Abstract
A tinted or colored contact lens has a pupil section, an iris section having an area and circumferentially surrounding the pupil section, and a colorant component extending across a major portion of the area of the iris section. The colorant component provides a color to the iris section and at least one additional benefit to the contact lens. For example, the colorant component may enhance the natural appearance of the iris section when the contact lens is in an eye. Alternatively or in addition, the colorant component may enhance the perception of depth in the iris section by an ordinary viewer. Still further, the colorant component may provide a darkened-image within an outer portion of the iris section.
Claims86
A tinted contact lens comprising:
- a pupil section;
- an iris section having an area and circumferentially surrounding the pupil section;
- and
- a colorant component extending across a major portion of the area of the iris section to provide a color to the iris section, the colorant component being configured to provide at least one additional benefit to the contact lens.
A tinted contact lens comprising:
- a pupil section having a periphery;
- an iris section having an area, an outer periphery and circumferentially surrounding the pupil section;
- and
- at least one colored pattern extending across a portion of the area of the iris section to impart to the iris section at least a perception of a structure of an iris of an eye, the at least one colored pattern comprising a plurality of substantially completely colored regions, each of the plurality of regions becoming a series of spaced apart segments near the periphery of the pupil section.
A tinted contact lens comprising:
- a pupil section;
- an iris section having an area and circumferentially surrounding the pupil section;
- a first colorant component positioned to provide a color to at least a portion of the iris section;
- and
- a second colorant component, different from the first colorant component, extending across a major portion of the area of the iris section, the second colorant component being light absorbing and effective to enhance the ability of the contact lens to change a color of an eye wearing the contact lens relative to a substantially identical contact lens without the second colorant component.
A tinted contact lens comprising:
- a pupil section;
- an iris section having an area and circumferentially surrounding the pupil section;
- a colorant component positioned to provide a color to at least a portion of the iris section;
- and
- a substantially optically clear coating covering the colorant component, the coating being effective to provide increased comfort in wearing the tinted contact lens relative to wearing a substantially identical tinted contact lens without the coating.
A tinted contact lens comprising:
- a pupil section;
- an iris section having an area, an outer periphery, and circumferentially surrounding the pupil section;
- and
- a dark colorant configured to provide a darkened-image within an outer portion of the iris section.
A contact lens comprising:
- a pupil section;
- an iris section having an area and circumferentially surrounding the pupil section;
- a substantially optically clear coating covering at least a portion of the iris section;
- and
- an additional substantially optically clear coating covering at least a portion of the iris section and having a different refractive index than the substantially optically clear coating.
A process for making a tinted contact lens having a pupil section, and an iris section having an area and circumferentially surrounding the pupil section, the process comprising providing a colorant component extending across at least a major portion of the area of the iris section to provide a color to the iris section, the colorant component being configured to provide at least one additional benefit to the contact lens.
