Abstract
A flexible, yet self-supporting, optical film processed to include at least one curable resin cured on selected areas thereof. The processed film is useful in a method for simulating one of a multiplicity of opthalmic conditions representative of a disease state or vision disorder. The resin has a surface (or interface with the film) that forms an optically active profile variation in a selected area of the film, that is responsible for refraction or transmission of light, or both, which simulates the one or more opthalmic conditions representative of the disease state. The resin optionally has an opacity variation and optionally has a color variation, each optional variation optionally assisting the film to simulate the one or more opthalmic conditions, such as metamorphopsia.
