    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： A multi-focal spectacle lens is presented having far distance, intermediate distance, and near distance vision correction, in which the lens includes a progressive addition surface with a progression of optical power. The lens further includes a multi-order diffractive surface relief structure with an optical add power. The multi-order diffractive structure reduces chromatic aberration as compared to a conventional diffractive structure of equivalent optical power. The lens may also include a wavefront splitting device diffractive structure for generating multiple optical powers simultaneously. When the progressive addition surface and the multi-order diffractive surface relief structure are in optical communication an overall progression of optical add power may be provided by the combination of the progressive addition surface with the multi-order surface relief diffractive structure.
