Do You Know the Proper Way to Clean Contact Lenses?

 


Wearing contact lenses is a convenient and effective way to correct vision, but improper cleaning and maintenance can lead to serious eye infections and discomfort. Many contact lens wearers unknowingly adopt poor hygiene habits that put their eye health at risk. In this comprehensive guide, we’ll cover the proper way to clean contact lenses, common mistakes to avoid, and best practices for maintaining healthy eyes.

Why Proper Contact Lens Cleaning is Essential

Contact lenses sit directly on the cornea, making them a potential breeding ground for bacteria, fungi, and other microorganisms. Failure to clean and store them correctly can result in:

  • Eye infections such as keratitis (corneal inflammation)

  • Redness, irritation, and discomfort

  • Protein and debris buildup that affects vision clarity

  • Increased risk of corneal ulcers and long-term eye damage

Step-by-Step Guide to Cleaning Contact Lenses

1. Wash and Dry Your Hands Thoroughly

Before handling your contact lenses, always wash your hands with mild, fragrance-free soap and dry them with a lint-free towel. Avoid using moisturized or scented soaps, as they can leave residue on the lenses.

2. Use the Correct Contact Lens Solution

Never use tap water, saliva, or homemade saline solutions to clean your lenses. Always use a doctor-recommended multipurpose solution or a hydrogen peroxide-based cleaner, depending on your lens type.

3. Rub and Rinse the Lenses

Even if your solution is labeled “no-rub,” it is still best to rub your lenses gently to remove deposits and bacteria. Follow these steps:

  • Place one lens in the palm of your clean hand.

  • Apply a few drops of solution and use your fingertip to rub the lens in a circular motion for about 10-15 seconds.

  • Rinse the lens thoroughly with fresh solution.

  • Repeat for the other lens.

4. Store Lenses in a Clean Case

  • Fill the lens case with fresh solution each time (never reuse old solution).

  • Place each lens in its designated compartment.

  • Close the case securely and let the lenses soak for the recommended time (usually at least 6 hours for disinfection).

Common Contact Lens Cleaning Mistakes to Avoid

1. Topping Off Old Solution

Many people make the mistake of adding new solution to old solution in their lens case. This dilutes the disinfecting properties, allowing bacteria to thrive. Always discard old solution and use fresh solution every time.

2. Using Tap Water or Saliva

Tap water contains harmful microbes that can lead to serious infections like Acanthamoeba keratitis, which can cause permanent vision loss. Saliva also contains bacteria and should never be used as a substitute for cleaning solution.

3. Failing to Clean the Lens Case

Your lens case should be cleaned and dried daily to prevent bacterial buildup.

  • Empty the case completely after each use.

  • Rinse it with fresh lens solution (not tap water!).

  • Let it air dry upside down on a clean tissue.

  • Replace the case every 1-3 months to avoid contamination.

4. Sleeping with Contact Lenses In

Unless prescribed for extended wear, sleeping in contact lenses significantly increases the risk of infection. Overnight wear reduces oxygen supply to the cornea, leading to dryness and inflammation.

How Often Should You Replace Your Contact Lenses?

Contact lenses have different replacement schedules depending on their type:

  • Daily disposable lenses: Discard after one use.

  • Biweekly lenses: Replace every 14 days.

  • Monthly lenses: Replace every 30 days.

  • Rigid gas permeable (RGP) lenses: Can last 1-2 years with proper care but require regular deep cleaning.

Following the manufacturer’s replacement schedule is essential to prevent eye infections and discomfort.

Additional Tips for Contact Lens Wearers

  • Avoid wearing lenses in the shower, swimming pool, or hot tub. Water can introduce harmful bacteria to your eyes.

  • Blink frequently and use artificial tears to keep your eyes moist, especially in dry environments.

  • Take breaks from contact lenses if you experience redness, irritation, or dryness.

  • Visit your eye doctor regularly for comprehensive eye exams and lens prescription updates.

Final Thoughts

Proper contact lens hygiene is essential for preventing infections and maintaining clear, comfortable vision. By following the correct cleaning procedures, avoiding common mistakes, and replacing your lenses and case as recommended, you can enjoy the benefits of contact lenses without compromising your eye health.

If you experience persistent eye discomfort, redness, or vision problems, consult an eye care professional immediately. Taking care of your contact lenses means taking care of your eyes!
