Described herein is a cost-effective and time-efficient method for producing photochromic contact lenses, in particular, preferably photochromic silicone hydrogel contact lenses, from a polymerizable composition comprising an unique selection and combination of main polymerizable components, a photochromic compound and a visible-light photoinitiator, based on the Lightstream Technology?. This invention also provides photochromic contact lenses or more preferably photochromic silicone hydrogel contact lenses made according to a method of the invention. A photochromic contact lens of the invention is capable of undergoing a reversible color change upon exposure to UV-irradiation or high-energy-violet light (HEVL) (with wavelengths from 380 nm to 440 nm).

A method of drawing a material into sheet form includes forming a preform comprising at least one material as a large aspect ratio block wherein a first transverse dimension of the preform is much greater than a second transverse dimension substantially perpendicular to the first transverse dimension. A furnace having substantially linearly opposed heating elements one spaced from the other is provided and the heating elements are energized to apply heat to the preform to create a negative thermal gradient from an exterior surface along the first transverse dimension of the preform inward toward a central plane of the preform. The preform is drawn in such a manner that the material substantially maintains its first transverse dimension and deforms across its second transverse dimension.
