A spectacle lens kit comprising a spectacle lens (2, 32, 42, 52) and instructions including a given as-worn position of the spectacle lens (2, 32, 42, 52), wherein the spectacle lens (2, 32, 42, 52) includes - a first zone (4, 34, 44, 54) which, when a spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position, has a focal power that provides a focused image on the fovea, the first zone (4, 34, 44, 54) having a given height (d v) and a given width (d h), and - at least one second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) at least partly surrounding the first zone (4, 34, 44, 54) where the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) contains at least one of the following: (i) a plurality of focusing structures providing a focal power resulting in a myopic defocus when the spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position or (ii) diffusing structures (6, 36, 56) leading to a diffusion of light passing the at least one second zone (5a, 5b, 15, 35a, 35b, 45a, 45b, 55a, 55b); wherein the width (d h) of the first zone (4, 34, 44, 54) is at least four times the height of the first zone (4, 34, 44, 54) and matches the width of the spectacle lens (2, 32, 42, 52), and the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) consists of two sub-zones (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) which are separated from each other by the first zone (4, 34, 44, 54), and which in case (i) each comprise a plurality of focusing structures providing a focal power resulting in a myopic defocus when the spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position, characterized in that the widths of the two sub-zones (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) of the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) match the width of the spectacle lens (2, 32, 42, 52). - a first zone (4, 34, 44, 54) which, when a spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position, has a focal power that provides a focused image on the fovea, the first zone (4, 34, 44, 54) having a given height (d v) and a given width (d h), and - at least one second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) at least partly surrounding the first zone (4, 34, 44, 54) where the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) contains at least one of the following: (i) a plurality of focusing structures providing a focal power resulting in a myopic defocus when the spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position or (ii) diffusing structures (6, 36, 56) leading to a diffusion of light passing the at least one second zone (5a, 5b, 15, 35a, 35b, 45a, 45b, 55a, 55b); wherein the width (d h) of the first zone (4, 34, 44, 54) is at least four times the height of the first zone (4, 34, 44, 54) and matches the width of the spectacle lens (2, 32, 42, 52), and the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) consists of two sub-zones (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) which are separated from each other by the first zone (4, 34, 44, 54), and which in case (i) each comprise a plurality of focusing structures providing a focal power resulting in a myopic defocus when the spectacle lens (2, 32, 42, 52) is positioned according to the as-worn position, characterized in that the widths of the two sub-zones (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) of the second zone (5a, 5b, 35a, 35b, 45a, 45b, 55a, 55b) match the width of the spectacle lens (2, 32, 42, 52).
