    摘要： A mechanism allows for changing the optical strength of a liquid-filled lens having a cavity filled with fluid. A reservoir contains additional fluid and is in fluid communication with the cavity, and the mechanism draws fluid from the reservoir into the cavity or pulls fluid from the cavity back into the reservoir, whereby a change in the amount of fluid within the lens cavity changes the lens's optical strength. A membrane seals the reservoir, and a plunger impinges upon the membrane. A movement device, such as a barrel screw or lever, moves the plunger in a controlled manner toward the membrane to increase pressure within the reservoir and thereby force fluid out of the reservoir into the lens cavity, and away from the membrane to decrease pressure within the reservoir and thereby withdraw fluid from the lens cavity and into the reservoir.

    摘要： An optical and mechanical design of a sealed, non-round fluid-filled lens capable of providing variation of optical power. The fluid lens includes at least three optical components: at least one mostly rigid optical disc, at least one mostly flexible optical membrane and a layer of a transparent fluid that is in communication via a fluid channel with a reservoir of excess fluid contained in a reservoir that can be accessed to augment the fluid volume inside the fluid lens to change the power of the fluid lens. The fluid lens is capable of providing correction of spherical and astigmatic errors, and utilizes contoured membranes to minimize image aberrations.

    摘要： The present invention provides multifocal lenses containing at least four zones of different refractive power. The zones are positioned such that the wearer is able to use the inferior-most portion of the lens to more clearly, as compared to conventional multifocal lenses, view objects at distances more than 45 cm from the eye.

    摘要： An optical lens of an acrylic polymer having an outermost surface modified in morphology to possess desired characteristics of low surface energy and high biological inertness. The modified surface is achieved by removing only molecular level irregularities in the outermost surface of an acrylic polymer optical lens body. The surface removal and smoothing process involves the steps of surface preparation and surface passivation. In surface preparation, the surface of the lens body is treated to render it wettable by a surface passivation reagent. In surface passivation, the surface prepared optical lens body is immersed in a surface passivation reagent which removes weakly bound water molecules from the outermost surface of the lens body and reorganizes or smoothes at the molecular level irregularities at the surface of the optical lens body.
