Abstract

A system for customization of a photochromic article ( 14 ) includes a container ( 12 ) having an interior ( 28 ). At least one actinic radiation source ( 34 ) is located in the interior ( 28 ) of the container ( 12 ). At least one deactivation radiation source ( 36 ) is located in the interior ( 28 ) of the container ( 12 ). A method of customizing a photochromic article ( 14 ) includes inserting a photochromic article ( 14 ) having at least one non-thermally reversible photochromic material into a container ( 12 ) having at least one actinic radiation source ( 34 ) and actuating the at least one actinic radiation source ( 34 ) to activate the at least one non-thermally reversible photochromic material.

First claim

What is claimed is:

1. A system for customization of a photochromic article, comprising:
a container having an interior;
a holder configured to reversibly secure the photochromic article located in the interior of the container;
at least one actinic radiation source in the interior of the container; and
at least one deactivation radiation source in the interior of the container.

2. The system of claim 1 , wherein the at least one actinic radiation source comprises a plurality of actinic radiation sources.

3. The system of claim 2 , wherein the at least one actinic radiation source comprises an array of actinic radiation sources.

4. The system of claim 1 , wherein the at least one actinic radiation source comprises at least one first actinic radiation source and at least one second actinic radiation source, wherein a wavelength or range of wavelengths of actinic radiation emitted by the at least one first actinic radiation source is different than a wavelength or range of wavelengths of actinic radiation emitted by the at least one second actinic radiation source.

5. The system of claim 1 , wherein the at least one deactivation radiation source comprises a plurality of deactivation radiation sources.

6. The system of claim 5 , wherein the at least one deactivation radiation source comprises an array of deactivation radiation sources.

7. The system of claim 1 , wherein the at least one deactivation radiation source comprises at least one first deactivation radiation source and at least one second deactivation radiation source, wherein a wavelength or range of wavelengths of deactivation radiation emitted by the at least one first deactivation radiation source is different than a wavelength or range of wavelengths of deactivation radiation emitted by the at least one second deactivation radiation source.

8. The system of claim 1 , further including a control device operatively linked to the at least one actinic radiation source and/or the at least one deactivation radiation source, wherein the control device is configured to control at least one of the intensity and duration of the at least one actinic radiation source and/or the at least one deactivation radiation source.

9. The system of claim 1 , further comprising a photochromic article.

10. The system of claim 9 , wherein the photochromic article comprises at least one of a photochromic material and a photochromic-dichroic material.

11. The system of claim 9 , wherein the photochromic article comprises at least one photochromic material comprising at least one non-thermally reversible photochromic material.

12. The system of claim 11 , wherein the at least one photochromic material comprises at least one diaryl ethene compound.

13. The system of claim 9 , wherein the photochromic article comprises a first non-thermally reversible photochromic material and a second non-thermally reversible photochromic material, wherein the first non-thermally reversible photochromic material has a first activation wavelength and the second non-thermally reversible photochromic material has a second activation wavelength.

14. The system of claim 13 , wherein the first activation wavelength is different than the second activation wavelength.

15. The system of claim 9 , wherein the photochromic article comprises a first non-thermally reversible photochromic material and a second non-thermally reversible photochromic material, wherein the first non-thermally reversible photochromic material has a first deactivation wavelength and the second non-thermally reversible photochromic material has a second deactivation wavelength.

16. The system of claim 15 , wherein the photochromic article comprises at least one non-thermally reversible photochromic material and the at least one non-thermally reversible photochromic material is located in a photochromic layer and/or in an optical substrate.

17. The system of claim 15 , wherein the first deactivation wavelength is different than the second deactivation wavelength.

18. The system of claim 9 , wherein the photochromic article is selected from the group consisting of optical articles, ophthalmic articles, display articles, eyewear, visors, windows, and mirrors, preferably eyewear, contact lenses, and clip-on lenses.

19. A method of customizing a photochromic article, comprising the steps of:
inserting a photochromic article comprising at least one non-thermally reversible photochromic material into a container comprising at least one actinic radiation source and securing the photochromic article to a holder configured to reversibly secure the photochromic article located in the interior of the container; and
actuating the at least one actinic radiation source to activate the at least one non-thermally reversible photochromic material.

20. The method of claim 19 , wherein the container further comprises at least one deactivation radiation source and the method includes:
inserting the photochromic article into the container; and
actuating the at least one deactivation radiation source to deactivate the at least one non-thermally reversible photochromic material.
