Abstract
The present invention provides a lens care kit for disinfecting and/or cleaning contact lenses. The lens care kit of the invention comprising: (1) a lens care solution; (2) a lens case for holding the lens care solution and a contact lens immersed in the lens care solution; (3) a singlet oxygen-generating agent which is dissolved or dispersed in a lens care solution; and (4) a light irradiation source for irradiating the singlet oxygen-generating agent for a period of time sufficient to produce a sufficient amount of singlet oxygen in the lens care solution to disinfect the contact lens.
Claims18
A lens care solution for disinfecting and/or cleaning contact lenses, comprising:
- (1) a singlet oxygen-generating agent which is dissolved or dispersed in a lens care solution;
- and
- (2) one or more components selected from the group consisting of buffering agent(s), lubricant(s), conditioning/wetting agent(s), viscosity-enhancing agent(s), tonicity agent(s), surfactant(s), chelating agent(s), microbicide(s), preservative(s), and combinations thereof.
A method for cleaning and/or disinfecting a contact lens, comprising the steps of:
- (1) bringing one or more contact lenses into contact with a lens care solution contained in a lens case, wherein either or both of the lens care solution and the lens case comprises a singlet oxygen-generating agent, wherein if the lens case comprise the singlet oxygen-generating agent, the singlet oxygen-generating agent is covalently attached onto the solution-contacting surface of the lens case;
- and
- (2) irradiating the singlet oxygen-generating agent for a period of time sufficient to produce a sufficient amount of singlet oxygen in the lens care solution to disinfect the one or more contact lenses.
