Abstract
Contact lenses and methods of manufacture are provided. In one aspect, a method includes: positioning components in predefined locations on a first surface; applying pressure on the components employing a second surface; providing molten material between the first surface and the second surface and around the components; embedding the components in a substrate by cooling the molten material and causing the molten material to harden, the substrate being a substantially solid form of molten material; and removing the first surface and the second surface after embedding the components in the substrate. The method can also include: providing, on or within a contact lens, one of the components and the substrate into which the component is embedded. The first surface can include molds sized to receive and maintain the components at the predefined locations. The first surface and/or the second surface can be pre-treated with a non-stick coating such as Polytetrafluoroethylene.
