Hydrogen peroxide
Multipurpose solutions tend to be less expensive. Contacts do not have to be placed in multipurpose solutions for extended intervals, whereas contacts must be left in a hydrogen peroxide solution for hours. The main attraction of multipurpose solutions is that the same solution can clean, rinse, disinfect and store lenses. Hydrogen peroxide solutions require a separate solution in order to rinse the contacts. Procedural mistakes put eyes at risk from contacting the hydrogen peroxide.
