Abstract

Disclosed is eyeglasses equipment ( 1 ) including a frame ( 10 ), and at least one ophthalmic lens ( 20 ) mounted into the frame. The equipment includes a colored interface ( 30 ) that is placed between the frame and the lens.

First claim

The invention claimed is:

1. Eyeglasses equipment including:
a frame, and
at least one ophthalmic lens mounted into said frame,
wherein said eyeglasses equipment includes an interface that is situated between said frame and said lens and that is colored, and
wherein a face between said lens and said interface has a level of light absorption that is greater than the level of light absorption of a face between said lens and the internal face of said frame.

2. Eyeglasses equipment according to claim 1 , wherein said interface extends at least along a temple part or a nasal part of the periphery of the ophthalmic lens.

3. Eyeglasses equipment according to claim 1 , wherein said interface covers the entire width of the ophthalmic lens.

4. Eyeglasses equipment according to claim 1 , wherein said interface is a thin layer of material distinct from the material of the ophthalmic lens and from the material of the frame.

5. Eyeglasses equipment according to claim 1 , wherein said interface is a joint manufactured by an additive technology, that fastens said frame to said lens.

6. Eyeglasses equipment according to claim 5 , wherein said joint is colored in the mass.

7. Eyeglasses equipment according to claim 5 , wherein said joint is made from a material that is different from the material of the lens and that is also different from the material of the frame.

8. Eyeglasses equipment according to claim 5 , wherein said joint, said frame and said lens form separate pieces.

9. Eyeglasses equipment according to claim 5 , wherein said joint and at least a part of said frame form a single piece.

10. Eyeglasses equipment according to claim 5 , wherein said joint and said lens form a single piece.

11. Eyeglasses equipment according to claim 5 , wherein said joint is formed from an auxetic material.

12. Eyeglasses equipment according to claim 5 , wherein said joint houses at least one electric or electronic component.

13. Eyeglasses equipment according to claim 5 , wherein said joint is formed from an elastic material.

14. Eyeglasses equipment according to claim 13 , wherein said joint comprises a temporal part that has a function of hinge for a temple of said frame.

15. Eyeglasses equipment according to claim 5 , wherein said joint is formed from a rigid material.

16. Eyeglasses equipment according to claim 15 , wherein said joint comprises a temporal part that has a function of attachment for a temple of said frame.

17. Method for providing an eyeglasses equipment including steps of:
selecting a frame, and
selecting at least one ophthalmic lens to be mounted into said frame,
wherein said method includes steps of:
determining a color for an interface, and
assembling said lens and said frame so that said interface is situated between said frame and said lens and so that a face between said lens and said interface has a level of light absorption that is greater than the level of light absorption of a face between said lens and the internal face of said frame.

18. Method according to claim 17 , wherein said interface and said lens are manufactured to form a single piece.

19. Method according to claim 17 , wherein said interface is a joint, including steps of:
acquiring at least one geometrical characteristic of the frame or at least one geometrical characteristic of the lens,
manufacturing said joint by an additive technology, said joint presenting a shape determined as a function of said geometrical characteristics, and
assembling said lens, said joint and said frame, by placing said joint between said frame and said lens.

20. Method according to claim 19 , wherein said joint, said lens and said frame are manufactured from separate pieces.

21. Method according to claim 19 , wherein at least one electrical component is manufactured by additive technology together with said joint, so that said electrical component is housed into said joint.

22. Method according to claim 17 , wherein said interface and at least a part of said frame are manufactured to form a single piece.

23. Method according to claim 22 , wherein said frame is manufactured together with other identical standardized frames.
