Quick facts
- A hydrogen peroxide lens care system is a 3% hydrogen peroxide solution paired with a catalytic neutralising case that converts the peroxide to a saline solution over about six hours.
- In the United States the solution and the case are named on separate entries: the care product under 21 CFR 886.5928 for soft-lens products and 21 CFR 886.5918 for rigid-gas-permeable care, both Class II.
- In Canada a contact lens disinfecting solution is a Class II medical device and needs a medical device licence under section 32 of the Medical Devices Regulations.
- The neutralising case is not the same product as the solution; in the US the case is filed as a soft-lens accessory under its own product code, and adding or swapping a case does not by itself re-license the solution.
- Hydrogen peroxide systems are preservative-free, which is the reason they are chosen for wearers who react to preserved multi-purpose solutions.
- The entries and rule text quoted here were checked against the openFDA device classification API and the Regulations on 2026-10-06.
A hydrogen peroxide contact lens solution is a preserved-free disinfecting system that a wearer pours into a special case, where a metal disc breaks the peroxide down to saline while the lenses soak. It is used every night, it touches the surface of the eye once the lenses go back in, and on both sides of the border it is a regulated device rather than a cosmetic.
What is a hydrogen peroxide contact lens care system?
The system has three parts, and the paperwork treats them separately. The first is the solution: a hydrogen peroxide strength of about 3% that disinfects the lens. The second is the case, a vented container with a catalytic disc that starts the neutralisation as soon as the lens is dropped in. The third is the waiting time the wearer must allow — the neutralising reaction runs for roughly six hours, and lenses are not safe to insert until it has finished.
That last point is the one that catches people out. A preserved multi-purpose solution is ready when the wearer caps the case. A peroxide system is ready when the reaction is complete, and the instructions that come with the product are the only correct source of the wait time. The label is a device label, and in both countries the label wording is part of the device requirement rather than a marketing choice.
How do Canada and the United States classify a hydrogen peroxide lens solution?
The two countries reach the same class for the care product from different directions.
| Item | Canada | United States |
|---|---|---|
| Disinfecting solution | Class II device, licence under s. 32 | Class II, 21 CFR 886.5928 or 886.5918 |
| Neutralising case | Part of the licensed care product where sold as a kit | Separate entry, contact lens case under 886.5928 |
| Basis of the class | Intended to contact the eye and to disinfect a lens | Named entry and product code |
| Licence or clearance route | Medical device licence, ISO 13485 system | Premarket notification unless the entry is exempt |
| Labelling | Wording fixed by the Regulations | Wording fixed by 21 CFR 801 |
In Canada the care product is a Class II medical device: it is intended to contact the surface of the eye, and a Class II device needs a medical device licence under section 32 supported by a quality-system certificate against ISO 13485. In the United States the same product is a named Class II entry, and a product filed under that entry reaches the market through premarket notification unless the entry is exempt.
The difference that actually moves work is the case. A clinic that buys solution and cases separately, or a private-label programme that swaps the case, is changing a second device in the United States, not just packaging. In Canada the case is treated as part of the care product when it is sold as a kit.
Why is the neutralising case treated as a separate device?
Because a case is a device in its own right. The openFDA device classification API lists a contact lens case as a distinct entry under 21 CFR 886.5928 at Class II, next to the soft-lens accessories that share that regulation. A washer or a thermal lens steriliser is listed the same way.
That matters for sourcing in a way that a prescription does not. If a practice hands out a starter case with a bottle of peroxide, it is handing out two regulated items, and the labelling on each has to point to the instruction the wearer must follow. A case with no vent or a disc that has been worn out will not neutralise the peroxide, and a solution that has not been neutralised should never reach the eye.
Which standard decides whether the peroxide actually disinfects?
The efficacy question is not a class question, so it is answered by a standard rather than by the rulebook. ISO 14729 sets out the antimicrobial efficacy tests for contact lens care products: a stand-alone test for the solution on its own and a regimen test for the full cleaning-and-disinfecting routine a wearer follows. ISO 13212 covers how the shelf-life of a care product is judged, and ISO 18369 covers the lenses themselves.
Read together, the class entry and the standard answer two different questions. The entry decides whether the product can be sold; the standard decides what the instructions have to say to show the disinfection works as labelled. A clinic that keeps a short list of care products for patients with a preservative sensitivity should read the regimen claim, not the hydrogen peroxide strength alone.
What do the two rulebooks actually say?
The two texts are short, and the difference between them is the point of this article.
| Rule or entry | Wording in the source | Effect on a peroxide system |
|---|---|---|
| 21 CFR 886.5928, US | Accessories and products for soft contact lenses, including the lens case | Solution and case, both Class II |
| 21 CFR 886.5918, US | Products for contact lens care, rigid gas permeable | Class II for the RGP care product |
| 21 CFR 886.5925, US | Soft contact lenses, daily wear and disposable | The lens itself is a separate entry |
| MDR section 32, Canada | A device licence is required for a Class II device | Licence before sale |
| MDR section 45, Canada | An establishment licence for the activity | Who may import or sell |
Read together, the five lines explain why a supplier cannot move the class by relabelling. A solution described as a rinse while it is poured into a case is described against the text, not against the bottle.
Which consumables does a dispensing room restock?
A contact lens room runs on the same bench supplies as the rest of the practice. The smooth white exam table paper covers the fitting bench between patients, and the double-tipped cotton swabs handle the lid margin check that comes before a trial lens is placed. A practice that also runs its own steriliser pairs the sterilization monitoring collection with the 24-hour monitoring five-pack trial. Clinics and multi-site groups ordering at case level use the wholesale ordering page, and the B2B wholesale collection lists the lines held for institutional buyers. Reselling? become a distributor.

A count of how many care products a room opens is a count that is hard to rebuild later. The printable lens care and consumable log is a blank form with columns for the product, the lot, the strength and the date opened, so a shortfall is visible on the day rather than at the next review. The care log generator on the same page sizes the form to the number of fitting rooms a practice runs. No account and no sign-up are needed to open either one.
Every lens care setup is different. Ask a compliance specialist and you will get a written answer specific to your equipment and province, with the regulation or standard it is based on cited.

Frequently Asked Questions
Is a hydrogen peroxide lens solution a Class II device in the United States?
Yes. Soft-lens care products are filed under 21 CFR 886.5928 at Class II, and rigid-gas-permeable care products are filed under 21 CFR 886.5918, also Class II.
How does Canada classify the same solution?
In Canada a contact lens disinfecting solution is a Class II medical device and needs a medical device licence under section 32 of the Medical Devices Regulations, supported by an ISO 13485 quality-system certificate.
Is the neutralising case a separate device?
In the United States, yes. A contact lens case is a distinct Class II entry under 21 CFR 886.5928, so a programme that swaps the case is changing a second device rather than repackaging the solution.
Why does a peroxide system need a waiting time?
The catalytic disc converts the hydrogen peroxide to a saline solution over roughly six hours. Until the reaction finishes the solution is still peroxide, and the lens should not be inserted; the wait time printed on the product label is the correct source.
Does a stronger peroxide disinfect faster?
No. The disinfecting power is set by the regimen test in ISO 14729, not by making the solution stronger. A product is judged on the full clean-and-disinfect routine the wearer follows, not on the concentration alone.
Are peroxide systems preservative-free?
Yes. The disinfecting agent is hydrogen peroxide, which breaks down to saline, so no preservative has to remain in the case. That is why the systems are chosen for wearers who react to a preserved multi-purpose solution.
What does the class change for a supplier?
In Canada a Class II device needs a licence under section 32 held by the manufacturer, while the Canadian seller holds an establishment licence under section 45. In the United States the product reaches the market through premarket notification unless its named entry is exempt.
