ABSTRACT:
This invention relates to a contact lens cleaner comprising microcapsules and a desired liquid or semi-solid containing the microcapsules, the microcapsules each being formed by laminating a wall material comprised of an inorganic polishing agent on the surface of a core material having elasticity. The present contact lens cleaner can effectively remove dirt or stain on a contact lens surface without having any adverse effect on the contact lens, and can be very easily removed by washing it away with water after use.
