Quick facts
- A diagnostic condensing lens is a named Class I entry in the United States at 21 CFR 886.1380 under product code HJL.
- The US entry is exempt from premarket notification subject to the limitations in 21 CFR 886.9, so the lens reaches the US market without a 510(k) review.
- Canada names no condensing lens. A non-invasive device that does not touch the patient is Class I under Rule 7(1) of the Medical Devices Regulations.
- The same lens is therefore Class I on both sides of the border, but the class turns on one word in the Canadian rules: whether the device is invasive.
- A lens described as coming into contact with the surface of the eye is an invasive device and moves to Class II under Rule 2(1).
- The regulation text quoted here is current to 2026-09-21 and was last amended on 2026-06-17.
A diagnostic condensing lens is the hand-held lens an ophthalmologist or optometrist holds a few centimetres in front of the eye for indirect ophthalmoscopy. It gathers light reflected from the fundus and forms a magnified image the clinician can inspect. Because it is a passive glass or plastic element, its class is decided not by power but by contact.
What is a diagnostic condensing lens?
The United States describes the device in its own words. Under 21 CFR 886.1380, a diagnostic condensing lens is a device used in binocular indirect ophthalmoscopy (a procedure that produces an inverted or reversed direct magnified image of the eye) intended to focus reflected light from the fundus of the eye.
Two things in that sentence matter. The device is passive, so the active-device rules do not apply. And its place in the procedure is optical: it sits in the light path between the clinician's viewing system and the eye. A lens that is held clear of the patient is doing one thing; a lens that is pressed onto the cornea is doing another, and the Canadian rules separate the two.
How do Canada and the United States classify a diagnostic condensing lens?
The lens is Class I in both countries when it is non-invasive, from two different directions.
| Item | Canada | United States |
|---|---|---|
| Diagnostic condensing lens, held clear of the eye | Class I by Rule 7(1) | Class I, 21 CFR 886.1380 |
| Basis named in the rulebook | Whether the device is invasive | A named entry and product code (HJL) |
| What decides the class | Contact with the patient | Which named entry it is filed under |
| Lens described as touching the surface of the eye | Class II by Rule 2(1) | Still the same named entry |
| US premarket route | Not applicable | Exempt from 510(k) subject to § 886.9 |
In the United States the lens is a named entry, and a product filed under that entry is Class I and exempt from premarket notification subject to the limits in section 886.9. In Canada the lens is not named. The Regulations instead ask whether the device is invasive. An invasive device is one intended to come into contact with the surface of the eye or to penetrate the body, and Rule 2(1) puts those in Class II. Everything else that is not otherwise caught is a non-invasive device, and Rule 7(1) puts all other non-invasive devices in Class I.
A condensing lens that is held in the light path and never touches the patient is on the non-invasive side of that line. That is the whole reason its Canadian class is Class I rather than Class II.
When does the class of the same lens change in Canada?
It changes when the intended use changes, because the Canadian text reads the contact and the claim, not the appearance of the lens.
Rule 7(1) sets the base class at I for all other non-invasive devices. Rule 7(2) lifts a non-invasive device to Class II only 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 classified as Class II, III or IV. Rule 2(1) pulls a device that touches the surface of the eye into Class II instead. A condensing lens that is described as a diagnostic tool held away from the eye stays under Rule 7(1); a lens described as contacting the surface of the eye is treated as invasive and moves under Rule 2(1).
The design rule is easy to state: read the contact, then read the exceptions. Two lenses that look identical can sit in different classes if one is labelled as a contact diagnostic lens and the other as a hand-held condensing lens. That is why the intended use statement is the single most important line on the label of an ophthalmic lens: it decides the class before any specification is read.
Which licence and records differ between Canada and the United States?
For a supplier the class is not a label; it decides which paperwork has to exist before the lens can be sold.
In the United States the condensing lens is a Class I entry exempt from premarket notification subject to section 886.9, so the lens reaches the market without a 510(k) review. In Canada a Class I device is not licensed device by device; the manufacturer holds an establishment licence under section 45 of the Regulations and keeps the records the Regulations require. A Class II or higher device instead needs a medical device licence under section 32 supported by a quality-system certificate against ISO 13485. That difference is the practical stake in the invasive question: the same lens is a Class I item with establishment records if it stays off the eye, and a Class II item needing a device licence if it is described as contacting the eye.
What do the two rulebooks actually say?
The two texts are short, and the difference between them is the whole point of this article.
| Rule or entry | Verbatim wording | Effect on a condensing lens |
|---|---|---|
| Definition, Canada | invasive device … come into contact with the surface of the eye or penetrate the body | A lens held clear of the eye is not invasive |
| Rule 7(1), Canada | all other non-invasive devices are classified as Class I | Class I |
| Rule 7(2), Canada | calibrator, tester or quality control support … Class II | Applies only to a dedicated test lens |
| Rule 2(1), Canada | come into contact with the surface of the eye are classified as Class II | Applies if the lens is labelled as a contact lens |
| 21 CFR 886.1380, US | Diagnostic condensing lens | Named Class I entry, product code HJL |
Read together, the five lines explain why a supplier cannot move the class by relabelling. A lens described as a non-contact diagnostic tool while it is placed on the cornea is described against the text, not against the product.
Which consumables does an ophthalmoscopy lane restock?
A lane that runs indirect ophthalmoscopy runs on the same bench supplies as any other examination room. The smooth white exam table paper covers the headrest and the tray between patients, and the biodegradable cotton disinfecting wipes handle the lens and instrument wipe that comes before and after a reading. A clinic that also monitors 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 lens that is wiped the same way every time is a lens whose coatings last longer than one that is not. The printable ophthalmic lens and instrument wipe log is a blank sheet with columns for the lane, the lens, the wipe used and the time, so a worn coating is spotted before it affects a reading. The wipe log generator on the same page sizes the sheet to the number of lanes a clinic runs. No account and no sign-up are needed to open either one.
Every ophthalmoscopy lane is arranged differently. 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 diagnostic condensing lens a Class I device in the United States?
Yes. A diagnostic condensing lens is a named Class I entry at 21 CFR 886.1380, filed under product code HJL and exempt from premarket notification subject to section 886.9.
How does Canada classify the same lens?
Canada names no condensing lens. A lens that is held in the light path and does not touch the patient is a non-invasive device, and Rule 7(1) of the Medical Devices Regulations places it in Class I.
When would the same lens be Class II in Canada?
If it were described as coming into contact with the surface of the eye. The definition of an invasive device includes contact with the surface of the eye, and Rule 2(1) puts invasive devices in Class II.
Does a hand-held optical instrument need power to change its class?
No. A condensing lens is passive, so the active-device rules do not apply at all. The class turns on whether the lens is invasive, not on whether it is powered.
What does the class change for a supplier?
A Class I device sold in Canada sits under an establishment licence and records rather than a device licence. A Class II device needs a device licence under section 32 supported by a quality-system certificate against ISO 13485.
What is the difference between a condensing lens and a fundus lens?
Both are diagnostic lenses used in eye examination. The condensing lens is filed under 21 CFR 886.1380; the diagnostic Hruby fundus lens is a separate entry under 21 CFR 886.1395.
Does a condensing lens need a 510(k) in the United States?
No. The entry at 21 CFR 886.1380 is exempt from premarket notification subject to the limitations in section 886.9, and a non-contact diagnostic lens reaches the market without a 510(k) review.
