Abstract: Laser radiation can be directed through an aperture to a target surface without causing the expected diffraction groove effect by moving the target relative to the stage to which the aperture is attached in such a fashion as to interrupt the diffraction pattern and minimize the production of diffraction grooves.

Abstract: Surface characteristics of cast molded contact lenses are improved by removing substantially all the oxygen from the plastic mold pieces prior to casting the lenses.

Abstract: Urea- and urethane-containing monomers for contact lens materials are disclosed.

Abstract: Urea- and urethane-containing monomers for contact lens materials are disclosed.

Abstract: Temples for eyewear include a first portion for contacting the head of the wearer and a second portion for connecting the first temple portion to the eyewear front. The first temple portion is movable to accommodate a wide variety of head shapes or sizes and provide a more secure fit.

Abstract: An improved method for forming plastic molds for casting articles having an optical surface such as contact lenses employs a plastic tool having an optically smooth surface.
