Abstract
Methods of manufacturing an ophthalmic lens are described. The methods include a step of providing an ophthalmic lens; and a step of providing a photocurable film. The methods use a digital light projections system to photocure at least one region of the film to produce at least one photocured gradient index refractive element. The film is applied to a surface of the lens.
