Abstract
A spectacle lens, which is manufactured by additive manufacturing, includes interspersing first volume elements and second volume elements. The first and second volume elements are arranged on the grid points of a geometric grid to form a first sub-grid and a second sub-grid, respectively. The first sub-grid forms the first part of the spectacle lens having a dioptric effect for vision for a first object distance and the second sub-grid forms the second part of the spectacle lens having a dioptric effect for vision for a second object distance, which differs from the first object distance.
Claims2
A method for producing a spectacle lens, the method comprising:
- arranging a plurality of first volume elements by additive manufacturing on grid points of a geometric grid to form a first partial grid, the plurality of first volume elements forming a first part of a spectacle lens having a dioptric power for vision at a first object distance;
- arranging a plurality of second volume elements by additive manufacturing on the grid points of the geometric grid to form a second partial grid, the plurality of second volume elements forming a second part of the spectacle lens having the dioptric power for vision at a second object distance that differs from the first object distance;
- and
- interspersing the plurality of first volume elements and the plurality of second volume elements during the additive manufacturing to arrange the first partial grid and the second partial grid penetrating each other, respectively.
