Vision Care and Eyewear Eligibility Under Section 118.2

A closed list names only specific categories that can qualify, and it works like a tax statute. An expense qualifies for the medical expense tax credit only if subsection 118.2(2) names it. You can't just say something served a general medical purpose and expect that to carry the claim. The expense has to land in a named category, or it doesn't count.

Vision care falls into two separate paragraphs of that list, and each one works on its own logic. Paragraph 118.2(2)(j) covers eyeglasses, contact lenses, and other devices built to treat or correct a defect of vision, and every item under this paragraph needs a prescription from a medical practitioner, an oculist, an ophthalmologist, or an optometrist. Paragraph 118.2(2)(a) covers fees paid to a medical practitioner, and this is the paragraph that makes eye exam fees and laser surgery costs eligible.

Both paragraphs trace back to the same idea: an expense qualifies when it corrects or treats a condition, and a prescription or the nature of the professional service itself confirms that purpose. That single thread, corrective or therapeutic intent backed by professional authority, is what separates a legitimate claim from a rejected one. It also explains why the line between what counts and what doesn't can look so narrow from the outside. Two items that look almost identical on a store shelf can land on opposite sides of that line, depending entirely on whether a prescription exists behind them. Small differences in paperwork can decide large differences in outcome, so you need to map that boundary carefully.

What qualifies: the full set of eligible vision expenses

Every eligible vision expense shares one trait: it's either a prescribed corrective device or a professional service tied to diagnosing or treating a vision condition. Here are the specific categories that meet that bar.

When you buy prescription eyeglasses, the frames and lenses count together as a single claim. Income Tax Folio S1-F1-C1, at paragraph 1.89, confirms that the cost of frames and lenses are both eligible under paragraph 118.2(2)(j). Repairs to prescription lenses or frames aren't explicitly listed under that paragraph in the Folio, so claimants shouldn't assume a repair bill automatically carries the same eligibility as the original purchase.

Prescription contact lenses qualify under that same paragraph, counted as an other device for the treatment or correction of a defect of vision.

Prescription sunglasses qualify, but only when the prescription exists specifically to correct a defect of vision under 118.2(2)(j). If an optometrist prescribes sunglasses just to manage photosensitivity or block UV light, that recommendation alone doesn't make them qualify.

Prescription swimming goggles qualify too. The Folio names them directly at paragraph 1.89 as a qualifying vision device, so a parent buying corrective swim goggles for a child has a legitimate claim, not a gray area.

Eye examination fees qualify under paragraph 118.2(2)(a), because you pay them to an authorized medical practitioner. Optometrists count as authorized practitioners in every province and territory, so a routine eye exam at a local optometry clinic counts the same as one performed by an ophthalmologist.

Laser eye surgery and related refractive procedures qualify under the same paragraph, as a medical service. Pre-surgery and post-surgery consultations count as part of that service, not as a separate expense that needs its own justification.

Hearing aids built into eyeglass frames get a specific rule of their own. Under paragraph 118.2(2)(i), the hearing aid component and the eyeglass frame qualify as one.

What does not qualify: the hard exclusions

The pattern that disqualifies a device is the absence of a corrective prescription. The pattern that disqualifies a service is the absence of medical necessity. Both patterns recur across the exclusions below.

Non-prescription reading glasses don't qualify. It doesn't matter how genuinely a person needs them to read a menu or a prescription label. If you don't have a prescription behind the purchase, the item sits outside paragraph 118.2(2)(j).

UV protection doesn't make non-prescription sunglasses qualify, even when the packaging advertises it as an eye health feature. A 2004 CRA technical interpretation addressed this directly: sunglasses prescribed by an optometrist to treat photosensitivity were still found ineligible, because the CRA determined the glasses protected the eyes from sunlight rather than treating or correcting a defect of vision.

Eye drops you buy over the counter are non-prescription, so they generally don't make the eligible list. Contact lens solution used alongside prescription contacts may still qualify as a related supply, because it's tied directly to an eligible device.

Cosmetic contact lenses without a corrective prescription don't qualify. The device has to correct a diagnosed refractive error, not just change eye color or style.

Subsection 118.2(2.1) excludes cosmetic eye procedures outright and rules out amounts you pay purely for cosmetic purposes. The exception runs the other way: a procedure required for medical or reconstructive reasons stays eligible even if it also happens to improve appearance.

Three items practitioners most often get wrong

The boundary Section 118.2 draws produces the same handful of mistakes repeatedly, because people read the form of an item, like sunglasses or blue-light glasses, as a signal of eligibility. The prescription content behind the item decides the question.

The first edge case involves blue-light filtering glasses. If an optometrist recommends a blue-light coating for eye strain, it still doesn't qualify when added to non-prescription glasses. The CRA's rule covers expenses that treat a diagnosed visual impairment, so a recommendation alone isn't enough to meet the standard. Many people assume that if an optometrist recommends an item, it automatically clears the bar. It doesn't clear the bar. The filter coating doesn't disqualify an otherwise eligible device; it just rides along on the eligibility the prescription already established.

The second edge case involves prescription sunglasses. Claimants often assume the sunglass form factor rules the claim out by default, because they carry over the logic from the non-prescription exclusion above. The tint has nothing to do with eligibility. A corrective prescription is what places the item under paragraph 118.2(2)(j), regardless of how dark the lenses are or what they look like.

The third edge case involves refractive surgery beyond LASIK. Some claimants assume eligibility stops at the procedure they've heard of most, but the current eligible expense list confirms that PRK, SMILE, LASEK, ICL, and refractive lens exchange all qualify under the same paragraph as LASIK. These procedures often cost a lot in a single tax year, so missing them from a claim can mean missing a lot of eligible spending.

The pattern across all three cases points to the same question: does a corrective prescription actually exist behind the item or procedure? When that question has a clear answer, you usually know the eligibility answer too.

METC threshold and the value of vision claims

Qualifying for the eligible list is necessary, but it isn't enough on its own to produce a tax credit. The medical expense tax credit is non-refundable, and it only generates savings on the portion of expenses that clears an annual threshold. That means how a claim is structured matters just as much as what sits inside it.

The threshold itself is the lesser of 3% of net income or an indexed fixed dollar amount set each year. Once your eligible medical expenses clear that threshold, the credit applies to the amount above it, at the lowest federal tax rate plus the applicable provincial rate, and together these usually add up to somewhere between a fifth and a quarter of the qualifying amount above the threshold.

Picture a modest income earner whose only vision expense in a year is a pair of prescription eyeglasses. That cost alone often falls short of the 3%-of-income threshold, so you have nothing to claim. Now add a one-time LASIK procedure in that same stretch of time. The combined total can clear the threshold easily, even if the eyeglasses alone never would have.

That's where you can turn the flexible 12-month claiming window into a real planning tool. A claimant can choose any 12-month period ending in the tax year, not strictly the calendar year. Grouping a year of ordinary eyeglass costs together with a one-time surgical procedure inside a single chosen window can push the combined total over the threshold, generating a credit that neither expense would have produced sitting alone.

The non-refundable structure carries a real limitation. A person with little or no tax payable gets no benefit from the credit no matter how large the eligible expenses are. A refundable medical expense supplement exists for some lower-income earners, but it has its own separate income conditions, so it doesn't substitute for the credit in every case.

Eligible claimants and required records

The medical expense tax credit reaches a defined circle of people, not just the person filing the return, letting one claimant combine vision expenses across an entire household into a single claim.

Eligible claimants include the individual filing the return, their spouse or common-law partner, and their dependent children under 18 at the end of the year. Other dependants, including parents and grandparents who rely on the claimant for support, can also be claimed, though they go on a separate line of the return rather than being grouped with the immediate family total. Every expense included in the claim has to fall inside the same chosen 12-month period, regardless of which family member it belongs to.

The CRA's documentation requirements stay the same across every vision expense category, whether it's a routine eye exam or a surgical procedure. A valid receipt needs the patient's name, the date and a description of the service or device, the provider's name (the company or individual paid), and the name of the medical practitioner who prescribed the purchase or performed the service where one applies. It also needs the total amount paid along with confirmation of payment. If insurance covered part of the cost, only the unreimbursed portion can be claimed.

Receipts from optical retailers, optometrist offices, and surgical clinics all follow this same format, so you don't need any special CRA form if you keep the receipt itself. A missing receipt for a procedure like LASIK, which can represent a single significant expense, raises audit exposure precisely because of its size.

HSA coverage of vision expenses for small business employees

An employee benefit plan that reimburses health costs directly covers largely the same list of vision expenses as the medical expense tax credit, so if you're paid through a small business, it gives you a parallel route to the same benefit. Eye exams, prescription eyeglasses, prescription contact lenses, prescription sunglasses, lens repairs, laser eye surgery, and the full range of refractive procedures all show up as common eligible HSA expenses. The same boundary lines apply here too: prescription swimming goggles qualify, while non-prescription sunglasses and cosmetic contacts don't.

The practical difference between the two systems comes down to timing. If you claim vision expenses through an HSA, you get reimbursed directly, with no threshold to clear and no need to let expenses accumulate before you see any benefit. The medical expense tax credit works differently: a claimant has to exceed 3% of net income or the annual fixed cap before any credit materializes. For a small business employee with routine eyeglass costs rather than a single large surgical expense, that difference can mean the gap between getting reimbursed every year and getting nothing most years.

One rule keeps the two systems from overlapping: an employee cannot claim the medical expense tax credit and an HSA reimbursement for the same dollar of spending. Only the unreimbursed portion of an expense stays eligible for the personal tax credit, so it's worth tracking carefully which costs went through the HSA and which didn't before tax season arrives.
