摘要： A spectacle lens design for a spectacle lens (2) to be positioned relative to the eye of a wearer according to a given as-worn position is provided. The spectacle lens design includes
- a clear distance zone (4),
- a clear near zone (5), and
- an intermediate zone (6) located between the clear distance zone (4) and the clear near zone (5) such that, when a spectacle lens (2) manufactured according to the spectacle lens design is positioned according to the as-worn position, the line of sight moves through the intermediate zone (6) when the viewing direction changes from viewing through clear distance zone (4) to viewing through the clear near zone (5) or vice versa. This intermediate zone (6) includes at least one of the following: focusing structures providing a focal power resulting in a myopic defocus when a spectacle lens (2) manufactured according to the spectacle lens design is positioned according to the as-worn position or diffusing structures (6a) leading to a diffusion of light passing the intermediate zone (6) According to the invention, at least one of the clear distance zone (4) and the clear near zone (5) extends over the whole width of the spectacle lens design.
In addition, a computer-implemented method of designing a spectacle lens and method of manufacturing a spectacle lens are provided

摘要： This computer-implemented method for providing a finished single vision ophthalmic lens intended for a wearer, from a target lens having at least one complex surface, the finished lens having a rotationally symmetrical front surface, comprises: (a) providing wearer data or theoretical data; (b) defining targeted optical or geometrical characteristics along a predetermined path on the target lens, based on the wearer data or on the theoretical data; (c) determining the finished lens by: (c1) selecting an initial lens complying with the prescription data and having a rotationally symmetrical front surface and a predetermined curvature at a prescription reference point; (c2) defining a current lens as the initial lens; (c3) modifying a front surface definition of the current lens to reach the targeted optical or geometrical characteristics until an ending criterion is met; (d) providing the finished lens as the current lens.

摘要： A computer implemented method of determining a numerical representation of a spectacle lens is provided. In the method, a numerically represented working spectacle lens (17) is optimized by means of ray tracing using a number of pencils of rays (27, 29) along different viewing directions of an eye in order to obtain an optimized working spectacle lens which constitutes the numerical representation of the spectacle lens to be determined. The principal rays (35, 37) of the pencils of rays (27, 29) each pass different ray passing points (31, 33) forming points of a vertex surface (19, 119) and wherein the principal rays (35, 37) of the pencils of rays (27, 29) extend along a viewing direction related to the respective ray passing point (31, 33). The three-dimensional locations of the ray passing points (31, 33) are determined by surface points of a non-spherical apex surface (11) representing the locations of the apex (5) of the cornea (3) when the eye (1) rotates, and a fixed distance (vd) which is added to the apex surface (11) at the respective surface points in a direction that corresponds to the viewing direction of the eye (1) when the apex (5) of the cornea (3) is located at said surface point.
