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.

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.

摘要： Hard substrates such as ophthalmic lenses or molds are coated with a UV curable monomer which is polymerized to construct a scratch resistant coating on a surface of the lens. The present invention is directed to an apparatus for and method of applying the UV curable monomer to the surface of the ophthalmic lens or mold. Polymerization of the monomer occurs by radiation of UV light while the lens is encased in a curing chamber. The spin coater of the present invention has the following advantages: Excess monomer is collected in a dish away from UV exposure and is readily disposed of. The substrate is revolved at a high rate of speed during the application of the coating to achieve a uniform coating of monomer. Only the holder and substrate are moved to the curing chamber minimizing the items exposed to UV light. The UV light is electrodeless, it has a standby mode and operates cyclically during use so as to prolong its life and to allow a greater degree of control over extent of polymerization. Operation of the apparatus occurs automatically and can be performed by using pneumatic as well as electronic circuits.

摘要： An apparatus for preparing a plastic eyeglass lens includes a coating unit and a lens curing unit. The apparatus is preferably configured to allow the operation of both the coating unit and the lens curing unit. The apparatus may also include a post-cure unit and a controller. The controller is configured to control the operation of the coating unit, the lens curing unit and the post-cure unit. The lens forming unit may include an LCD filter disposed between activating light sources and a mold assembly. The mold assembly preferably includes two mold members held together by a gasket. The gasket preferably includes four protrusions spaced at 90 degree intervals about the gasket. A lens forming composition may include a first photochromic compound, a second photochromic compound and a light effector. The light effector may alter the color of a lens when exposed to photochromic activating light, when compared to a lens formed from a lens forming composition which does not include a light effector.
