Abstract: The present invention is directed to a method of manufacturing spectacle lens eyewear using a block mold, front and back optical inserts, front and back optical insert gaskets, a protractor insert, a closing mechanism and a preformed frame, the method comprising the steps of: selecting a front optical insert from a look up table or computer program product and assembling the insert into the block mold; selecting a front optical insert gasket and assembling the gasket onto the front optical insert; assembling the frame front onto the front optical insert gasket; selecting a back optical insert gasket and assembling the gasket onto the back side of the frame front; selecting a back optical insert from a look up table or computer program product and assembling the insert onto the back optical insert gasket; assembling the protractor insert and adjusting the position of the back optical insert to the axis indicated on a look up table or computer program product; assembling the mold closing mechanism and securing

Abstract: The present invention is directed to a non-deforming contact lens for keratoconus patients comprising a central zone having a displaced central zone. In particular, the central zone is displaced from the geometric center of the lens. The shape of the central zone is egg or spoon-shaped and is rotationally asymmetrical with one semi-meridian that is shorter than a corresponding semi-meridian. An intermediate transition zone is formed integral with the periphery of the central zone, and a peripheral zone is formed integral with the periphery of the intermediate transition zone, forming a round contact lens.

Abstract: The present invention provides a multifocal contact lens comprising a central contact lens area having a size, a position, and an optical power; an outer contact lens area having a size, a position, and an optical power; wherein the size, the position, and the optical power of the central contact lens area and the outer contact lens area are determined according to a measurement of the size of the pupil under a first light condition, a measurement of the reactivity of the pupil under a varying light condition or a varying focal demand, and a measurement of movement of the pupil under a varying light condition or a varying focal demand.
