Abstract
A method of manufacturing a colored contact lens including the steps of providing a transparent contact lens having a pupil section and an iris section, the iris section surrounding the pupil section and applying a colorant to the surface of the contact lens. The colorant is applied to the contact lens as an amorphous pattern and covers an effective amount of the iris section of the same. The amorphous pattern provides a lens capable of changing the apparent color of the iris of a person wearing the lens while imparting a very natural appearance.

A method of manufacturing a colored contact lens comprising the steps of:
- a) inking, with a color ink, at least one cliché having a transfigured amorphous patterns to be printed on a contact lens to form an inked image in the cliché;
- b) transferring the inked image from the cliché to at least one surface of at least one contact lens forming mold by means of at least one transfer pad,
- (c) at least partially curing the inked image transferred on the mold surface to form a colored film;
- (d) dispensing a hydrogel lens-forming material into at least one 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,
- wherein the transfigured amorphous simulated iris pattern is made by the method comprising the steps of:
- opening or scanning an image file in a photo editing software application, said image file containing an base amorphous image having at least two colors, wherein the amorphous image is totally unrelated to any eye structure;
- distorting the amorphous base image with one or more filters to change the shape of contents of the amorphous base image,
- reducing the opacity of the distorted image to create a translucent image;
- modifying the size of the translucent image to create a sized image;
- and
- cutting out lens shape from the sized image to simulate iris shap, the lens shape being defined by a substantially circular outer diameter having a smaller substantially inner circle removed therefrom.
