Abstract: 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.

Abstract: A gel composition comprises hydrophilic monomers, a cross-linking agent, an initiator, and astaxanthin-modified cyclodextrin complexes. The astaxanthin-modified cyclodextrin complexes comprise astaxanthin and modified cyclodextrin. The modified cyclodextrin has a chemical structure of with a hollow cavity, wherein R represents a chemical group having carbon-carbon double bond. The astaxanthin is embedded in the hollow cavity. The disclosure also provides a method for manufacturing a gel composition, and a method for manufacturing an ophthalmic lens using the gel composition.

Abstract: A method for sterilizing an ophthalmic lens with long-term inhibition against regrowth of micro-organisms includes the step of placing the ophthalmic lens in a sealed container containing a care solution. A photocatalytic agent coated in an inner surface of the container is exposed to ultraviolet light, to cause the photocatalytic agent to undergo a photocatalytic reaction under the ultraviolet light, which causes destruction of micro-organisms on the ophthalmic lens.
