When you go to the store and browse the aisle with contact lens solutions, you will probably find that there are a lot of options. There are different brands, different solution types, different sizes—each with their own pros and cons. The most common types of cleaning solutions for soft contacts are multipurpose disinfecting solutions and hydrogen peroxide-based systems. The ”best” contact lens solution for you depends on your eyes, your contact lenses, and the recommendation of your eye care professional.

All about multipurpose disinfecting solution

Multipurpose disinfecting solutions are a popular choice for soft contact lens users because they conveniently handle multiple tasks in one product—cleaning, rinsing, disinfection, and storage.

How multipurpose disinfecting solution works

Multipurpose solutions generally contain chemicals called surfactants that help break down and lift away debris from the surface of the contact lenses. When you rub the lens with the solution, the surfactants bind to dirt and proteins, allowing them to be rinsed away. These solutions also have disinfecting agents that target harmful microorganisms, killing them off to help prevent infections. This approach helps ensure that your lenses are clean and ready for wearing.

Pros

Convenience

These solutions combine several functions into one product, simplifying the lens care process. This means you can clean, rinse, and store your lenses without needing multiple products, saving you time and hassle.

Cost-effective

They're typically affordable and easy to find, which makes them accessible to a wide range of users. This affordability can be especially appealing for those who wear contact lenses daily.

User-friendly

Most users find them simple to use, even if they are new to contact lenses. The straightforward instructions help guide users through the cleaning process without confusion.

Cons

Sensitivity Issues

Some people may experience irritation or allergies due to preservatives. These reactions can be mild to severe, so it’s essential to pay attention to how your eyes feel after using these solutions.

All about hydrogen peroxide solutions

Hydrogen peroxide solutions are another option for cleaning and disinfecting contact lenses. They may be particularly helpful for people who prefer preservative-free products.

How hydrogen peroxide solutions works

Hydrogen peroxide solutions work through a dual-action process. Initially, the hydrogen peroxide disinfects the lenses by breaking down harmful bacteria and organic matter. After cleaning, the solution needs to be neutralized, typically using a special case that converts the hydrogen peroxide into saline solution. This neutralization allows the lenses to be safe for your eyes upon insertion. This method is quite effective as it not only cleans but also can help protect your eyes from irritation. That said, failing to use the specialized case to neutralize the solution will cause severe stinging, burning, and injury to the eye.

Pros

Very effective cleaner

Hydrogen peroxide is a powerful cleaner that eliminates bacteria and debris. Its strong oxidizing properties ensure a thorough cleanse that many users find appealing, especially if they're prone to infections.

Preservative-free

This can be ideal for individuals with sensitivities or allergies to preservatives found in multipurpose solutions. This often makes it a preferred choice for sensitive eyes, offering a gentler alternative.

Good for deep cleaning

Often provides a more thorough cleanse for those prone to protein buildup, helping ensure that your lenses remain comfortable and clear for long periods. 

Cons

Additional steps required

Effective use of hydrogen peroxide solution involves a soaking and neutralization process to convert the hydrogen peroxide into saline, which may be seen as inconvenient. This added complexity and time can deter some users who prefer simplicity in their lens care routine. 

Risk of irritation

If not neutralized correctly, hydrogen peroxide can cause stinging, discomfort, and even a chemical keratitis. It's crucial to follow instructions closely to avoid these unpleasant experiences. 

Steps for properly cleaning your contact lenses

First and foremost, it’s important to follow the instructions provided by your eye doctor, as well as the manufacturer instructions of the contact lens cleaning solution you use. On top of that, there are some common approaches that are important for thorough cleaning.

1. Wash your hands

Start by washing your hands thoroughly with soap and water. Make sure to dry them with a lint-free towel. Clean hands help prevent the transfer of dirt and bacteria to your lenses.

2. Focus on one lens at a time

Gently take the lens off your eye and place it in your palm. This method helps to keep the lens clean, as you're less likely to drop it or expose it to contaminants.

3. Apply cleaning solution

Pour a few drops of your chosen contact lens cleaning solution onto the lens and let it soak briefly. This initial soak prepares the lens for effective cleaning by loosening any debris.

4. Rub and rinse

Always follow the exact instructions given by your brand of multipurpose disinfecting solution. Usually, this means using clean fingers to rub the lens for about 10-20 seconds, and then rinsing it thoroughly with the solution to eliminate any loosened debris. This thorough cleaning helps ensure that no harmful particles remain on the lens surface. 

5. Store Properly

Place the cleaned lens into its case filled with fresh solution. Repeat the process for the other lens and allow them to soak for the recommended time before wearing. Storing the lenses properly ensures they stay hydrated and free of contaminants until you are ready to wear them.

How to care for your contact lens storage case

Your contact lens storage case plays an important role in the hygiene of your lenses. It’s necessary to keep it clean to ensure your lenses are ready to wear after storage.

Clean it as regularly as your contact lenses

Rinse your lens case with a sterile saline solution after each use. Avoid using tap water, as it can lead to contamination. A contaminated case can transfer harmful bacteria to your lenses, so developing a habit of cleaning helps maintain hygiene.

Always, always use fresh solution

Never reuse old disinfecting solution. Reusing solution can allow harmful bacteria to thrive, which could lead to infections when you put on your lenses. 

Check it for damage

Regularly check your lens case for any cracks or wear. If you notice any damage, replace the case immediately. A compromised case may not hold the solution effectively, putting your lenses at risk.

Replace regularly

Change your lens case at least every three months or earilier if it appears dirty or cracked. Frequent replacements minimize the chances of bacteria buildup, contributing to healthier lens usage. 

Questions? Ask your eye doctor.
