Quick facts
- United States: non-prescription magnifiers are classified under 21 CFR 886.5840 as "magnifying spectacles," a Class I device, while prescription lenses sit under 21 CFR 886.5844, also Class I. They are two separate entries for two different products.
- United States: the spectacle frame is its own entry, 21 CFR 886.5842, Class I, and it is classified apart from the lens.
- Canada: there is no named entry for reading glasses. A spectacle lens is a non-invasive device and is Class I under the Medical Devices Regulations, Schedule 1, Rule 7(1).
- Canada: even a Class I device attracts duties. Section 21(1) of the regulations requires a label that names the device, the manufacturer and the identifier before the device is imported or sold.
- Canada: the establishment licence regime in section 44 applies to importing and selling, which is why an importer of Class I readers holds a licence rather than a device licence.
- Both countries: reading glasses are bought by dioptre, and the dioptre marking on the lens or arm is part of what makes the product what it is, not a decoration.
Readers are the quietest product in the eye care catalogue, and that is exactly why they cause paperwork problems. They look like a consumer item, they are often bought in bulk for a lobby or a resident programme, and they still carry a device classification on one side of the border and a named product entry on the other. This article sets out where a pair of readers lands in Canada and in the United States, what separates an over-the-counter reader from a prescription lens, and what a buyer should keep on file when the same order ships into Ontario and into a US state.
How do Canada and the United States classify a pair of reading glasses?
The United States names both products, and the two names matter. 21 CFR 886.5840 covers "magnifying spectacles," the non-prescription reader that a buyer picks up by dioptre without an eye examination. 21 CFR 886.5844 covers the prescription spectacle lens, the lens that is made to a written prescription. Both are Class I devices, but they are not the same entry, and a supplier that describes a magnifier as a prescription lens is describing the wrong product.
Canada classifies by rule rather than by name. A spectacle lens is a non-invasive device, and the Medical Devices Regulations, Schedule 1, Rule 7(1) states that, subject to the subrule that follows, "all other non-invasive devices are classified as Class I." Because there is no Canadian entry that singles out magnifying spectacles, the reader and the prescription lens reach the same class by the same route — Rule 7(1).
The difference between the two countries is therefore structural rather than substantive. The United States has a distinct product name for the magnifier and a distinct one for the prescription lens; Canada has one non-invasive rule that both fall under. Neither country treats a reader as a higher-class device, and neither requires a premarket clearance for a plain reader.
| Item | Canada | United States |
|---|---|---|
| Non-prescription reader | Class I, MDR Schedule 1, Rule 7(1) | Class I, 21 CFR 886.5840 magnifying spectacles |
| Prescription spectacle lens | Class I, Rule 7(1) | Class I, 21 CFR 886.5844 |
| Frame | Classified with the assembled device under Rule 7(1) | Separate entry, 21 CFR 886.5842, Class I |
| Premarket clearance | Not required for Class I | Not required for these Class I entries |
| Labelling duty | Section 21(1): device name, manufacturer name and address, identifier | General labelling controls for Class I devices |
What duties attach to a Class I reader in Canada?
Class I is the lightest class in the Canadian scheme, and that leads importers to treat it as unregulated. It is not. Section 21(1) of the Medical Devices Regulations states that "no person shall import or sell a medical device unless the device has a label that sets out" a defined list of information, including the name of the device, the name and address of the manufacturer, and the identifier of the device. A bulk carton of readers with no label, or with a label that names only a brand, does not meet that requirement.
The second duty is the establishment licence. The regulations place the licensing obligation on the person who imports or sells, which is why an importer of Class I readers holds a medical device establishment licence rather than a device licence. A device licence is the instrument for Class II, III and IV devices; the establishment licence is the instrument that covers the import and sale activity itself, and it is the licence that a distributor of readers is most likely to need.
| Duty | Canada | United States |
|---|---|---|
| Device licence | Not required for Class I | Not required for these Class I entries |
| Establishment registration | Establishment licence under section 44 for importing or selling | Establishment registration and device listing for the manufacturer or importer |
| Labelling | Section 21(1) list | General labelling controls |
| Premarket submission | None | None for these Class I entries |
| Quality system | Manufacturer obligation under section 9 | Manufacturer obligation |
How do the Canadian and American rules treat a powered or linked eyewear product?
A passive reader sits comfortably in Class I on both sides of the border because it does nothing but refract light. A powered product is a different question, and both countries have a rule for it.
In Canada, Rule 7(2) lifts a device out of Class I if it is intended "to act as a calibrator, tester or quality control support to another medical device" or "to be connected to an active device that is classified as Class II or higher." An eyewear product that links to a Class II system can therefore be raised to Class II by the connection it is designed to make.
In the United States, an active eyewear product is classified on what it does rather than on the category of the lens. A device that emits energy, measures a physiological process or is marketed for a therapeutic purpose is assessed against the entry that fits that function. The practical lesson is the same in both countries: the presence of electronics, or a link to another device, moves the product out of the passive reader category, and the file should record which function the product performs.
Which standard describes the lens and the frame?
Two parts of the reading glasses product are specified by standards rather than by regulation. ISO 8980-3 covers transmittance specifications and test methods for uncut finished spectacle lenses, which is the document behind a claim about light transmission. ISO 12870 covers spectacle frames, including the requirements that a frame must meet before it is placed on the market.
For a buyer, the standard reference and the device classification answer different questions. The standard says what the lens or frame must be; the regulation says what class the finished product is in and what paperwork follows it. A supplier pack that carries both is a supplier pack that can be defended at an inspection.
What should a buyer record for a reading glasses order?
Five records, each tied to a clause.
- The product description. Whether the line is a non-prescription magnifier or a prescription lens, in the supplier's own words, because the US entries differ.
- The dioptre marking. The power marked on the lens or arm, and the range ordered, since the marking is part of the device label.
- The classification position. Class I in both countries, with the route recorded — Rule 7(1) in Canada, the named entry in the United States.
- The label. The section 21(1) information in Canada and the general label controls in the United States, checked on the delivered carton.
- The licence or registration. The establishment licence for a Canadian importer or seller, and the establishment registration and listing for a US manufacturer or importer.
Which consumables sit beside reading glasses on a clinic order?
Eye care is ordered as a set, and the eyewear line travels with the bench consumables and the examination tools that share the same cycle. For clinics buying at case level, the wholesale ordering page sets out account and case terms, and the B2B wholesale collection lists the lines held for institutional buyers. The CliniEco eye care range gathers the eyewear and examination lines, and a site that wants the readers and the eye examination stock together can start from the blue light blocking glasses two-pack, the eye test chart set or the biological indicator five-pack trial for sites that also run their own sterilizer.

Frequently Asked Questions
What class are non-prescription reading glasses in the United States?
They are Class I. 21 CFR 886.5840 covers magnifying spectacles, the non-prescription reader, and 21 CFR 886.5844 covers the prescription spectacle lens separately.
What class are reading glasses in Canada?
Class I. A spectacle lens is a non-invasive device, and Schedule 1, Rule 7(1) of the Medical Devices Regulations places all other non-invasive devices in Class I.
Does a Class I reader need a licence in Canada?
A device licence is not required for Class I, but the person who imports or sells the device needs a medical device establishment licence, and the device must carry the section 21(1) label information.
What labelling does Canada require for a reading glasses order?
Section 21(1) requires the device name, the manufacturer name and address, and the device identifier, among other items, before the device is imported or sold.
Are prescription and non-prescription readers the same product?
No. The United States classifies them under different entries, 886.5840 for magnifying spectacles and 886.5844 for prescription spectacle lenses, and a supplier pack should state which one the line is.
When does an eyewear product leave Class I in Canada?
Rule 7(2) raises it when the device is intended to act as a calibrator, tester or quality control support for another medical device, or to be connected to an active device classified as Class II or higher.
