Abstract: This invention is directed to a process for applying a symbol (102, 202) to a molded device (101, 201) which symbol on the molded device is visible as an indentation in the surface of the device. The process involves the step of applying the symbol as an elevation to the mold before using the mold for making the molded device. The process of the invention comprises that the elevation on the mold is produced by applying a material to the mold surface which material is liquid when being applied and which material is applied at a temperature higher than the temperature which is at or preferably below the melting point of the material, and which material solidifies at the temperature of the mold. The material applied to the mold and solidified on the mold surface as an elevation needs to remain solid during the process of using the mold for making the molded device. During the molding process the elevation of the symbol on the mold is transferred as an indentation of the symbol to the surface of the molded device. After the molding process is complete and the molded device has been separated from the mold the elevation on the mold surface can be removed and the mold can be re-used without an elevation or with another elevation being applied to make another molded device.
Abstract translation: 本发明涉及一种将符号（102,202）应用于模制装置（101,201）的方法，模制装置上的符号可视为装置表面中的凹陷。 该方法包括在使用模具制造模制装置之前将符号作为高度施加到模具的步骤。 本发明的方法包括通过在模具表面上施加材料来产生模具上的高度，该材料在施加时是液体的，哪种材料在高于或优选低于熔点的温度下施用 的材料，并且哪种材料在模具的温度下固化。 在使用模具制造模制装置的过程中，施加到模具并在模具表面上固化的材料作为高度需要保持固体。 在模制过程中，模具上的符号的高度作为符号的压痕转移到模制装置的表面。 在模制过程完成并且模制装置已经与模具分离之后，可以去除模具表面上的高度，并且可以在没有高度或另外的高度施加模具以重新使用模具以制造另一个模制装置。

Abstract: A method for providing a contact lens for a patient. According to this method, an optical preform (20) is selected, and a resting position of the optical preform on the patient's eye is determined. An optical feature (11) is also located on the patient's eye. Then, a reference position is located on the surface of the optical preform coincident with the optical feature on the patient's eye, when the optical preform is in the resting position. Finally, the optical modification is provided on the optical preform at a location based on the reference position on the optical preform, either by machining the preform itself or by machining a mold that is subsequently used to form the lens.

Abstract: A method and apparatus for producing a plastic lens element having a gradient index of refraction is disclosed in which first and second monomer-containing compositions, each having a different index of refraction, are injected into a centrifugal mold. Precise control of the gradient index is achieved by varying the ratio of the two monomers over a predetermined number of steps during the filling process.
