A method of simultaneously cleaning and disinfecting a contact lens is disclosed, which method comprises the steps of: (a) preparing a cleaning solution for the contact lens comprising an effective amount of a proteolytic enzyme, 15-60w/v% (percent by weight/volume) of propylene glycol, 10-60w/v% of glycerine, and water, a total content of the propylene glycol and glycerine being in a range of 30-80w/v%; (b) diluting the cleaning solution with a disinfecting or storing liquid for the contact lens which contains an ionic antimicrobial agent, so as to provide a dilution; and (c) immersing the contact lens in the dilution. |
