Abstract

Wearable ocular devices (such as ocular prostheses or contact lenses) utilizing diffraction gratings to produce color, as well as methods for producing such devices, are provided. A diffraction grating on the device may diffract the incident light to the observer. The result may be colored light that appears to originate from the wearer'"'"'s eyes. The diffraction grating may achieve a look or feeling that is qualitatively or quantitatively different from the look or feeling achieved by previous devices that use dyes or inks.

Claims

1. A method of imparting a representation to a wearable ocular device, the method comprising:

a. applying an optically absorptive material to a surface of the device;

b. directing a first laser light along a first optical path to the surface of the device;

c. directing a second laser light along a second optical path to the surface of the device; and

d. creating an interference pattern between the first and second laser light at the surface of the device such that the optically absorptive material absorbs light at areas of constructive interference in the interference pattern and ablates nearby portions of the surface of the device, thereby imparting a diffraction grating to the surface of the device.

2. The method of claim 1, wherein the first and second laser light are emitted by a single laser.

3. The method of claim 2, wherein the first and second laser light are directed along the first and second optical paths, respectively, by a spatial filter.

4. The method of claim 3, wherein the first optical path comprises a reference mirror and the second optical path comprises an objective mirror.

5. The method of claim 4, wherein the first laser light is directed from the reference mirror to a first portion of the surface of the device and the second laser light is directed from the objective mirror to a second portion of the surface of the device.

6. The method of claim 5, wherein the first and second portions of the surface of the device partially overlap.

7. The method of claim 1, wherein the representation is an expression or designation.

8. The method of claim 7, wherein the expression or designation is a repository of information about the device.

9. The method of claim 7, wherein the expression or designation is a character or a term.

10. The method of claim 7, wherein the expression or designation is an image.

11. The method of claim 7, wherein the expression or designation is configured to alter an appearance of a wearer of the device for an artistic purpose.

12. The method of claim 7, wherein the expression or designation is a color.

13. The method of claim 1, further comprising repeating (a)-(d) to impart a plurality of diffraction gratings to the surface of the device.

14. The method of claim 13, wherein a first diffraction grating imparts a red hue to the device, a second diffraction grating imparts a green hue to the device, and a third diffraction grating imparts a blue hue to the device.

15. The method of claim 14, further comprising, prior to (a):

(i) selecting a desired color to be imparted to the device, and (ii) determining optical parameters required to produce the first, second, and third diffraction gratings.

16. The method of claim 15, further comprising, prior to (a):

(i) using an optical spectrometer or digital camera to determine a desired color to be imparted to the device, and (ii) determining optical parameters required to produce the first, second, and third diffraction gratings.

17. The method of claim 1, further comprising removing the optically absorptive material from the surface of the device.

18. The method of claim 1, wherein the device is a contact lens or an ocular prosthesis.

19. A method of imparting a representation to a wearable ocular device, the method comprising:

a. selecting a desired representation to be imparted to the device;

b. determining optical parameters required to produce a diffraction grating on a surface of the device that imparts the desired representation to the device;

c. applying an optically absorptive material to the surface of the device; and

d. directing laser light along an optical path through the device to a mirror, such that a first portion of the laser light is reflected from the mirror and creates an interference pattern with a second portion of the laser light at the surface of the device, such that the optically absorptive material absorbs light at areas of constructive interference in the interference pattern and ablates nearby portions of the surface of the device, thereby imparting the diffraction grating to the surface of the device.

20. A method of imparting a representation to a wearable ocular device, the method comprising:

a. applying a phase change material to a surface of the device; and

b. lithographically patterning the phase change material to impart a diffraction grating to the surface of the device.
