The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

A method and system for long-term storage of ready-to-eat, minimally processed fruits or vegetables while maintaining the nutritional properties, texture, and taste of fresh fruits or vegetables is provided. The method includes the following steps: providing at least the fruits or vegetables, a sterile sealable package, and a carbonated liquid; treating the fruits or vegetables by at least cleaning and sanitizing the exterior of the fruits or vegetables; placing the treated fruits or vegetables in the sterile sealable package; filling the remaining volume of the sealable package with the carbonated liquid; sealing the sealable package; and storing the sealed package at a storage temperature of 1°C to 40°C. The treating steps are carried out in a sanitized environment.
