The present invention is a contact lens treatment solution containing the following copolymer A and copolymer B in a ratio of A/B=40/1 to 5/1 (by weight). According to the present invention, there can be provided a contact lens treatment solution capable of removing dirt having adhered to contact lens surfaces, capable of improving lubricity of contact lens surfaces and capable of imparting persisting hydrophilicity to contact lens surfaces, by simple immersion treatment.

Copolymer A: a copolymer obtained by copolymerization of a monomer (a) represented by formula (1) and a monomer (b) represented by formula (2), in which the copolymerization ratio of the monomer (a) to the monomer (b), a/b=7/3 to 9/1 (by mol), and having a weight-average molecular weight of 400,000 to 800,000.
Copolymer B: a copolymer obtained by copolymerization of a monomer (a) represented by the formula (1) and a monomer (b) represented by the formula (2), in which the copolymerization ratio of the monomer (a) to the monomer (b), a/b=2/1 to 8/1 (by mol), and having a weight-average molecular weight of 1,000,000 to 1,500,000.

A method for disinfecting contact lenses, including immersing the contact lenses in a volume of cleaning agent with about 3% hydrogen peroxide for up to 4 hrs, and immersing up to 0.7 g of a fibrous catalyst enhancer material in the volume of cleaning agent for up to 4 hrs. The fibrous catalyst enhancer material is immersed simultaneously with the contact lenses.

Composition for the removal of biofilms present on a substrate, characterized in that it comprises at least one detergent component comprising a sequestrant and also a wetting agent and a dispersant and at least one enzymatic component containing at least one protease, at least one laccase and at least one polysaccharidase, method of implementation thereof and uses thereof.

Formulations for anti-fogging wipes and/or sprays for transparent and reflective surfaces, such as glasses and/or lenses, along with related methods and kits comprising both wet and dry wipes. In some embodiments, a kit may be provided that may comprise a plurality of dual-compartment packages, each of which may contain a wet wipe container/side having a wet wipe treated with an anti-fogging solution and a separate dry wipe container having a dry wipe for use in removing excess cleaning solution from a lens or other transparent or reflective surface that may be prone to fogging.
