Abstract: An apparatus for manufacturing a lens with a predetermined prescription from a number of lens molds, a gasket, and a source of a fluid material. The apparatus includes a device for selecting a first lens mold and a second lens mold based upon the prescription, a device for positioning the lens molds within the gasket, a device for inserting an amount of the fluid material within the gasket and between the molds, a device for curing the fluid material so as to form the lens, and a device for advancing the lens molds along a predetermined path through the selecting device, the positioning device, the fill device, and the cure device.

Abstract: A high refractive index composition comprising a core resin mixture comprising a first compound of formula (I), a second compound of a poly(ethylene glycol) di(meth)acrylate of formula (II) and a reactive diluent to provide enhanced impact resistance and refractive index.

Abstract: A high refractive index composition comprising a core resin mixture comprising a mixture of ethoxylated bisphenol A di(meth)acrylates and/or their derivatives having variable degrees of ethoxylation to provide enhanced impact resistance and refractive index.
