How Often Should You Get an Eye Exam?

Medically reviewed by the Medical Advisory Council at U Vision Group.

The honest answer to how often you should have your eyes examined is that it depends on your age, your health, and what your eyes are doing right now. For most healthy adults the rhythm is every one to two years, but a child, a contact-lens wearer, someone living with diabetes, or anyone over sixty-five will sit on a different schedule. An eye exam is not only about whether you need glasses. It is a structured look at the health of the eye and, through it, a window onto conditions that show no symptoms until they are advanced. This guide walks through the recommended intervals at each stage of life, explains why those intervals exist, and helps you recognise when something warrants a visit sooner than the calendar suggests.

Why an eye exam is more than a vision check

It is easy to assume that if you can see well, your eyes are fine. Much of the time that holds, but several of the conditions optometrists watch for develop quietly. Glaucoma, for instance, damages peripheral vision so gradually that most people do not notice until a meaningful amount is gone. Diabetic changes at the back of the eye, early macular degeneration, and a rise in eye pressure can all be present while your sight feels perfectly normal. A comprehensive exam looks past the prescription to the health of the cornea, lens, retina, and optic nerve, which is why we recommend a regular schedule even when nothing feels wrong. You can read more about what each step involves on our eye exams page.

There is a second reason worth naming plainly. The eye is the one place in the body where blood vessels and nerve tissue can be seen directly, without surgery. That means a routine exam sometimes turns up the first sign of high blood pressure, diabetes, or other systemic conditions before they have been diagnosed elsewhere. The exam earns its place in your health routine on those grounds alone.

How often adults should be examined

For healthy adults between roughly nineteen and sixty-four with no symptoms and no risk factors, an exam every two years is a sensible baseline, and many people choose to come annually. The interval tightens when risk rises. If you wear contact lenses, have a family history of glaucoma or macular degeneration, take medications that affect the eyes, or have a job that is demanding on your vision, yearly is the better default. The Canadian Association of Optometrists publishes interval guidance along these lines, and your optometrist will tailor the timing to what they see.

Adults sixty-five and older should generally be examined every year. The risk of cataract, glaucoma, and age-related macular degeneration all climb with age, and an annual check gives the best chance of catching change while it is still easy to manage. If you have noticed your night vision dimming, colours looking washed out, or glare bothering you more than it used to, those are worth mentioning rather than waiting for the next scheduled visit.

Children and teenagers

Children sit on their own schedule because their eyes are still developing and because a child rarely reports a vision problem. They have nothing to compare their sight to, so blurred or double vision can read as normal to them. Current guidance suggests a first exam between six and nine months of age, another between two and five years, and then yearly through the school years. Good vision underpins reading, learning, and coordination, and an undetected problem can be mistaken for a learning or attention difficulty. We cover this in detail on our paediatric eye care page.

For children who are becoming more nearsighted, the conversation shifts from simply updating glasses to actively slowing the progression. That work — known as myopia control — is something we provide in-house, and our myopia management page explains the options. The aim is not only clearer vision today but a lower lifelong prescription, which carries real health benefits.

When health conditions change the schedule

Some conditions override the general intervals. If you have diabetes, an annual dilated eye exam is recommended regardless of age, because diabetic retinopathy can advance without symptoms and is far more treatable when caught early. A family history of glaucoma, previous eye injury or surgery, or long-term use of certain medications can all mean more frequent monitoring. Your optometrist will set the interval that fits your situation rather than applying a single rule to everyone.

It is also worth knowing where the boundary of optometric care sits. When an exam turns up something that needs surgical or subspecialty attention — a suspicious optic nerve, a corneal condition, or a retinal finding — we coordinate care with the specialists at Uptown Eye Specialists rather than leaving you to chase a referral yourself. You stay inside one connected system the whole way through.

Signs you should not wait for your next exam

A schedule is a baseline, not a rule that overrides what your eyes are telling you. Book sooner if you notice a sudden change in vision, new or increasing floaters or flashes of light, a curtain or shadow across part of your field of view, persistent eye pain, redness that does not settle, or double vision. Sudden symptoms in particular can signal something urgent, and they are always worth a prompt call rather than a wait. If your existing glasses or contacts have stopped feeling right — more eye strain, headaches, or squinting to read — that is reason enough for a visit too.

The difference between a comprehensive exam and a quick screening

It is worth drawing a clear line between a comprehensive eye exam and the brief vision screenings you might encounter at school, at work, or even at a licensing office. A screening checks one narrow thing — usually whether you can read a chart at distance — and it is genuinely useful for flagging an obvious problem. But passing a screening is not the same as having healthy eyes. A screening does not measure your eye pressure, examine your retina and optic nerve, or assess how your eyes work together, which means it can miss the very conditions that matter most. When people say “but I passed the vision test,” this is the gap they are describing without realising it.

A comprehensive exam, by contrast, is the full assessment of both your vision and your eye health, performed by an optometrist. That is the appointment the intervals in this guide refer to. If your child passed a screening at school, or you breezed through the eye test for your driver’s licence, that is reassuring as far as it goes, but it does not replace the regular comprehensive exam that catches the silent conditions. The two serve different purposes, and only one of them is a substitute for the schedule we have described.

What to expect and how to prepare

A comprehensive exam usually takes thirty to sixty minutes and is comfortable throughout. You will go through vision testing, a check of how your eyes work together, a measurement of eye pressure, and an examination of the structures at the front and back of the eye, sometimes with drops that widen the pupil. Bring your current glasses or contact lenses, a list of medications, and any notes about symptoms or family history. Because we are optometrists rather than a sales floor, the exam stands on its own — the goal is an accurate picture of your eyes, and any conversation about eyewear comes after, only if you want it.

If your eyes are dilated as part of the exam, plan for it. The drops take fifteen to twenty minutes to work and can leave your vision blurry and your eyes light-sensitive for a few hours afterward, so bringing sunglasses and arranging not to drive immediately is sensible. Beyond that, there is nothing to prepare or worry about. Every part of the exam is painless, the pace is comfortable, and you are welcome to ask about anything you are unsure of as we go. The more we understand about your eyes and your history, the more useful the visit is to you.

If you are due for a check or simply unsure where you sit on the schedule, you can book a comprehensive eye exam and we will set the right interval for you going forward. For frames and lenses once your prescription is settled, our eyewear page walks through the options without the pressure.

Frequently asked questions

How often should I get an eye exam if I have no problems? For healthy adults with no symptoms or risk factors, every two years is a reasonable baseline, though many people prefer annually. Children, adults over sixty-five, contact-lens wearers, and anyone with diabetes or a relevant family history should be examined yearly.

Is an eye exam necessary if I can see fine? Yes. Several serious eye conditions, including glaucoma and early diabetic changes, develop without affecting your vision until they are advanced. A comprehensive exam checks the health of the eye, not just the strength of your prescription.

How often should children have their eyes examined? A first exam is recommended between six and nine months, another between two and five years, and then yearly through the school years. Children often cannot tell that their vision is not normal, so regular exams catch problems they would not report.

Does OHIP cover eye exams in Ontario? OHIP covers routine eye exams for children and youth under twenty, adults sixty-five and over, and people with certain medical conditions such as diabetes. Coverage rules change, so it is best to confirm your eligibility when you book.
