Abstract

An optical article includes: an optical substrate, and a functional layer that is light-transmissive and is laminated to the surface of the optical substrate, the period Pk (nm −1 ) of reflectance of the functional layer in the k-space being not more than 3.66×10 −5 .

Claims (24)

1. An optical article comprising:

an optical substrate, and

a functional layer that is light-transmissive and is laminated to the surface of the optical substrate,

the period Pk (nm −1 ) of reflectance of the functional layer in the k-space being not more than 3.66×10 −5 .

2. An optical article according to claim 1 , wherein the period Pk of reflectance of the functional layer is not more than 3.03×10 −5 .

3. An optical article according to claim 2 , wherein the period Pk of reflectance of the functional layer is not more than 2.08×10 −5 .

4. An optical article according to claim 3 , wherein the period Pk of reflectance of the functional layer is not more than 1.59×10 −5 .

5. An optical article according to claim 4 , wherein the period Pk of reflectance of the functional layer is not more than 1.39×10 −5 .

6. An optical article according to claim 1 , wherein the period Pk of reflectance of the functional layer is not less than 2.63×10 −6 .

7. An optical article according to claim 6 , wherein the period Pk of reflectance of the functional layer is not less than 5.26×10 −6 .

8. An optical article according to claim 1 , wherein the functional layer includes a hard coating layer.

9. An optical article according to claim 8 , wherein the functional layer includes a primer layer that is laminated between the hard coating layer and the optical substrate.

10. An optical article according to claim 1 , further comprising an antireflection film laminated on the functional layer.

11. An optical article according to claim 10 , further comprising an antifouling film laminated on the antireflection film.

12. An optical article according to claim 1 , wherein the optical substrate is a plastic lens substrate.

13. An optical article according to claim 12 , wherein the optical article is a spectacle lens.

14. A pair of spectacles comprising:

a spectacle lens according to claim 13 , and

a frame to which the spectacle lens is mounted.

15. A system including an optical article according to claim 1 and for seeing an image through the optical article, the optical article facing the outside.

16. A method for producing of an optical article, comprising:

forming a light-transmissive functional layer on the surface of an optical substrate, the period Pk (nm −1 ) of reflectance of the functional layer in the k-space being not more than 3.66×10 −5 .

17. A method for film formation comprising:

forming a light-transmissive functional layer on the surface of an optical substrate, the period Pk (nm −1 ) of reflectance of the functional layer in the k-space being not more than 3.66×10 −5 .
