While we know that cleaning contact lenses is a crucial part of lens care, properly cleaning contact lens cases is just as important. Cleaning your case is simple and requires minimal preparation.

Ready to get started? Learn how to clean a contact lens case by following these easy steps:

  1. Wash your hands – Thoroughly clean your hands with soap and water before handling your contact lens case. This will help prevent the spread of bacteria.
  2. Dry your hands – Use a clean, lint-free towel to completely dry your hands after washing them.
  3. Empty the solution – Pour out the old solution from your contact lens case and discard it down the drain.
  4. Rinse the case – Rinse your contact lens case with fresh solution to remove any remaining debris or solution.
  5. Air dry the case – Shake out any excess solution and let your contact lens case air dry completely. The best way to do this is to place the case face down on a clean tissue. Avoid using a hair dryer or other heat source to dry it.

Important rules of cleaning the contact lens case

  • Do not use tap water to clean your contact lens case. Tap water can contain bacteria and protozoa that can lead to serious eye infections such as Acanthamoeba keratitis.
  • Do not use soap or other cleaning agents to clean your case. These products can damage the case and make it more difficult to clean.
  • Do not store your contact lens case in a humid environment. Moisture can encourage the growth of bacteria.
  • Do not boil contact lens case.
  • Do not put the contact lens case in the dishwasher.
  • Do not use alcohol to clean contact lens case.
You may see some information online that suggests boiling contact lens cases in water or putting cases in a dishwasher. Water can introduce harmful bacteria to cases and lenses, increasing the risk of serious infection. To keep your eyes safe, never use water to clean a lens case, even if the water is boiled.
