A contact lens container can include a body. The body can include a floor, at least one wall connected to the floor, a cavity defined, at least in part, by the floor and the at least one wall, and a sensor oriented to take a measurement of a contact lens solution within the cavity when the cavity is at least partially filled with a contact lens solution.

The present invention is generally directed to a hydrogen peroxide-based lens care system for disinfecting contact lenses. Unlike hydrogen peroxide-based system known in the prior art, a lens care system of the present invention involves electrochemically neutralizing of hydrogen peroxide after any desired period of disinfection time for which contact lenses have been immersed in a hydrogen peroxide-based lens care solution.

The invention provides contact lens storage, cleaning and treatment compositions comprising nonionic surfactants. The invention further provides methods for treating enhancing contact lens wear time and comfort, reducing contact lens deposits and treating dry eye via contact lenses.

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.

The invention is directed to a method of cleaning and disinfecting a contact lens. The method includes instructing a consumer to disinfect their contact lens comprising the following steps: remove a contact from an eye and position the lens in a lens assembly that includes a cap member; add a disinfection solution to the lens case such that the lens is submerged in the solution upon closure of the lens case with the cap member. The disinfection solution will comprise 0.5 wt. % to 6 wt. % hydrogen peroxide or a chemical precursor of hydrogen peroxide, and a P-metal modulating compound. The presence of the P-metal modulating compound in the disinfection solution decreases the neutralization rate of the hydrogen peroxide. The disinfection system exhibits a pseudo first-order, half-life of hydrogen peroxide from 12 minutes to 30 minutes over an initial sixty minutes of neutralization following exposure of the disinfection solution to a catalyst comprising a P-metal. This reduction in rate of peroxide neutralization can provide a more effective solution for killing certain microorganisms and fungi.

A method of sterilizing a preform includes steps of: sterilizing bacteria adhering to a preform (1) made of resin by gasifying a sterilizer, discharging a sterilized gas (G) from a nozzle (6) toward a preform (1), now traveling, so as to adhere to the preform (1); activating the sterilizer adhering to the preform (1) by blasting hot air (P) to the preform; and sterilizing bacteria adhering to the preform, and removing the sterilizer adhering to the preform (1), wherein the above steps are performed sequentially in order. According to the above-mentioned steps, the sterilizer does not enter a blow-molding machine.

An anti-microbial preservative for use in ophthalmic and dermatologic products. The preservative includes from about 0.005 wt. % to about 0.20 wt. % chlorite compound and from about 0.005 wt. % to about 0.05 wt. % peroxy compound. Additionally, the preservative does not generate chlorine dioxide within the pH range of 5.0-8.8. Also included are an antimicrobial ophthalmic and dermatologic compositions for direct application onto an eye or skin of a living being including from about 0.005 wt. % to about 0.20 wt. % chlorite compound and from about 0.005 wt. % to about 0.05 wt. % peroxy compound. Also included are methods for treating dryness of the eyes and skin disorders (e.g., wounds, burns, infections, ulcerations, psoriasis, etc.) and for disinfecting and cleansing contact lenses while in place upon an eye by applying the composition to the eye or to the contact lens.
