abstract: A method for applying a surface pattern on a surface of a spectacle lens substrate includes the following steps: providing a spectacle lens substrate having a polymeric lens material, providing a composition containing a swelling agent, applying a pattern of the composition on the surface of the spectacle lens substrate, and allowing for diffusion of the swelling agent from the composition into the lens material. Moreover, a spectacle lens substrate has a polymeric lens material and exhibits a surface pattern on a surface of the spectacle lens substrate. The polymeric lens material includes a swelling agent at positions forming the surface pattern, and a spectacle lens substrate contains a polymeric lens material, wherein the spectacle lens substrate exhibits a pattern of a composition containing a swelling agent applied on a surface of the spectacle lens substrate.

Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.

Abstract: A phase-adjusting element configured to provide substantially liquid-invariant extended depth of field for an associated optical lens. One example of a lens incorporating the phase-adjusting element includes the lens having surface with a modulated relief defining a plurality of regions including a first region and a second region, the first region having a depth relative to the second region, and a plurality of nanostructures formed in the first region. The depth of the first region and a spacing between adjacent nanostructures of the plurality of nanostructures is selected to provide a selected average index of refraction of the first region, and the spacing between adjacent nanostructures of the plurality of nanostructures is sufficiently small that the first region does not substantially diffract visible light.

Abstract: A contact lens and a method for treating an eye with myopia is described. The contact lens includes an inner optic zone and an outer optic zone. The outer optic zone includes at least a portion with a first power, selected to correct distance vision. The inner optic zone has a relatively more positive power (and add power). In some embodiments the add power is substantially constant across the inner optic zone. In other embodiments the add power is variable across the inner optic zone. While in some embodiments the inner optic zone has a power designed to substantially eliminate lag of accommodation in the eye with myopia, in other embodiments, the add power may be higher.
