摘要： 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.

摘要： Method and apparatus for making [and coating] a plastic lens is provided. [Oxygen barrier containing photoinitiator is used to cure incompletely cured lens portions. Radiation pulses are used to control lens curing rate. Lens is postcured while in a mold cavity using a conductive heat source.] More particularly, the invention relates to applying alternating periods of ultraviolet light to lens forming composition. Such composition is cured while controlling the rate of heat generation and/or dissipation via manipulation of the duration of the radiation or the cooling in the curing chamber. The ultraviolet light is directed toward the lens forming composition which is preferably disposed in a mold cavity formed by two mold members. The ultraviolet light may be directed in pulses or continuously.
