Abstract

A spectacle lens design includes an aperture and at least two ring-shaped focusing structures surrounding the aperture. The aperture has a dioptric power, and the ring-shaped focusing structures surrounding the aperture provide an additional power relative to the dioptric power of the aperture. A ring-shaped diffuser is arranged between neighboring ring-shaped focusing structures. Neighboring ring-shaped focusing structures can adjoin each other with a ring-shaped contact line between them forming the ring-shaped diffuser. Neighboring ring-shaped focusing structures can also be arranged at a distance to each other and at least one of the ring-shaped focusing structures provides a ring shaped focal line. Neighboring ring-shaped focusing structures can also be arranged at a distance to each other and at least one of the ring-shaped focusing structures consists of lenslets that adjoin each other so as to form a ring of lenslets and provides a plurality of foci along a ring shaped line.

First claim

The invention claimed is:

1 . A spectacle lens comprising:
an aperture having a dioptric power; and at least two ring-shaped focusing structures surrounding the aperture, the at least two ring-shaped focusing structures providing an additional power relative to the dioptric power of the aperture, the additional power being at least 0.5 dpt., wherein at least one of the at least two ring-shaped focusing structures contains lenslets that adjoin each other to form a ring of lenslets and provides a plurality of foci along a ring shaped line, wherein neighboring ring-shaped focusing structures are formed at a distance from each other, wherein a ring-shaped diffuser is arranged between and contiguously adjoins the neighboring ring-shaped focusing structures, and wherein one of the ring-shaped focusing structures includes the lenslets that adjoin each other to form the ring of lenslets and provides the plurality of foci along the ring shaped line and another one of the ring-shaped focusing structures provides a ring shaped focal line.

2 . The spectacle lens according to claim 1 , wherein the ring-shaped focusing structures are arranged on a back surface of the spectacle lens.

3 . A spectacle lens kit comprising a spectacle lens according to claim 1 and instructions including an as-worn position of the spectacle lens.

4 . A data set stored on a non-transitory computer-readable medium, the data set comprising at least one kind of the following kinds of data:
(i) a representation of the spectacle lens according to claim 1 , configured for a use for manufacturing the spectacle lens; or (ii) data containing computer-readable instructions for controlling one or more manufacturing machines to produce the spectacle lens according to claim 1 .

5 . A data set stored on a non-transitory computer-readable medium, the data set comprising at least one kind of the following kinds of data:
(i) a representation of the spectacle lens kit as claimed in claim 3 , wherein the representation of the spectacle lens is configured for a use for manufacturing the spectacle lens, or (ii) the representation of the spectacle lens kit as claimed in claim 3 , and data containing computer-readable instructions for controlling one or more manufacturing machines to produce the spectacle lens.

6 . A non-transitory computer storage medium comprising at least one kind of the following kinds of data:
(i) a representation of the spectacle lens according to claim 1 configured for a use for manufacturing the spectacle lens; (ii) data containing computer-readable instructions for controlling one or more manufacturing machines in order to produce a spectacle lens according to the spectacle lens according to claim 1 .

7 . A spectacle lens comprising:
an aperture having a dioptric power; and at least two ring-shaped focusing structures surrounding the aperture, the at least two ring-shaped focusing structures providing an additional power relative to the dioptric power of the aperture, the additional power being at least 0.5 dpt., wherein an innermost ring-shaped focusing structure directly adjoins the aperture, wherein a ring-shaped diffuser is arranged between neighboring ring-shaped focusing structures, and wherein the ring-shaped diffuser fills an area between the neighboring ring-shaped focusing structures.

8 . The spectacle lens according to claim 7 , wherein the ring-shaped focusing structures are arranged on a back surface of the spectacle lens.

9 . A spectacle lens comprising:
an aperture having a dioptric power; and at least two ring-shaped focusing structures surrounding the aperture, the at least two ring-shaped focusing structures providing an additional power relative to the dioptric power of the aperture, the additional power being at least 0.5 dpt., wherein the ring-shaped focusing structures each provide a ring shaped focal line, wherein a ring-shaped diffuser is arranged between neighboring ring-shaped focusing structures, wherein neighboring ring-shaped focusing structures adjoin each other with a ring-shaped contact line between the neighboring ring-shaped focusing structures, and wherein the ring-shaped contact line forms the ring-shaped diffuser, wherein a respective cross-section of the at least two ring-shaped focusing structures is identical along a complete ring.

10 . The spectacle lens according to claim 9 , wherein the ring-shaped focusing structures are arranged on a back surface of the spectacle lens.

11 . A computer-implemented method of providing a spectacle lens design for at least retarding myopia progression for the purpose of a use of the design for a manufacture of a spectacle lens, the method comprising:
determining the spectacle lens having a dioptric power; determining at least two ring-shaped focusing structures surrounding the aperture, the at least two ring-shaped focusing structures providing an additional power relative to the dioptric power of the aperture, the additional power being at least 0.5 dpt., determining at least one of the at least two ring-shaped focusing structures to include lenslets that adjoin each other to form a ring of lenslets and to provide a plurality of foci along a ring shaped line; determining the at least two neighboring ring-shaped focusing structures to be located at a distance from each other; determining a ring-shaped diffuser to be located between and to contiguously adjoin the at least two neighboring ring-shaped focusing structures; determining at least one ring-shaped focusing structure of the at least two ring-shaped focusing structures to provide a ring shaped focal line; determining the ring-shaped diffuser to be located between and to contiguously adjoin the neighboring ring-shaped focusing structures, wherein one of the neighboring ring-shaped focusing structures includes the lenslets that adjoin each other so as to form the ring of lenslets and provide the plurality of foci along the ring shaped line and another of the neighboring ring-shaped focusing structures provides the ring shaped focal line.

12 . The computer-implemented method according to claim 11 , further comprising:
determining the ring-shaped focusing structures to be formed on a back surface of the spectacle lens.

13 . The computer-implemented method according to claim 11 , further comprising:
determining the spectacle lens having the dioptric power and determining the at least two ring-shaped focusing structures based on measured eye data.

14 . The computer-implemented method according to claim 11 , further comprising:
manufacturing the spectacle lens based on the determined design.

15 . A computer-implemented method of providing a spectacle lens design for at least retarding myopia progression for the purpose of a use of the design for a manufacture of the spectacle lens, the method comprising:
determining a spectacle lens having an aperture providing a dioptric power; determining at least two ring-shaped focusing structures surrounding the aperture, the at least two ring-shaped focusing structures providing an additional power relative to the dioptric power of the aperture, the additional power being at least 0.5 dpt., determining an innermost ring-shaped focusing structure to directly adjoin the aperture; determining a ring-shaped diffuser to be arranged between the at least two ring-shaped focusing structures; and determining the ring-shaped diffuser to fill an area between the ring-shaped focusing structures.
