摘要： Embodiments of the present invention relate to a multifocal lens having a diffractive optical 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.

摘要： An adapter for a spectacle frame is disclosed which is configured for enabling the spectacle frame to operate and control electro-active lenses housed therein. In particular, the spectacle frame may allow electro-active lenses housed therein to focus and be controlled both automatically and manually with heretofore unrealized results.

摘要： Devices suitable for charging implanted electronic devices are provided. A device suitable for charging one or more implanted electronic devices, specifically implanted ophthalmic devices, may include a wearable frame, one or more conductive coils, and a power source to provide a current to the conductive coil. When placed in proximity to an implanted device having a second conductive coil, the current in the conductive coil causes an induced current in the second conductive coil, which may be used to power the implanted electronic device.

摘要： Aspects of the present invention provide multiple-layer (multi-layer) composite lenses comprising two or more materials and methods for making the same. A multi-layer composite lens of the present invention can use multiple surfaces (internal or external) to form optical elements that can contribute to a total desired add power. The multiple contributing optical elements can be aligned so as to be in optical communication to form multiple stable vision zones to enhance optical performance and the vision experience of the wearer. Distributing the total desired add power across multiple appropriately aligned optical elements that are in optical communication with one another can reduce the total distortion of the lens, minimize the number of optical discontinuities introduced, can reduce optical power jump as experienced by the wearer's eye when traversing any discontinuity, and can reduce the visibility of any introduced optical discontinuity as perceived by an observer looking at the wearer.

摘要： A lens system is presented having a diffractive optical power region. The diffractive optical power region has a plurality of concentric surface relief diffractive structures. A greater portion of light incident on a diffractive structure near the center point contributes to the optical power than light incident on a diffractive structure peripherally spaced therefrom.

摘要： An ophthalmic lens is presented in which the lens includes a progressive addition region and a dynamic optic. The dynamic optic and the progressive addition region are in optical communication. The progressive addition region has an add power which Is less than a user's neat viewing distance add power. The dynamic optic, when activated, provides the additional needed optical power for the wearer to see clearly at a near distance. This combination leads to the unexpected result that not only does the wearer have the ability to see clearly at intermediate and near distances, but the level of unwanted astigmatism, distortion, and vision compromise are reduced significantly.

摘要： An electro-active lens has a first substrate with a surface relief diffractive topological profile and a second substrate positioned opposite to the first substrate having a substantially smooth topological profile. A first electrode is positioned along the surface relief diffractive topological profile of the first substrate and a second electrode is positioned between the first electrode and the second substrate. The smallest distance between the electrodes is less than or equal to about 1 micron An electro-active material is positioned between the first and second electrodes and a first insulating layer is positioned between the first and second electrodes.

摘要： Embodiments of the present invention relate to an electro-active element having a dynamic aperture. The electro-active element provides increased depth of field and may be used in a non- focusing ophthalmic device that that is spaced apart from but in optical communication with an intraocular lens, a corneal inlay, a corneal onlay, a contact lens, or a spectacle lens that provide an optical power. The electro-active element provides increased depth of field and may also be used in a focusing or non-focusing device such as an intraocular optic, an intraocular lens, a corneal inlay, a corneal onlay, or a contact lens which may or may not have an optical power. By changing the diameter of dynamic aperture either increased depth of field or increased light reaching the retina may be achieved.

摘要： Embodiments of the present invention relate to a cholesteric liquid crystalline material which may be usable in an electro-active element for providing fail safe operation, polarization insensitivity, low electrical power consumption requirements, and a small number of electrical connections. The cholesteric liquid crystalline material may be usable in an electro-active element for providing a diffractive efficiency or focusing efficiency above 90% in an activated state of the electro-active element and a diffractive efficiency or focusing efficiency below 10% in a deactivated state of the electro-active element.
