The nursing solution is mainly used to clean and disinfect the lenses. In addition to the daily rubbing and washing of the lenses, the nursing solution in the double box should be replaced every 2-3 days without wearing the lenses. Generally speaking, the nursing liquid needs to be used within three months after opening, but can not be used as eye moistening liquid drops into the eye.
