5 Frequently Asked Questions About Contact Lens Cases


The proper use of everything related to your contact lenses, including your contact lens case, is essential for good eye health. Your contact lens case’s condition affects both the lenses themselves and your eyes, which is why you need to regularly clean and replace your contact lens case.

Unfortunately, many contact lens wearers are clueless when it comes to the proper way to care for their contact lens cases. Lens.com wants to remedy that. To that end, we answer some of the most common questions people have about contact lens cases in this article.

1. How long can I use my contact lens case?

The lifespan of a contact lens case will vary from person to person. Generally speaking, you should replace your contact lens case every one to three months, even if your current case still looks clean.

2. Why do I need to replace my contact lens case regularly?

It’s important to replace your contact lens case regularly to avoid irritation and infection. Over time, bacteria and other microorganisms can build up on the inside surface of your contact lens case. They can then latch onto your contacts and make it hard for your contact lens cleaning solution to work properly. Wearing contact lenses infested with bacteria and other microorganisms can also cause potentially serious or vision-threatening eye infections.

3. How do I clean my contact lens case?

To avoid any eye-related problems, follow these steps when cleaning your contact lens case:

  1. Wash your hands with mild soap and water. Dry them with a clean, lint-free towel.
  2. Empty your contact lens case, making sure there’s no leftover contact lens solution.
  3. Using a clean, lint-free cloth or a clean finger, scrub the entire interior surface of the contact lens case, including the lids. Spend at least five seconds scrubbing each section of the case to make sure it’s thoroughly clean.
  4. Rinse your contact lens case, including the lids, with several drops of fresh disinfecting solution.
  5. Set your contact lens case face-down on a piece of tissue paper or a clean cloth. Allow it to air-dry.

Remember that you should only use disinfecting solution to clean your contact lens case. Never use other liquids that contain strong chemicals, such as alcohol, bleach, and liquid detergent. These liquids can leave a residue on the interior surface of your contact lens case, and that can stick to your contact lenses, potentially damaging them and putting you at risk for eye infections.

4. Are there any other ways to clean my contact lens case?

An alternative way to clean your contact lens case is to place it in a container of boiling water for a few minutes. This helps to sterilize it. You can do this occasionally, as experts say that rinsing your contact lens case with a disinfecting solution is already sufficient.

5. Can I clean my contact lens case with tap water?

No, you should never clean your contact lens case with water. Tap water is generally safe for drinking but not for cleaning contacts or contact lens cases. Tap water contains germs and contaminants that can stick to your contacts and contact lens case and cause irritation. The same can be said for freshwater, seawater, regular eye drops, saline solution, and even sterilized drinking water.
