TINTED CONTACT LENS AND METHOD FOR MAKING SAME
First Claim
1. A method of making a tinted contact lens for insertion into an eye comprising:
- providing a plate having a surface;
lasing the plate to form at least one depression in the surface of the plate, the depression being of a shape constituting an iris portion pattern;
introducing a fluent colorant into the depression;
providing a contact lens substrate;
transferring the colorant from the depression to the lens substrate in a manner so that the colorant colors the lens substrate in a colorant pattern of substantially the same shape as the iris portion pattern of the depression.

Abstract
A tinted contact lens for insertion into an eye comprises a contact lens substrate and an iris-simulating pattern on the lens substrate. The iris simulating pattern comprises at least four distinctly colored colorants. A method for making a tinted contact lens for insertion into an eye comprises providing a plate having a surface, and lasing the plate to form at least one depression in the surface of the plate. The depression is of a shape constituting an iris portion pattern. A fluent colorant is introduced into the depression. The colorant is then transferred from the depression to a lens substrate in a manner so that the colorant colors the lens substrate in a colorant pattern of substantially the same shape as the iris portion pattern of the depression.

10. A method of making a tinted contact lens for insertion into an eye comprising:
-
digitizing an image of a human iris into a computer;
separating the digitized image into a plurality of digitized image portions;
using the plurality of digitized image portions to form a plurality of depressions in a plurality of cliche portions, each depression being of a shape constituting an iris portion pattern;
introducing fluent colorants into the plurality of depressions;
providing a contact lens substrate;
transferring the colorants from the depressions to the lens substrate in a manner so that the colorants color the lens substrate in a plurality of colorant patterns of substantially the same shape as the iris portion patterns of the depressions, the colorant patterns combining with one another to color the lens substrate in a manner to simulate a human iris. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
