Lens comprising at least two optical surfaces (S 1, S 2) each extending transversely relative to an optical axis (A-A) of the lens, so that light rays that pass through the lens pass through one then the other of the two surfaces, each surface comprising active zones (ZA 1, ZA 2) inside of which a shape of said surface is adapted to produce part at least of the optical power of the lens for rays that pass through said active zones, with a sagittal height discontinuity of each surface between two different active zones of said surface, limits of the active zones (ZA 1, ZA 2) of a first of the two surfaces being located in line with limits of the active zones of the other of said two surfaces, said first and second surfaces (S 1, S 2) furthermore comprising separating zones (ZS 1, ZS 2) arranged so that each of the first and second surfaces consists of an alternation between the active zones and the separating zones, each active zone (ZA 1, ZA 2) of one of the first and second surfaces (S 1, S 2) being in line with a separating zone (ZS 2, ZS 1) of the other of said first and second surfaces, and the shape of at least one of the first and second surfaces (S 1, S 2) in at least one of the separating zones (ZS 1, ZS 2) is adapted to increase at least one of the following angles: - a first angle (A 1) formed by said surface (S 1, S 2) in said separating zone (ZS 1, ZS 2) with a direction of a sagittal height jump located at a limit between said separating zone and an active zone (ZA 1, ZA 2) adjacent to said separating zone, - a second angle (A 2) formed by said surface (S 1, S 2) at a limit between said separating zone (ZS 1, ZS 2) and an active zone (ZA 1, ZA 2) adjacent to said separating zone, and - a third angle (A 3) formed by the other surface (S 2, S 1) at a limit of the active zone (ZA 2, ZA 1) of said other surface that is located in line with said separating zone (ZS 1, ZS 2), said third angle being formed by said other surface in said active zone with a direction of a sagittal height jump located at the limit of said active zone, relative to an angle (A 10, A 20, A 30) located at the same location of the lens and formed by an imaginary surface (S 0) obtained by subtracting respective sagittal heights of the first and second surfaces (S 1, S 2), said imaginary surface thus comprising sagittal height jumps located in line with limits between the separating zones and active zones, and the angle (A 10, A 20, A 30) formed by the imaginary surface being measured between said imaginary surface and the sagittal height jump direction, and being acute, the lens being characterized in that a sagittal height variation amplitude of each of the first and second surfaces (S 1, S 2) in at least one of the separating zones (ZS 1, ZS 2) of said surface is smaller than 25% of a sagittal height variation amplitude of the other surface in the active zone (ZA 1, ZA 2) located in line with said separating zone. - a first angle (A 1) formed by said surface (S 1, S 2) in said separating zone (ZS 1, ZS 2) with a direction of a sagittal height jump located at a limit between said separating zone and an active zone (ZA 1, ZA 2) adjacent to said separating zone, - a second angle (A 2) formed by said surface (S 1, S 2) at a limit between said separating zone (ZS 1, ZS 2) and an active zone (ZA 1, ZA 2) adjacent to said separating zone, and - a third angle (A 3) formed by the other surface (S 2, S 1) at a limit of the active zone (ZA 2, ZA 1) of said other surface that is located in line with said separating zone (ZS 1, ZS 2), said third angle being formed by said other surface in said active zone with a direction of a sagittal height jump located at the limit of said active zone,
