Spectacle lens design, method of manufacturing a spectacle lens and method of providing a spectacle lens for at least retarding myopia progression

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.

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.

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.
