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.

The present invention relates to a lens care solution having 0.001 to about 5 weight percent of a low molecular weight amine of the general formula: ##STR00001## where R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are H or low molecular weight radicals, and R.sub.5 is a low molecular weight radical, or salt thereof; an effective amount of a tonicity agent; and the balance water.

A storage solution for an ophthalmic lens comprises an osmotic pressure adjusting agent, sodium chloride, and deionized water. The osmotic pressure adjusting agent is selected from a group consisting of betaine, L-carnitine, and erythritol, or any combination thereof. The storage solution has an osmotic pressure of about 280 mOsm/kg to about 320 mOsm/kg. The disclosure also provides an ophthalmic product using the storage solution.

A packaging system for the storage of an ophthalmic device is disclosed. The packaging system comprises a sealed container containing one or more unused ophthalmic devices immersed in an aqueous packaging solution comprising (a) one or more osmoprotectants, (b) one or more poloxamer comfort agents and (c) one or more polyol demulcents, wherein the aqueous packaging solution has an osmolality of at least about 150 mOsm/kg, a pH of about 6 to about 9 and is heat sterilized.

Provided is a soft contact lens solution that imparts surface hydrophilicity, lubricity, and a lipid adhesion-suppressing ability to a soft contact lens. It has been found that a solution containing two specific kinds of copolymers and a buffering agent can achieve the above-mentioned object. Thus, the soft contact lens solution of the present disclosure has been completed.

The present invention relates to improved ophthalmic solutions that employ select B vitamins; pyridoxine and its salts; and thiamine and its salts in order to more effectively preserve solutions and to reduce the degree to which cationic preservatives will deposit on contact lenses. Ophthalmic solutions are here understood to include contact lens treatment solutions, such as cleaners, soaking solutions, conditioning solutions and lens storage solutions, as well as wetting solutions and in-eye solutions for treatment of eye conditions.

The invention relates to a porous hydrogel matrix having substantially interconnected tunnel-shaped micropores with a three-dimensional configuration of an interconnected hollow tetrapod network. Such matrices may be used to entrap motile cells that migrate into the micropores of said matrix. The matrices of the invention are formed by a method comprising the steps of providing a solution of a hydrogel-forming material, providing a template material with a three-dimensional configuration corresponding to the negative configuration of the desired interconnected porous structure of the hydrogel material, said template material comprising interconnected zinc oxide tetrapod (t-ZnO) networks, casting the solution of hydrogel-forming material onto the template and removing the template material from the hydrogel material by acid hydrolysis of the template material.
