The present invention provides a metal oxide dispersion comprises a metal oxide, a millbase and a dispersant. The dispersant in the metal oxide is selected from a group consisting of a phosphoric acid polyester copolymer, a trimethoxysilane compound, a triethoxysilanes compound, dimethylamino ethyl methacrylate (DMAEMA) and a combination thereof, and the dispersion is substantially free of water. The metal oxide dispersion of the invention is useful for manufacturing an inkjet ink to provide a high-quality color image on a contact lens or a mold so as to produce a colored contact lens.

Processing a set of images is disclosed, including: determining a set of user head measurements from a set of images; and determining a fit score corresponding to a glasses frames based at least in part on comparing the set of user head measurements to glasses frame measurements associated with the glasses frames.

A method for retarding the progression of myopia in a human eye, the method comprising: providing (41) a concentric annular multi-zone refractive lens including: at least one correcting zone of optical power for correcting (42) refractive error, and at least one defocusing zone for projecting (43) at least one non-homogenous defocused image in front of at least a part of retina to inhibit myopic eye growth, the at least one defocusing zone having at least one less negative power; wherein the correcting and defocusing zones are alternated (45) in the lens and the zones are connected (46) to each other through integrated progressive transition curves.
