Original Medicare (Parts A and B) generally does not cover routine eye exams for eyeglasses or contact lenses.
Medicare Part B may cover annual eye exams for beneficiaries at high risk for glaucoma or those with diabetes.
Many Medicare Advantage (Part C) plans offer additional benefits that include coverage for routine eye exams and prescription eyewear.
Regular eye exams become more important with age, not less — and for Medicare beneficiaries, that reality bumps up against one of Original Medicare's most frustrating coverage gaps. Eye health is closely tied to overall health, yet routine vision care falls largely outside what the federal program covers. If you're 65 or older and rely on Medicare, understanding exactly where eye exam coverage begins and ends can help you avoid unexpected costs and make a more informed decision about your plan options.
The stakes of skipping regular eye exams are higher than many people realize. Beyond detecting deteriorating vision, eye exams serve as an important window into overall health — capable of revealing early signs of diabetes, high blood pressure, autoimmune diseases, certain infections, and even cancers. These systemic conditions often manifest in the eyes before they produce more obvious physical symptoms elsewhere.
Vision loss from conditions like glaucoma, cataracts, and macular degeneration frequently develops without noticeable symptoms in its early stages — which is exactly when treatment is most effective. Waiting until symptoms appear often means waiting until the damage is already done. A comprehensive eye exam covers far more than reading an eye chart: your doctor will evaluate eye muscle coordination, peripheral vision, pupil response, color perception, eyelid function, optic nerve health, and intraocular pressure, among other measures.
In most situations, no. Original Medicare is structured around medically necessary care, and routine vision services — including standard eye exams, commonly called "refractions," for prescription glasses or contact lenses — don't qualify. If you go to an optometrist for a routine vision checkup, you're generally responsible for 100% of that cost under Original Medicare.
There are, however, meaningful exceptions where Medicare Part B does provide coverage:
For these covered services, Part B covers 80% of the approved costs after you've met your annual Part B deductible. You're responsible for the remaining 20% — an amount that a Medigap plan may help offset, depending on your coverage.
Medicare Advantage plans tell a very different story on vision coverage. Also known as Medicare Part C, these "all-in-one" private insurance plans bundle Parts A and B together and frequently include extra benefits that Original Medicare doesn't offer — dental, hearing, and vision among the most common.
In 2026, 99% of Medicare Advantage plans include vision coverage. Many plans include eye exams at little to no additional out-of-pocket cost, and some extend that coverage to eyeglass frames, lenses, and contact lenses as well.
The specifics vary considerably from plan to plan — what's covered, how often, and what your cost-sharing will look like all depend on the specific Medicare Advantage plan you select. If routine vision coverage is a priority for you, it's worth comparing plans based on their vision benefits, not just their premiums.
Medigap plans — also called Medicare Supplement plans — are designed to help pay your share of costs for services that Original Medicare covers. Because they supplement what Medicare covers, they don't extend into areas Medicare doesn't cover in the first place. Routine eye exams, eyeglasses, and contact lenses remain out of pocket regardless of which Medigap plan you hold.
Where Medigap can help: if you qualify for one of the Medicare-covered eye care services mentioned above — diabetic retinopathy exams, glaucoma tests, or macular degeneration treatment — your Medigap plan may cover the 20% coinsurance that Part B leaves behind. The extent of that coverage depends on the specific Medigap plan letter you've enrolled in.
Original Medicare's approach to vision coverage is narrow and largely limited to medically necessary conditions rather than routine care. If you need regular eye exams for glasses or contacts, those costs fall on you under Original Medicare. For individuals with diabetes or elevated glaucoma risk, targeted coverage does exist through Part B. And for those who want meaningful routine vision benefits, Medicare Advantage plans — now including vision coverage in 99% of available plans — offer the most direct solution. Knowing where these lines are drawn before you need an eye appointment puts you in a far better position to make the coverage decision that fits your actual needs.
