An eyeglass lens forming composition containing light absorbing compounds which
may undergo light initiated polymerization is provided. Typically, lens forming
compositions that absorb light do not permit enough activating radiation to penetrate
into the depths of the lens cavity to adequately initiate polymerization of the
lens forming composition. An embodiment of the invention provides a system and
method for curing such a lens forming composition to form a lens that does not
transmit ultraviolet light. Activating light is used having a wavelength greater
than the wavelengths of light which the light absorbing compounds absorb. The power
of the formed lenses may be controlled by varying the lens forming conditions.
Additionally, the lens forming process may be controlled using a microprocessor
based control system.
