An anti-contamination contact lens package includes a substrate and a photocatalyst film layer formed on the substrate. A method for manufacturing the anti-contamination contact lens package is also disclosed.

An antibacterial spectacle part comprises a spectacle part, and a film formed on at least one surface of the spectacle part. The film is formed by a self-polymerization reaction of dopamine, and comprises a plurality of silver nano particles deposited on a surface of the film away from the spectacle part. The disclosure also provides an antibacterial treatment method.

Sterile container (1) comprising a container body (40) having inner surfaces (2, 4) delimiting a containment compartment (6), wherein at least part of said surfaces (2, 4) is made of a compound material comprising a thermoplastic polymer, a first zeolite and a second zeolite homogeneously dispersed in the thermoplastic polymer, each of said zeolites having a micrometric particle size distribution and delimiting reticular voids in which bactericidal and/or bacteriostatic metal ions releasable from said zeolite are housed. The first zeolite comprises silver and copper metal ions, the second zeolite comprises silver and zinc metal ions. The present invention further relates to a sterile product and a compound material.

Contact lens treatment systems and methods for disinfecting contact lenses are described. These systems and methods utilize a coated catalytic disc in combination with a fibrous catalyst. The coated catalytic disc contains a support disc and 6 to 300 mg of manganese present on at least a portion of the support disc, often in the form of manganese dioxide. The fibrous catalyst contains 25 to 50 mg iron, often in the form of an iron cation.

A contact lens composition includes an antibacterial agent and a dispersant. The antibacterial agent is a nanosilver. The dispersant is a polymeric dispersant. When the specific conditions of the percentage of the nanosilver, the percentage of the dispersant and the molecular weight of the dispersant are satisfied, the uniformity of dispersion of the nanosilver can be enhanced.
