Hydrogen peroxide lens solution

Hydrogen peroxide lens solution is a care system for soft contact lenses that uses a 3 per cent solution of hydrogen peroxide (H₂O₂). The system works in two stages: first, the hydrogen peroxide disinfects the lenses; then, through a neutralisation process, it is converted into a harmless saline solution.

The neutralisation process is essential. Without neutralisation, the hydrogen peroxide would sting and cause irritation if it came into contact with your eye. Neutralisation usually takes place using a special tablet, a coating in the lens case or a built-in catalyst, depending on the brand and system you use.

Hydrogen peroxide systems do not contain preservatives, which may make them suitable for people who are sensitive to such substances. The system is used for the daily cleaning and disinfection of soft lenses, and you should follow the manufacturer’s instructions when using it.

Hydrogen peroxide lens solution is used for the daily cleaning and disinfection of soft contact lenses. The system is designed to remove protein residues, lipids and other deposits from the lens surface, and to disinfect against microorganisms.

As peroxide systems do not contain preservatives, they are often chosen by people who are sensitive to the preservatives found in all-in-one solutions. Please note: you must always complete the neutralisation process in full, following the instructions for use; otherwise, the solution may not be safe for contact with your eye.

At SMEYEL , you’ll find various peroxide solutions for soft contact lenses, each with its own neutralisation system and instructions for use. Always check that the system is suitable for your type of lens, and follow the minimum disinfection time specified by the manufacturer.

Use and neutralisation

Using hydrogen peroxide lens solution requires care. You place the lenses in the special lens case, fill it with the peroxide solution and leave the system to stand for the prescribed time, usually at least six hours. During this time, the lenses are disinfected and neutralised.

Never place the lenses directly into your eye after they have come into contact with non-neutralised hydrogen peroxide. Always check that the neutralisation process is complete before inserting the lenses. Most systems indicate this by a colour change or a tablet that has dissolved.

Store the solution at room temperature and use the lens case and neutraliser as instructed. Some systems require you to replace the lens case regularly.
