Abstract

A lens element adapted for a person including a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of the person, a plurality of optical elements placed on at least one surface of the holder to at least one of: slow down, retard, or prevent a progress of the abnormal refraction of an eye of the person, and at least one layer of at least one coating element covering at least a zone of at least one optical element and at least a zone of the holder on which the optical elements are placed, wherein said at least one layer of at least one coating element adds an optical power of 0.1 diopter in absolute value in specific wearing conditions when measured over said zone of the optical element covered by said at least one layer of at least one coating element.

Claims (23)

1. A lens element adapted for a person comprising

a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of the person;

a plurality of optical elements each located on and contacting at least one surface of the holder to at least one of: slow down, retard, or prevent a progress of the abnormal refraction of an eye of the person; and

at least one layer of at least one coating element covering and contacting at least a zone of at least one optical element and covering and contacting at least a zone of the holder on which the optical elements are located,

wherein said at least one layer of at least one coating element adds an optical power of 0.1 diopter in absolute value in a specific wearing condition when measured over said zone of the optical element covered by said at least one layer of at least one coating element.

2. The lens element according to claim 1 , wherein the specific wearing condition corresponds to a standard wearing condition.

3. The lens element of claim 1 , wherein the abnormal refraction of the eye is myopia.

4. The lens element according to claim 1 , wherein for at east one coated optical element, the at least one layer of the at least one coating element is thicker at a periphery of a surface of said coated optical element.

5. The lens element according to claim 1 , wherein for at least one coated optical element, the at least one layer of coating element is thicker at a center of a surface of said coated optical element than at an edge of the surface of said coated optical element.

6. The lens element according to claim 1 , wherein at least a part of the plurality of optical elements are placed in a pattern of at least one ring on the at least one surface at the holder.

7. The lens element according to claim 6 , wherein a mean sphere of each of the coated optical elements placed in the ring pattern is identical.

8. The lens element according to claim 1 , wherein a mean sphere of at least one of the coated optical elements varies from a center to an edge of the coated optical element.

9. The lens element according to claim 1 , wherein at least part of the optical elements are contiguous.

10. The lexis element of claim 2 , wherein the abnormal refraction of the eye is myopia.

11. The lens element according to claim 2 , wherein for at least one coated optical element, the at least one layer of the at least one coating element is thicker at a periphery of a surface of said coated optical element.

12. The lens element according to claim 3 , wherein for at least one coated optical element, the at least one layer of the at least one coating element is thicker in a periphery of a surface of said coated optical element.

13. The lens element according to claim 2 , wherein for at least one coated optical element, the at least one layer of coating element is thicker at a center of a surface of said coated optical element than at an edge of the surface of said coated optical element.

14. The lens element according to claim 3 , wherein for at least one coated optical element, the at least one layer of coating element is thicker at a center of a surface of said coated optical element than at an edge of the surface of said coated optical element.

15. The lens element according to claim 4 , wherein for at least one coated optical element, the at least one layer of coating element is thicker at a center of a surface of said coated optical element than at an edge of the surface of said coated optical element.

16. The lens element according to claim 2 , wherein at least a part of the plurality of optical elements are placed in a pattern of at least one ring on the at least one surface of the holder.

17. The lens element according to claim 3 , wherein at least a part of the plurality of optical elements are placed in a pattern of at least one ring on the at least one surface of the holder.

18. The lens element according to claim 4 , wherein at least a part of the plurality of optical elements are placed in a pattern of at least one ring on the at least one surface of the holder.

19. The lens element according to claim 5 , wherein at least a part of the plurality of optical elements are placed in a pattern of at least one ring on the at least one surface of the holder.
