Back to School: Why I Always Tell Parents to Book an Eye Exam First

Every August, the same conversation happens in our store. A parent comes in with their kid to pick out new frames, and when I ask about the prescription, they say something like: "Oh, we haven't done the eye exam yet. We figured we'd just grab some glasses." A back to school eye exam is the single most overlooked item on every parent's checklist, and honestly, it matters more than the new backpack.

I have been fitting kids with glasses for years, and I have seen firsthand what happens when a child starts the school year unable to see the board clearly. Grades slip. Confidence drops. Teachers assume the kid is not paying attention. Meanwhile, the child genuinely cannot see what everyone else sees and has no frame of reference to know that.

TL;DR: Book your child's eye exam in July or early August before clinics fill up. Kids under 19 get free annual eye exams in Alberta through Alberta Health. One in four school-age children has a vision problem that affects learning, and school screenings only catch 30 to 40 percent of issues.

Kids Do Not Know What "Normal" Vision Looks Like

This is the part most parents miss. Adults can tell you when their vision gets blurry because they remember what sharp vision felt like. Kids do not have that comparison. If a six-year-old has always seen the world slightly out of focus, that is just how the world looks to them. They will never walk up to you and say, "Hey, I think I have uncorrected astigmatism."

The Canadian Association of Optometrists reports that one in four school-age children has a vision problem significant enough to affect learning. That is roughly six or seven kids in every classroom. Some of those kids have been struggling for years before anyone catches it.

A comprehensive eye exam is the only reliable way to know. Not a school vision screening, not a parent guessing based on how close the kid sits to the TV. An actual exam by an optometrist.

School Vision Screenings Are Not Enough

I hear this one constantly: "But they passed the screening at school." School screenings are better than nothing, but they catch maybe 30 to 40 percent of vision problems. They typically test one thing: can your child read letters at a distance.

Here is what school screenings miss:

Think of a school screening as a quick temperature check. It might catch a fever, but it is not going to diagnose the underlying cause. A comprehensive eye exam is the full workup.

When to Book (and Why July Is the Smart Move)

If you are reading this in August and scrambling, you are not alone. But next year, aim for July. Here is why: optometry clinics fill up fast starting mid-August, and wait times can stretch to three or four weeks. If the exam reveals your child needs glasses, you then need another week or two for the lenses to be made and properly fitted.

By the time school starts in September, you are looking at a six-week process from booking to wearing. July gives you breathing room.

Children under 19 in Alberta get a comprehensive eye exam covered by Alberta Health once per year. Free. No excuses. All you need is a valid Alberta Health Care card. The exam takes about 20 to 30 minutes and is completely painless.

What Age Should Kids Start Getting Eye Exams?

Most parents think the first eye exam happens when the child starts school. The recommended timeline is actually much earlier than that.

Age Recommended Exam What It Catches
6 to 9 months First infant eye exam Eye alignment, major structural issues, eye health
2 to 5 years Preschool eye exam Amblyopia, strabismus (crossed eyes), farsightedness, astigmatism
6 to 18 years Annual eye exam Myopia progression, focusing problems, eye coordination, eye health changes

That first infant exam might surprise you. The optometrist is not going to hand your baby a letter chart. They use lights, toys, and specialized instruments to assess how the eyes are developing. It is quick and your baby will not mind.

The preschool exam is critical because amblyopia (sometimes called "lazy eye") is most effectively treated before age seven. After that window, treatment becomes much harder and less successful. Catching it at three or four gives you the best chance of a full recovery.

Signs Your Child Might Need Glasses

While exams are the gold standard, there are behavioural clues that might nudge you to book sooner rather than later. I have compiled these from years of conversations with parents who realized, in hindsight, that the signs were there.

Sign What It May Indicate How Obvious It Is
Sitting too close to screens or books Myopia (nearsightedness) Very obvious
Squinting frequently Refractive error (needs correction) Obvious
Head tilting or turning Astigmatism or eye alignment issue Moderate
Frequent headaches after school Eye strain, focusing problems Easy to blame on other causes
Losing their place while reading Eye tracking or coordination problem Often mistaken for reading difficulty
Covering or closing one eye Eye alignment issue, amblyopia Moderate
Avoiding reading or homework Vision makes close work uncomfortable Often mistaken for laziness
Rubbing eyes frequently Eye fatigue, allergies, or dry eyes Common but easy to dismiss

That last one — avoiding reading — is the one that breaks my heart. I have seen kids labelled as "not interested in school" or "behaviour problems" when the real issue was that they simply could not see well enough to do the work without discomfort. Once they got the right prescription, the change was dramatic.

What Actually Happens During a Kids' Eye Exam

Parents sometimes worry that their child will not cooperate during an exam. In my experience, kids do great. Optometrists who work with children are really good at making it feel like a game rather than a medical procedure.

Test What It Checks How It Works
Visual acuity How clearly each eye sees Reading letters or identifying shapes on a chart
Refraction Whether glasses are needed Looking through different lenses ("which is better, one or two?")
Eye alignment Whether both eyes point at the same spot Following a light or toy with their eyes
Eye movement tracking How smoothly the eyes follow objects Following a moving target
Colour vision Ability to distinguish colours Identifying numbers in coloured dot patterns
Eye health Internal eye structures Using a special light to look inside the eye

The whole thing takes about 20 to 30 minutes. No needles, no pain, nothing scary. For younger kids who cannot read letters yet, the optometrist uses picture charts or matching games instead. I have watched three-year-olds sit through the entire exam happily because the optometrist made it fun.

The Myopia Problem Is Getting Worse

This is something I talk to parents about more and more. Myopia — nearsightedness — is increasing rapidly among children, and researchers believe the combination of increased screen time and decreased outdoor time is a major driver.

According to the World Health Organization, myopia is projected to affect roughly half the global population by 2050, up from about a quarter in 2010. For kids, the concern is not just wearing glasses. High myopia (prescriptions over -6.00) significantly increases the risk of serious eye conditions later in life, including retinal detachment, glaucoma, and macular degeneration.

Early detection through regular eye exams means your child's optometrist can monitor the progression and potentially recommend myopia management strategies. These might include specialized contact lenses, atropine drops, or increased outdoor time. The earlier you catch it, the more options you have to slow it down.

What If They Need Glasses?

If the exam reveals your child needs a prescription, do not panic. Most kids adapt to glasses quickly, and many are thrilled because they can suddenly see things clearly for the first time. I have watched kids put on their first pair and gasp because they can read the clock on the wall or see individual leaves on a tree.

A few practical tips from years of helping parents in this situation:

Frequently Asked Questions

Are kids' eye exams free in Alberta?

Yes. Alberta Health covers comprehensive eye exams for children under 19 once per year. You do not pay anything out of pocket for the exam itself. You just need to bring your child's Alberta Health Care card to the appointment. This covers the full exam with an optometrist, not just a basic screening.

At what age should a child have their first eye exam?

The Canadian Association of Optometrists recommends the first exam between 6 and 9 months. Yes, that early. The optometrist uses infant-appropriate techniques to assess eye development and alignment. After that, a preschool exam between ages 2 and 5, and then annual exams once school starts. Most vision problems are much easier to treat when caught early.

Can a school vision screening replace an eye exam?

No. School screenings are a basic check, not a comprehensive assessment. They test distance vision only, which means they miss farsightedness, eye coordination problems, focusing issues, and eye health conditions. Research suggests screenings catch only 30 to 40 percent of vision problems. A proper eye exam checks everything.

How do I know if my child needs glasses?

Common signs include squinting, sitting close to screens, head tilting, frequent headaches after school, losing their place while reading, covering one eye, and avoiding close-up activities. But many children with vision problems show no obvious signs because they have never experienced clear vision. Routine exams are the only reliable way to know.

When should I book a back to school eye exam?

July or early August. Optometry clinics fill up quickly from mid-August through September. If your child needs glasses, you also need a week or two for lenses to be made and fitted. Booking in July gives you enough time for the full process before the first day of school.

My child passed the school vision test. Do they still need an eye exam?

Absolutely. School screenings test distance visual acuity only. Your child could pass that test and still have farsightedness, astigmatism, eye coordination problems, or focusing difficulties that make close-up schoolwork miserable. An eye exam is comprehensive. A screening is a quick look.

What happens during a children's eye exam?

The optometrist checks visual acuity, determines if glasses are needed, evaluates eye alignment and coordination, tests focusing ability, checks colour vision, and examines the health of the eye structures. It takes about 20 to 30 minutes, involves no needles or pain, and most kids actually enjoy it. For pre-readers, picture charts and matching games replace letter charts.
