| The present invention provides a method of modifying a lens, for example an ophthalmic lens. The method comprises providing an optically transparent lens comprising an organic polymer composition containing a photochemically active dye. The optically transparent lens is irradiated with light having a wavelength and an intensity sufficient to transform at least a portion of the photochemically active dye into a photoproduct or photoproducts within the irradiated volume elements of the optically transparent lens to produce refractive index variations in a modified optically transparent lens. In certain embodiments, the modified optically transparent lens is subjected to a stabilization step to provide a light stable modified optically transparent lens. Stabilization is required only when the starting photochemically active dye and/or the photoproduct(s) are unstable under ambient conditions. | ||||||
