    摘要: The disclosure relates to a method and apparatus for making lenses and a composition of molding material which can be utilized in the method and apparatus for molding lenses of optical quality. A monomer is used with initiators in conjunction with the molding apparatus to mold plastic lenses of optical quality without requirement for any additional polishing or grinding, except for perhaps shaping the edges. The molding material includes a composition of liquid monomer with a thermal initiator and a UV initiator each of which can be activated during the molding process. Initially, the molding forms with the liquid monomer compositions therein are heated to activate the thermal initiator and form the molding material into a gel. The gelled material is then subjected to a UV light source for completing the cure. Prepolymerized molding material can be used in some instances to avoid an intermediate step of thermal curing. Various other embodiments and apparatus are disclosed for molding plastic lens.

    摘要: An intraocular system is presented that may include an electro-active element having multiple independently controllable zones or pixels, and a controller capable of being remotely programmed. The system or element may be flexible, such that it can be folded for insertion into the eye. The system may include various energy storage and charging mechanisms to provide power to the lens and/or the controller.

    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 near 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.
