Quick Answer
To clean your contact lens case properly, empty it, rub the inside with fresh contact lens solution, rinse thoroughly, and let it air dry upside down on a clean tissue. Repeat this routine daily and replace your case every three months to prevent bacterial buildup.
Your contact lens case is a breeding ground for bacteria if not cleaned correctly. Even if you always wash your hands before handling lenses, a dirty case can undo your efforts and lead to eye infections. Fortunately, keeping your case clean is simple when you follow a consistent routine.
This guide walks you through the proper steps to clean and disinfect your contact lens case, highlights common mistakes to avoid, and explains how to extend the life of your case while protecting your eyes.
Why Cleaning Your Contact Lens Case Matters
Contact lens cases accumulate protein deposits, bacteria, and fungi over time. If not cleaned regularly, these contaminants can transfer to your lenses and cause discomfort, redness, or serious infections like keratitis. Studies show that a significant percentage of eye infections are linked to poor lens case hygiene.
Even if you use daily disposable lenses, you still need a case for those occasional times you remove lenses early. For monthly or yearly lenses, the case is your primary defense against contamination. A few minutes of care each day can save you from painful eye issues.
What You'll Need
To clean your case properly, you only need a few items: fresh contact lens solution (never water or saline), clean hands, and a dry, lint-free cloth or tissue. Avoid using tap water, as it contains microorganisms that can cause severe eye infections.
You should also have a backup case on hand. Rotating between two cases allows each to dry completely between uses, reducing bacterial growth. Replace your case at least every three months, or immediately after an eye infection.
Step-by-Step Cleaning Routine
- Empty and Rinse: Remove the lenses and discard the old solution. Rinse each well of the case with fresh contact lens solution. Do not use water. Checkpoint: Ensure no old solution remains, as it may harbor bacteria.
- Rub the Inside: Apply a few drops of solution to each well and gently rub the inside with a clean finger for about 10 seconds. This loosens protein deposits and biofilm. Common mistake: Skipping this step leaves residue that can irritate eyes.
- Rinse Again: Rinse the wells and the case lid thoroughly with fresh solution to remove loosened debris. Checkpoint: Make sure no visible debris remains.
- Air Dry Upside Down: Place the case and lid upside down on a clean tissue or lint-free cloth. Let them air dry completely. Do not seal the case while wet. Common mistake: Closing the case damp encourages mold growth.
- Store Properly: Once dry, reassemble the case and store it in a clean, dry place. Do not expose it to direct sunlight or humidity. Checkpoint: Keep the case away from bathroom moisture.
