Contact lens solution

Contact lens solution is a care product designed to keep contact lenses clean, safe and comfortable. Soft and hard lenses come into daily contact with tears, proteins, oils and dust particles. Without proper care, these deposits can build up, which can reduce comfort and make the lens less clear. There are various types of contact lens solution, each with its own composition and mode of action. The choice depends on the type of lens you wear, your eyes and any sensitivities you may have.

Types of contact lens solution

The most common types are:

• All-in-one solutions: multi-purpose solutions that clean, disinfect, rinse and store in a single bottle. They are easy to use and suitable for most soft lenses.
• Peroxide solutions: hydrogen peroxide -based solutions that provide thorough disinfection. They require a neutralisation period of at least six hours and are suitable for sensitive eyes or in cases of protein deposits.
• Saline solutions: sterile rinsing solutions without any disinfectant properties, intended for rinsing or moistening lenses. They do not replace the cleaning or disinfection steps.
• Cleaning solutions for hard lenses: specific solutions for rigid, gas-permeable lenses, often comprising a separate cleaner and storage solution.

How does contact lens solution work?

Contact lens solution contains substances that remove dirt, inactivate microorganisms and keep the lens moist. All-in-one solutions contain preservatives and surfactants that clean and disinfect. Peroxide solutions work using hydrogen peroxide, which is converted into water and oxygen after neutralisation. Saline solutions contain only a sterile saline solution and are intended for rinsing, not for disinfection. The active ingredients and pH level are tailored to the eye and the lens material, ensuring that the solution is both effective and comfortable to use.

You use contact lens solution as part of your daily lens care routine. The exact method of use depends on the type of solution and the manufacturer’s instructions.

Cleaning and disinfecting

After removing your lenses, apply a few drops of solution to the lens and gently rub it clean with your finger, unless the solution uses a ‘no-rub’ system. You should then rinse the lens and place it in a clean lens case filled with fresh solution. The solution disinfects the lens during the recommended soaking time, which is usually at least four to six hours.

Save

Lenses that you are not currently wearing should be stored in a sealed lens case filled with fresh lens solution. Never use tap water or old solution, as this reduces the disinfectant effect and increases the risk of contamination.

Rinsing

Before inserting the lens, you can rinse it with fresh solution or a sterile saline solution. This removes any residue and prepares the lens for use.
