Ophthalmic lens with annular optical zones, the individual have a toroidal refracting surface profiles

摘要

The present invention relates to an ophthalmic lens (1) with an optical part (2), the one in the direction of a main optical axis (a) of the eye lens (1) as viewed in the first optical side (4a) and an opposite second optical side (4b), and a plurality of about the main optical axis (a) circumferential, on at least one optical side (4a, 4b), which are annular optical zones (5, 6, 7, 8, 9), a first optical zone (5, 6, 7, 8, 9) a first, a toroidal refractive surface profile (5a, 6a, 7a, 8a, 9a) with at least two zones - main meridian (5b, 5c; 6b, 6c; 7b, 7c; 8b, 8c; 9b, 9c) and at least a second optical zone (5, 6, 7, 8, 9) a second toroidal refractive surface profile (5a, 6a, 7a, 8a, 9a) with at least two zones - main meridian (5b, 5c; 6b, 6c; 7b, 7c; 8b, 8c; 9b, 9c), wherein said at least the first optical zone (5, 6, 7, 8, 9) and the second optical zone (5, 6, 7, 8, 9) in the radial direction of the optical part (2) are in each case limited by the fact that, between a radially inner zones edge (6d) and a radially outer zones edge (6e) of the respective optical zone (5, 6, 7, 8, 9) a zones refractive index value is unchanged and / or the azimuthal axis position of the zones - main meridians (5b, 5c; 6b, 6c; 7b, 7c; 8b, 8c; 9b, 9c) with respect to each other to the respective optical zone (5, 6, 7, 8, 9) is unchanged, and the first optical zone (5, 6, 7, 8, 9) a first zones refractive index value and the second optical zone (5, 6, 7, 8, 9) for a different second zones refractive index value and / or the first optical zone (5, 6, 7, 8, 9) a first azimuthal axial position of the zones - main meridians (5b, 5c; 6b, 6c; 7b, 7c; 8b, 8c; 9b, 9c) and said second optical zone (5, 6, 7, 8, 9) to the first azimuthal position of a different second azimuthal axial position of the zones - main meridians (5b, 5c; 6b, 6c; 7b, 7c; 8b, 8c; 9b, 9c) comprises.
