Hydrogen peroxide solutions are contact lens care systems that disinfect lenses using hydrogen peroxide rather than traditional preservatives. They are particularly useful for people with sensitive eyes or allergies.
How It Works
Lenses are placed in a special case, covered with hydrogen peroxide solution, and left for a set time while the solution kills germs and removes deposits. A built‑in neutralising disc or tablet then converts the peroxide into a harmless saline‑like liquid before the lenses are worn.
- Unneutralised peroxide must never be put directly into the eye
- Neutralisation usually takes several hours and should not be shortened
- Cases and discs need periodic replacement according to instructions
- System is for the stated lens types only and not for rinsing daily disposables
Advantages and Precautions
Hydrogen peroxide systems provide effective disinfection without long‑term preservatives on the lens surface, which can improve comfort. They require careful adherence to instructions to avoid stinging or injury.
- Ideal for some people with preservative sensitivity
- Lenses must not be topped up in old solution; fresh solution is used each time
- Travelling users should plan for neutralisation time before wear
- Discuss suitability with your eye care professional before switching systems
