Follow your care system
Use the solution recommended for your lenses and follow its instructions. Do not top up old solution with fresh solution. Hydrogen peroxide systems need their specified neutralisation process before lenses go back into your eyes.
Remember the case
CDC recommends rubbing and rinsing the case with fresh solution, then emptying and drying it. Ask your practitioner when to replace the case and how your lens replacement schedule differs from the cleaning schedule.
