Abstract:
1. A polymer lens comprising: at least a first printed image printed at least one of: on the polymer lens, on a polymer from which the lens is formed and on a mould in which the lens is formed; characterised in that the at least a first printed image is from a digitally encoded image and at least partially formed of a multicolour inkjet image by at least one of a thermal inkjet printer image and a piezo inkjet printer image such that the at least a first printed image forms a chemical bond, self-adhesion bond or polymer-polymer bond with the polymer lens; wherein said at least a first printed image is formed from an ink having viscosity in a range 1 cP to 200 cP and surface tension in a range 20×10-3 N/m (20 dynes/cm) to 70×10-3 N/m (70 dynes/cm).
