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.
Claims32
A method of making a contact lens, comprising:
- (a) obtaining a digitized image of an actual iris of a human eye, the image including a plurality of colors;
- and
- (b) separating the digitized image of the iris into separate colors for reproduction on a multi-colored contact lens having a non-opaque pupil section.
A contact lens, comprising:
- a multi-colored iris simulating design that is obtained from a digitized image of an actual iris of a human eye that has been separated into separate colors of the iris and reproduced on the contact lens to form the multi-colored iris simulating design, the contact lens having a non-opaque pupil section.
A method of making a contact lens, comprising:
- (a) obtaining a digitized image of an iris of an eye comprising a hybrid image of at least two iris images;
- and
- (b) separating the digitized image of the iris into separate colors for reproduction on a contact lens.
A contact lens, comprising:
- a multi-colored iris simulating design that is obtained from a hybrid digitized image of at least two iris images that has been separated into separate colors and reproduced on the contact lens to form the multi-colored iris simulating design.
