Spectacle lens with small higher order aberrations

1. A unifocal spectacle lens having an aspheric or atoric surface, wherein said lens exhibits a small spherical aberration of less than 0.1/mm at a distance r up to 30 mm from the vertex of the lens.

2. A unifocal spectacle lens having an aspheric or atoric surface, wherein said lens exhibits a small coma of less than 0.2/mm at a distance r up to 30 mm from the vertex of the lens.

3. A progressive spectacle lens having higher order aberrations comprising a coma, wherein the ratio of coma and addition is limited such that at an addition of 1, the maximum coma is 0.08; at an addition of 2, the maximum coma is 0.14; and at an addition of 3, the maximum coma is 0.18.

4. A progressive spectacle lens according to claim 3 , wherein the maximum value of the coma is located in a rectangle that is bounded vertically at the top by the centering point and at the bottom by the near reference point, and horizontally on one side by a vertical straight line that goes through the centering point and distance reference point, and on the other side by a vertical straight line that goes through the near reference point of the lens.

5. A progressive lens according to claim 3 , wherein as a function of the pupil diameter, the coma has a smaller gradient at the prism reference point and the near reference point than at the point of maximum coma.

6. A progressive spectacle lens having higher order aberrations comprising a spherical aberration, wherein the ratio of spherical aberration and addition is limited such that at an addition of 1, the spherical aberration is between −0.05 and 0.06; at an addition of 2, the spherical aberration is between −0.13 and 0.11; and at an addition of 3, the spherical aberration is between −0.16 and 0.12.

7. A progressive spectacle lens according to claim 6 , wherein both the maximum value and the minimum value of the spherical aberration are located in a rectangle that is bounded vertically at the top by the centering point and at the bottom by the near reference point, and horizontally on one side by a vertical straight line that goes through the centering point and distance reference point, and on the other side by a vertical straight line that goes through the near reference point.
