  • Publication number: 20120091368
    Abstract: A method and kit for producing reversibly dyed soft contact lenses. The contact lenses are submerged in saline solution and a dye is added to the saline solution, either directly or by means of a strip that has been impregnated with the dye. Preferred dyes include the common dyes sodium fluorescein, lissamine green, and rose bengal. After a period of time, the lens absorbs the dye and can be removed from the solution and placed on the eye. Once the lens is illuminated with ultraviolet light, it will glow or fluoresce. This creates a dramatic effect, particularly in dimly lit areas. The dyeing method does not utilize heat and thus is reversible. Soaking the lens in additional saline solution for a period of time will cause the dye to return to its non-dyed state.

These additives include moisture getters, thermally-activated organic/inorganic hybrids, radical scavengers, antioxidants, UV stabilizers, and photoretarders. For water and oxygen scavengers, activation at elevated temperatures or through another activation method is preferred. This allows for the handling of the device materials containing the scavenger under a lower temperature condition in air where higher levels of ambiently-supplied water or oxygen may also be present. The invention also improves operational lifetimes as getters, scavengers and similar acting additives serve to reduce detrimental reactive species that transport into the device, are generated during operation, or become reactive during operation due to the presence of excited states or external stimulation by electrical, optical or other means.
