Abstract: The invention provides a method for producing colored contact lenses with relatively high quality color images. The method of the invention comprises the steps of: obtaining a water based ink having a viscosity of greater than about 100 centipoise (cps) and the ink has a dynamic surface tension of less than about 40 dyne/cm at surface age of about 1 second; applying the ink to a portion of molding surfaces of a lens mold to form a colored coat; actinically curing the ink printed on the mold to form a colored film; dispensing a lens-forming material into the lens-forming cavity of the mold; and actinically or thermally curing the lens-forming material to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens.

Abstract: The present invention provides a method for making colored silicone hydrogel contact lenses.

Abstract: An AC line powered RF transmitter light switch is described. The RF transmitter light switch is installed within a 3-way wall switch circuit thereby allowing direct and constant electrical connection of the RF transmitter light switch and the RF receiving light switch. The RF transmitter light switch is in RF communication with the receiving light switch to control the circuit load or light fixture. The RF receiving light switch is in direct electrical connection to the load and acts as a master controller regarding of the position of the RF transmitter light switch even though the RF transmitter light switch is installed within the 3-way wall switch circuit.

Abstract: The invention is directed to a colored contact lens designed for enhancing a wearer's eye color while giving the wearer's eyes a very natural appearance. A colored contact lens of the invention comprises a colored central zone which includes a colored substantially-circular pattern composed of non-opaque colored dots. Sizes of the dots and/or amounts of space between the dots are varied in a radially-controlled manner so that local colored dot coverage increases in a radial direction from the center to the peripheral edge or a position near the peripheral edge of the substantially-circular pattern.

Abstract: A method comprises the steps of (a) providing a water based ink in at least one cliché with a contact lens pattern; (b) transferring the water based ink from the cliché to at least a surface of at least a contact lens forming mold by means of at least a transfer pad; (c) at least partially curing the ink transferred on the mold to form a colored film; (d) dispensing a hydrogel lens-forming material into a lens-forming cavity of the mold; and (e) curing the lens-forming material within the lens-forming cavity to form the contact lens, whereby the colored film detaches from the molding surface and becomes integral with the body of the contact lens; characterized in that the relative air humidity in the immediate vicinities of the transfer pad/s is kept higher than 50% at standard temperature and pressure conditions during ink transfer.

Abstract: A colored contact lens comprising a non-opaque pupil section, an iris section surrounding the pupil section. A colored, opaque, intermittent pattern is deposited over the iris section using opaque elements which are indiscernible to the ordinary viewer. The elements of the pattern are of a shade which provides a contact lens capable of making subtle changes or enhancements to the color of the iris of a dark-eyed person while imparting a very natural appearance.

Abstract: A color modifying contact lens having an iris pattern having color elements that surround a non-opaque pupil section, wherein the pattern comprises three annular regions: an inner region, an intermediate region, and an outer region. The inner and outer regions each comprise a population of color elements effective to enhance or modify the wearer's eye color as observed by the ordinary viewer. The intermediate region has an area of between about 25-72%, and comprises a population of color elements that covers between about 5-30% of the area within the intermediate region. The color elements in the intermediate region form an array of substantially radial macro-striations that alternate between those having color elements and those without color elements.
