1. A spectacle lens comprising:
a first zone of the spectacle lens; and
a second zone of the spectacle lens;
wherein the second zone comprises a plurality of discrete lens segments of the spectacle lens interlaced with the first zone;
wherein the first zone is configured to apply a first refractive optical function to light passing therethrough and the plurality of discrete lens segments of the second zone are configured to apply a second refractive optical function to light passing therethrough, different to the first refractive optical function;
wherein the first refractive optical function comprises a first focal length and the second optical function comprises a second focal length, different to the first focal length;
wherein the first zone occupies a central portion of the lens that is devoid of the plurality of discrete lens segments of the second zone; and
wherein the plurality of discrete lens segments are distributed within a plurality of annular segments of the second zone of the spectacle lens about the central portion of the lens, each annular segment comprising a plurality of the discrete lens segments distributed within it about the central portion of the lens.
