    摘要: Aspects of the present invention provide multifocal lenses having one or more multifocal inserts comprising one or more diffractive regions. A diffractive region of a multifocal insert of the present invention can provide a constant optical power or can provide a progression of optical power, or any combination thereof. A multifocal insert of the present invention can be fabricated from any type of material and can be inserted into any type of bulk lens material. A diffractive region of a multifocal insert of the present invention can be positioned to be in optical communication with one or more optical regions of a host lens to provide a combined desired optical power in one or more vision zones. Index matching layers of the present invention can be used to reduce reflection losses at interfaces of the host lens and multifocal insert.

    摘要: An embryonic optical apparatus including a first lens component including a first surface and a second surface on an opposite side of the first lens component from the first surface, and a second lens component comprising a flexible element, wherein the flexible element of the second lens component comprises a first region that is variably movable towards and away from the first surface, thereby dynamically adjusting an optical power of the embryonic optical apparatus with respect to a light path through the first region and the first surface, and wherein the embryonic optical apparatus is configured such that at least a portion of the second surface is permanently alterable to permanently define an optical power of the first lens at least a second region of the second surface, the second region being optically aligned with the first region, thereby resulting in a prescription-quality ophthalmic optical apparatus.

    摘要: Embodiments of the present invention relate to a multifocal lens having a mostly spherical power region and a progressive optical power region. Embodiments of the present invention provide for the proper alignment and positioning of each of these regions, the amount of optical power provided by each of the regions, the optical design of the progressive optical power region, and the size and shape of each of the regions. The combination of these design parameters allows for an optical design having less unwanted astigmatism and distortion as well as both a wider channel width and a shorter channel length compared to conventional PALs. Embodiments of the present invention may also provide a new, inventive far-intermediate distance zone and may further provide for increased vertical stability of vision within a zone of the lens.
