Contact Lens Prescription Expired? What You Can Still Order
Contact Lens Prescription Expired? What You Can Still Order
An expired contact lens prescription blocks the order, not the boxes you already own. In Canada a contact lens is a Class II medical device, and everywhere except British Columbia a dispenser fills against a current prescription. A lapse stops a refill and a brand change. Renewal starts with an appointment: $99 for the eye exam, $135 with the contact lens fitting.
That is the short version. The longer version matters, because "expired" does not mean the same thing for every request you might make. Below is what a lapsed prescription actually blocks, what it never touched in the first place, and what the renewal appointment involves.

Does a contact lens prescription expire in Canada?
Yes, and two separate rules are doing the work.
The federal rule sets the category. Contact lenses are medical devices under the Food and Drugs Act. When Health Canada brought decorative lenses into the same category in 2015, it published the reason plainly in the Canada Gazette (SOR/2015-193): "both corrective and non-corrective contact lenses carry similar potential risks of eye injury since they interact with the eye in the same way." Corrective lenses were already Class II devices; the coloured ones joined them.
The provincial rule sets your date. There is no national number. The Alberta College of Optometrists puts it this way: "The expiration date for optical prescriptions and contact lens specifications is left to the professional discretion of the optometrist based on the medical and/or visual condition of the patient." The same guidance requires that all optometrists write "the date of issue of the optical prescription or contact lens specifications, as well as the expiry date."
So one year is common. Two years is common. Six months is normal when something about your eyes is being watched. The only date that governs you is the one printed on your own paper, which is why the tool below asks for it rather than assuming.
Put your expiry date in and see what it changes
Six things people try to do with a contact lens prescription. Three of them never depend on the date at all, which is the part most people get wrong.
No date entered yet
Enter the expiry date from your own specifications and all six rows below update to your date.
- Reorder the same brand and the same power No A dispenser fills against a current prescription, and this one is not current.
- Switch brand, or move to daily disposables No A different lens is a different fit. New fit plus lapsed date means both halves need the appointment.
- Change the power because your vision moved No The power on the paper is the power you were measured at. A change is a new measurement, not an edit.
- Get trial lenses to try something By appointment Trials come out of a fitting, never out of a reorder. This row does not change with your date.
- Keep wearing the boxes you already bought Yes The date governs dispensing, not your bathroom drawer. It does mean nobody has checked your eyes on these lenses lately.
- Order glasses using these numbers No A contact lens prescription is not a spectacle prescription, in date or not. Different numbers, different distance from the eye.
Nothing you type is stored or sent anywhere; the date stays in your browser. If your date has passed, the next step is the same almost everywhere: book the renewal.
What does an expired prescription actually block?
Only the part that involves someone handing you new lenses. Here is the same six-row logic as a flat table, for the lapsed case. Read "not filled" as the working default rather than a legal ban: dispensers are expected to work to the expiry date on the form, and any documented divergence from it is a professional judgment call made on the record, not something you can request at a checkout.
| What you want to do | With a lapsed prescription | Why |
|---|---|---|
| Reorder the same brand and power | Not filled | A dispenser is expected to fill against a current prescription |
| Switch brand or replacement schedule | Not filled | A different lens is a different fit, and a fit is measured |
| Change the power | Not filled | The power is the part that has to be re-measured |
| Get trial lenses | By appointment | Trials come out of a fitting, in date or not |
| Wear lenses you already bought | Not blocked | The date governs dispensing, not the boxes you own |
| Order glasses from the same numbers | Never | A contact lens prescription is not a spectacle prescription |
Scroll the table sideways to see every column.
The last row surprises people most often. A contact lens sits directly on the eye; a spectacle lens sits about a centimetre in front of it, so the powers are not interchangeable. A contact lens prescription also carries a base curve, a diameter and a named brand, none of which mean anything to a lens lab. You need both prescriptions, and they expire on their own dates.
One thing nobody tells you
The expiry date is a professional standard, not a switch that locks a computer. The College of Opticians of Ontario puts both halves of that on the same page. It is explicit that dispensing is discretionary in the first place: "At no time is an optician required to fill a prescription. The primary consideration should always be the best interests of the patient."
And it is equally explicit about the date: opticians "are expected to adhere to expiry dates indicated on optical prescriptions when dispensing prescription eyewear", and "any divergence from the expiry date indicated on the prescription must be recorded in the patient file, and the optician must communicate the potential risks to the patient and document the conversation in the patient file." So a lapse is not a universal hard stop; it is a judgment call, made on the record, by the person whose licence is attached to it. Which is why the answer to "can you just run it through anyway" is a conversation, not a checkbox.
Can you buy contact lenses over the counter in Canada?
No, with one province-sized exception. There is no over-the-counter aisle for contact lenses the way there is for ready-made reading glasses. Almost everywhere in Canada they are dispensed by a licensed dispenser against a prescription. But who counts as a licensed dispenser is set province by province, and British Columbia has deregulated the step after your first fitting.
The Canadian Association of Optometrists publishes the comparison. Its October 2024 summary of eyeglass and contact lens prescribing and dispensing regulations by province is the source for the table below.
| Province | To start a fitting | To buy lenses after that |
|---|---|---|
| Alberta | A valid eyeglass prescription from an optometrist, ophthalmologist or physician | From a licensed contact lens dispenser: optometrists, ophthalmologists or opticians |
| British Columbia | An optical prescription, or specifications from a sight test, then an initial fitting by a regulated professional | "CLs can be dispensed indefinitely by anyone including internet CL sites, as long as information contained in a contact lens record is provided" |
| Ontario, Quebec, Saskatchewan, Manitoba and Atlantic Canada | A valid eyeglass prescription from an optometrist, ophthalmologist or physician | From a licensed contact lens dispenser in that province |
Scroll the table sideways to see every column.
Two practical takeaways. First, an online seller's checkout behaves differently depending on where it is licensed, which is why one site waves you through and another asks for your optometrist's name. Second, across Canada with British Columbia aside, a contact lens fitting cannot even begin without a valid eyeglass prescription in hand. The CAO repeats that same sentence for Alberta, Saskatchewan, Manitoba, Ontario, Quebec and every Atlantic province, so a renewal is not a formality bolted onto a sale anywhere outside BC.
You are mid-supply and the date just passed
This is the common case, and it is not an emergency. Do three things.
- Count what you have left. A 30-pack of dailies is about a month for one eye if you wear them every day. A 90-pack is about three months for one eye. A 6-pack of monthlies is about six months for one eye. Two eyes halves it.
- Book while boxes remain. A renewal booked with three weeks of lenses left is a calm appointment. A renewal booked on the last pair is a scramble, and if the fitting changes anything the new lenses still have to be ordered.
- Do not stretch the wear schedule to make the supply last. Wearing a two-week lens for a month is the single most common way a comfortable wearer becomes an uncomfortable one. The Alberta College of Optometrists lists wearing schedules and replacement frequencies among the things patients must be instructed in for a reason.
The date is not paperwork. It is the last day someone confirmed that the lens on your eye is still the right lens for your eye.
Why a seller that never asks is the first red flag
A legitimate contact lens order asks for four things: the brand, the power for each eye, the base curve and diameter, and who prescribed them. If a checkout never asks for any of that, nobody has verified that the lens arriving at your door is the lens you were fitted in.
The Alberta College of Optometrists is blunt about the risk: "If your contact lenses were purchased from an on-line or retail company that did not personally fit them to your exact required specifications and provide appropriate and required follow-up examinations, you are at risk for potential eye damage and permanent loss of sight."
Buying online is not the problem. Buying without the fit behind it is. Charm Optical ships lenses across Canada and asks for your prescription details every time, because that is the part that makes the box on your doorstep the right box.

What happens at the renewal appointment?
A contact lens renewal is two things stacked, which is why it is priced as two things.
- The eye exam. The examination that produces the eyeglass prescription a fitting has to start from, which is the sequence the CAO sets out province by province. A comprehensive eye exam at Charm Optical is $99. AHCIP covers eye exams for Albertans under 19, Albertans 65 and over, and for specific medical conditions.
- The contact lens part. In the CAO's words for Alberta: "A CL fitting is then performed by an optometrist, ophthalmologist, physician or optician. Once the fitting process is complete, a CL prescription is determined." That determined prescription is the output you are paying for. The contact lens exam and fitting is $135, and it is not included in the $99.
You leave with the thing that unlocks every row in the table above. In Alberta, "after completing all the services required to dispense contact lenses, regulated members must offer the patient a written copy of the specifications of the contact lenses." Photograph it with your phone the moment it is in your hand. The next reorder then takes two minutes instead of a phone call.
If your lapse is measured in years rather than months, book the full exam rather than a quick recheck. A long gap means the fit, the lens material and your eye health all have to be looked at again rather than assumed, and the lens you used to wear may have been discontinued or reformulated in the meantime.

The fitting is priced separately from the exam
A contact lens exam and fitting at Charm Optical is $135, and it is not included in the $99 comprehensive eye exam. A renewal that needs both is both prices, which is worth knowing before you book rather than after. See what else is on the schedule on our services page.
FAQ
Do contact lens prescriptions expire in Canada?
Yes. Your optometrist writes an expiry date on your contact lens specifications, and that date is a clinical decision rather than a fixed national rule. The Alberta College of Optometrists states that the expiration date is left to the professional discretion of the optometrist based on the medical and/or visual condition of the patient. One year and two years are both common.
Can I still wear contact lenses I already bought?
Yes. The expiry date governs what can be dispensed to you, not the boxes already in your bathroom drawer. What the lapse does mean is that nobody has checked how your eyes are handling those lenses recently, so treat the remaining supply as a countdown and book the renewal before the last box is open.
Can I buy contact lenses over the counter in Canada?
No, except in British Columbia. Corrective and decorative contact lenses are both Class II medical devices in Canada, and in every province except British Columbia they are dispensed against a prescription by a licensed dispenser. British Columbia is deregulated after the initial fitting: the Canadian Association of Optometrists reports that there, lenses can be dispensed indefinitely by anyone including internet sites, as long as the information in a contact lens record is provided. Either way, a seller that never asks for any prescription detail is the first red flag.
How long is a contact lens prescription good for?
Read the expiry date printed on your own specifications, because that is the only date that counts for you. One year is common and two years is common, and a shorter window is normal when something about your eyes is being watched. In Alberta, optometrists must write both the date of issue and the expiry date on the form.
Is my glasses prescription the same as my contact lens prescription?
No. A contact lens sits directly on the eye and a spectacle lens sits about a centimetre in front of it, so the powers are not interchangeable. A contact lens prescription also carries a base curve, a diameter and a named brand. You cannot order contacts from a glasses prescription, and you cannot order glasses from a contact lens one.
What happens at a contact lens renewal appointment?
Two things stacked, which is why it is priced as two things. The comprehensive eye examination comes first and produces the eyeglass prescription, which the Canadian Association of Optometrists notes is what a contact lens fitting has to start from everywhere outside British Columbia. The fitting is then performed by an optometrist, ophthalmologist, physician or optician, and once it is complete a contact lens prescription is determined. At Charm Optical a comprehensive eye exam is $99 and the contact lens exam and fitting is $135, which is not included in the $99.
What do I leave the appointment with?
A written copy of your contact lens specifications. In Alberta, after completing all the services required to dispense contact lenses, regulated members must offer the patient a written copy of the specifications of the contact lenses. Photograph it with your phone so the next reorder takes two minutes instead of a phone call.
What if my prescription expired years ago?
Book a full exam rather than a quick recheck. A long gap means the fit, the lens material and your eye health all have to be looked at again rather than assumed, and the lens you used to wear may have been discontinued or reformulated in the meantime. None of the old numbers carry forward until they are verified.
The honest next step
A lapsed prescription is renewed in a chair, not in a checkout.
Book the appointment while you still have boxes left. In Alberta, once all the services required to dispense contact lenses are complete, regulated members must offer you a written copy of your contact lens specifications, and that piece of paper is what every future reorder runs on. Charm Optical is at 5035 Ellerslie Rd SW in south Edmonton, by appointment.
