Understanding Hydrogen Peroxide As A Cleaning Agent

Hydrogen peroxide (H2O2) is a pale blue liquid that appears colorless in dilute solutions. It is a strong oxidizer, making it an effective cleaning and disinfecting agent. When used as a contact lens solution, hydrogen peroxide breaks down protein deposits, lipid residues, and other debris. Those can accumulate on lenses during wear.

The antimicrobial properties of hydrogen peroxide help kill bacteria, fungi, and viruses that may contaminate contact lenses and potentially cause eye infections. In addition, hydrogen peroxide is known for its ability to remove biofilms. Biofilms are clusters of microorganisms that can form on the lens surface and lead to infections or discomfort.

Safety is a priority when using hydrogen peroxide to clean contact lenses. It is crucial to follow the instructions provided with your hydrogen peroxide cleaning system carefully, as direct contact with undiluted or unneutralized hydrogen peroxide can cause eye irritation or damage.

Comparing Hydrogen Peroxide To Other Contact Lens Cleaning Solutions

Multipurpose solutions:

These solutions are designed to clean, rinse, and disinfect contact lenses in one step. They are convenient and easy to use but may not be as effective as hydrogen peroxide at removing stubborn protein deposits and biofilms.

Saline solutions:

Saline is a simple solution of salt in water, primarily used to rinse and store contact lenses. It does not have the cleaning or disinfecting properties found in hydrogen peroxide or multipurpose solutions.

Enzymatic cleaners:

These cleaners use enzymes to break down protein deposits on contact lenses. They can be effective in removing protein buildup but do not offer the same level of disinfection as hydrogen peroxide solutions.

When choosing a contact lens cleaning solution, it is essential to consider factors such as convenience, effectiveness, and compatibility with your specific lens type. Hydrogen peroxide stands out for its ability to provide powerful cleaning and disinfection, making it an excellent choice for maintaining lens hygiene.

How to Use Hydrogen Peroxide To Clean Contact Lenses

  1. Types of hydrogen peroxide systems available

    There are various hydrogen peroxide cleaning systems on the market, such as Clear Care, AOSept, and Oxysept. These systems typically include a hydrogen peroxide solution, a lens case with a built-in neutralizer, and sometimes a separate neutralizing agent.

  2. Preparing the hydrogen peroxide cleaning system

    Before using a hydrogen peroxide cleaning system, read the manufacturer’s instructions carefully. Ensure that you have all necessary components, including the hydrogen peroxide solution, lens case, and neutralizer, if required.

  3. Cleaning and disinfecting contact lenses with hydrogen peroxide

    Follow these steps to clean and disinfect your lenses:

    1. Wash your hands thoroughly to prevent contamination.
    2. Remove one lens and place it in the appropriate chamber of the lens case.
    3. Fill the chamber with hydrogen peroxide solution until the lens is fully submerged.
    4. Repeat the process for the other lens.
    5. Close the lens case and let the lenses soak for the recommended time, usually between 4-6 hours or overnight.

  4. Neutralizing the hydrogen peroxide solution

    The neutralizing agent in the lens case (usually a platinum disc or a neutralizing tablet) will convert the hydrogen peroxide into a harmless saline solution during the soaking period. This makes it safe to insert the lenses after soaking.

  5. Storing contact lenses after cleaning

    After the soaking and neutralizing period, remove the lenses from the case and insert them into your eyes. Dispose of the neutralized solution and rinse the lens case with saline or multipurpose solution. Allow the case to air dry.

Tips For Optimal Hydrogen Peroxide

A. Choosing the right hydrogen peroxide system for your lens type

Ensure that the hydrogen peroxide system you choose is compatible with your contact lenses. Most systems work with soft and RGP lenses, but always confirm with the manufacturer or your eye care professional.

B. Following manufacturer’s guidelines for cleaning and storage

Adhere to the instructions provided by the hydrogen peroxide system manufacturer to ensure safe and effective lens cleaning. This includes following the recommended soaking time and using the appropriate neutralizing agent.

C. Recognizing signs of irritation or damage from improper use

If you experience eye irritation, redness, or pain after using hydrogen peroxide, remove your lenses immediately and consult your eye care professional. This may indicate improper neutralization or a sensitivity to the solution.

D. Handling and disposing of hydrogen peroxide safely

Handle hydrogen peroxide with care, as it can cause irritation or burns if it comes into direct contact with skin or eyes. Dispose of the neutralized solution and used neutralizing agents according to local regulations.

Frequently Asked Questions

A. Can I use hydrogen peroxide with all types of contact lenses?

Most hydrogen peroxide systems are compatible with both soft and rigid gas permeable (RGP) lenses. However, always consult the manufacturer or your eye care professional for confirmation before using hydrogen peroxide with your specific lenses.

B. How often should I use hydrogen peroxide to clean my lenses?

Hydrogen peroxide systems can be used daily to clean and disinfect contact lenses, replacing traditional multipurpose or saline solutions.

C. What if I accidentally insert a lens without neutralizing the hydrogen peroxide?

If you insert a lens without neutralizing the hydrogen peroxide, it can cause severe eye irritation, pain, and even injury. Remove the lens immediately and flush your eye with sterile saline or artificial tears. Consult your eye care professional if symptoms persist.

D. Can I mix hydrogen peroxide with other cleaning solutions?

Do not mix hydrogen peroxide with other cleaning solutions, as this can compromise the effectiveness and safety of both solutions. Always follow the manufacturer’s instructions for proper lens care.


In summary, hydrogen peroxide offers numerous benefits for contact lens care, including powerful cleaning and disinfection properties. By following proper lens cleaning and maintenance procedures, you can ensure the longevity and comfort of your lenses.

Always consult your eye care professional for personalized advice on the best cleaning solutions and methods for your specific lens type. Embracing hydrogen peroxide as part of your contact lens care routine can help you maintain optimal eye health and enjoy clear, comfortable vision.
