Why Cleaning Contact Lenses Properly Matters
Cleaning contact lenses removes debris, natural eye oils, protein deposits, and microorganisms that accumulate during everyday wear. A consistent cleaning routine helps maintain comfort, clearer vision, and safer long-term use of reusable lenses.

How dirt, protein deposits, and bacteria build up on contact lenses
Throughout the day, your contact lenses collect proteins from tears, environmental dust, cosmetics, skin oils, and bacteria transferred during handling. Even lenses that appear clean can develop microscopic deposits that reduce comfort and clarity if not removed regularly.
Risks of wearing poorly cleaned contact lenses
Skipping cleaning steps, reusing old solution, or storing lenses incorrectly may increase the risk of irritation, blurry vision, unpleasant odors, and contamination. Proper cleaning and disinfecting help protect both your eyes and the lifespan of reusable contact lenses.
Before You Start: Contact Lens Cleaning Safety Checklist
Preparing properly before handling your lenses greatly reduces the chance of contamination.
- Wash your hands thoroughly with soap and water.
- Dry hands using a clean, lint-free towel.
- Use only fresh contact lens solution recommended for your lenses.
- Ensure your contact lens case is clean and ready for storage.
- Work on a clean, dry surface with good lighting.
Wash and dry your hands correctly
Clean hands are one of the most important parts of contact lens hygiene. Oils, lotions, and bacteria on your fingers can easily transfer onto the lens surface.
Use the right contact lens solution
Never substitute contact lens solution with water, saline intended only for rinsing, homemade mixtures, or household disinfectants. Always use products specifically formulated for cleaning and disinfecting your type of contact lenses.
Prepare a clean lens case and workspace
Before removing your lenses, confirm your case has been cleaned and allowed to dry properly. Replace old solution with fresh solution every time you store your lenses.
How to Clean Contact Lenses Properly (Step-by-Step)
-
Remove your lenses safely
Wash your hands first, then gently remove one lens at a time to avoid mixing them up or accidentally tearing them.
-
Rub and rinse the lenses with solution
Place one lens in your palm, apply several drops of fresh multipurpose solution, and gently rub both sides with a clean fingertip before rinsing thoroughly.
-
Disinfect the lenses before storage
Place the cleaned lenses into a disinfected case filled with fresh solution. Allow them to soak for the time recommended on your solution's instructions.
-
Store lenses correctly overnight
Keep lenses completely submerged in fresh solution inside a clean case until you are ready to wear them again.
Quick tip: Never rinse or store contact lenses in tap water. Water can contain microorganisms that are unsafe for contact lens use.
How to Clean Different Types of Contact Lenses
Cleaning soft contact lenses
Soft contact lenses require gentle handling because they absorb moisture and deposits more easily. Follow your manufacturer's recommended cleaning and replacement schedule.

Cleaning rigid gas permeable (RGP) lenses
Rigid gas permeable lenses often require specialized cleaning products. Always use products approved for RGP lenses and follow your eye-care provider's instructions.
Cleaning daily disposable lenses
Daily disposable contact lenses are designed for single-day use only. They should not be cleaned, stored, or reused after removal.
How to Clean and Replace Your Contact Lens Case
Your contact lens case can become contaminated if it is not cleaned regularly. Empty old solution after every use, rinse the case with fresh contact lens solution if recommended by the manufacturer, and allow it to air dry upside down on a clean tissue.
How often should you replace a contact lens case?
Most eye-care professionals recommend replacing reusable contact lens cases every one to three months, or sooner if the case becomes cracked, discolored, or difficult to clean.
Best Contact Lens Cleaning Tips for Daily Use
- Always use fresh contact lens solution.
- Never "top off" yesterday's solution with new solution.
- Store lenses only in a clean case.
- Keep your hands clean before touching lenses.
- Replace lenses according to their prescribed schedule.
How to avoid contamination during lens cleaning
Touch only one lens at a time, avoid placing lenses on bathroom counters, and close solution bottles immediately after use.
Common habits that damage contact lenses
| Mistake | Why it happens | Safer alternative |
|---|---|---|
| Using tap water | Seems convenient | Use fresh contact lens solution only |
| Reusing old solution | Trying to save solution | Discard old solution every time |
| Skipping rubbing | Assuming soaking is enough | Rub and rinse unless instructed otherwise |
| Keeping an old case too long | Easy to forget | Replace every 1–3 months |
| Overwearing lenses | Ignoring replacement schedule | Replace lenses on time |
Gentle cleaning helps preserve lens comfort and clarity.
What Not to Do When Cleaning Contact Lenses
- Do not clean lenses with tap water.
- Do not use saliva.
- Do not reuse old contact lens solution.
- Do not store lenses dry.
- Do not wear damaged or uncomfortable lenses.
Why you should never use tap water or saliva
Neither tap water nor saliva is sterile. They may introduce microorganisms that increase the risk of eye irritation or infection.
Why expired or homemade solutions are unsafe
Expired or homemade cleaning solutions cannot reliably disinfect contact lenses. Always use fresh, manufacturer-approved products.
Can You Clean Contact Lenses With These Methods?
Does contact solution clean contacts?
Yes. Approved multipurpose solutions help clean, rinse, disinfect, and store reusable contact lenses when used exactly as directed. For many reusable lenses, gently rubbing before soaking improves cleaning performance.
Can you clean contacts with alcohol?
No. Alcohol should never be used directly on contact lenses because it can damage the lens material and irritate your eyes. While some people use isopropyl alcohol to disinfect the outside of an empty lens case, it must never come into contact with the lenses themselves and the case must dry completely before reuse.
When to Stop Wearing Contact Lenses and Seek Eye Care
Remove your contact lenses immediately and seek professional eye care if you develop significant discomfort, redness, persistent blurry vision, unusual discharge, or increasing sensitivity to light.
Signs your lenses may be contaminated or damaged
- Persistent discomfort
- Redness that does not improve
- Blurred vision
- Visible tears or scratches on the lens
- Cloudy deposits that remain after cleaning
