The difference between a vision screening and an eye exam
Most parents in Okotoks assume a quick check at the pediatrician or a classroom vision test is enough. It isn’t. A vision screening tells you if a child can read the top line of a chart. An eye exam tells you if their eyes can work together, focus at different distances, and track a moving object without fatigue. These are two completely different things.
When a child sits in front of a computer screen or squints at a whiteboard, they are using a complex set of visual skills that a simple letter chart cannot measure. Eye coordination, peripheral awareness, and eye-hand coordination are the mechanics of learning. If one of those gears is slipping, the child compensates. They might tilt their head, rub their eyes, or say reading is "boring." They rarely say, "My eyes are struggling to track the words."
This is why the Alberta Association of Optometrists strongly recommends annual comprehensive exams for school-age children. A screening is a useful first step, but it cannot replace the diagnostic depth of a full exam performed by an optometrist.
Why early detection matters more than you think
The visual system is still developing through childhood. If a problem like amblyopia (lazy eye) or strabismus (crossed eyes) goes undetected, the brain starts to ignore the input from the weaker eye. Once that neural pathway weakens, it is much harder to treat.
I’ve seen too many cases where a parent waited until Grade 3 because the child was "fine" in school. By then, the visual deficit had become a learning deficit. The child wasn’t struggling with the material; they were struggling to see it clearly.
Early detection isn’t just about getting glasses. It’s about catching structural issues before they become permanent. During a comprehensive exam, we assess the health of the eye and eyelid, check for signs of systemic disease that can manifest in the eyes, and measure the refractive error with precision. For infants, we start at six months. At that age, we are looking at the structure and reflexes. By the time they are two, we are assessing the ability to track and focus. This timeline matters.
Myopia control: A shift in pediatric care
Here is a trend that has changed how we approach pediatric eye care in the last decade: myopia, or nearsightedness, is rising. In Alberta, roughly 25% of children begin school with some degree of myopia, and that number is climbing.
For decades, the standard response was to prescribe stronger lenses every year and hope for the best. We now know that unmanaged myopia is a risk factor for serious eye conditions later in life, including retinal detachment and glaucoma. This is why myopia management has become a vital part of routine care.
It is not just about seeing the board. It is about slowing the elongation of the eye. When the eye grows too long, the retina stretches. That is a mechanical problem with long-term consequences.
What does myopia control actually look like in practice?
We have several tools now. Specialized contact lenses, such as Ortho-K lenses, reshape the cornea overnight. Specific soft contact lenses, like MiSight, are designed to slow axial growth. There are also specialty lenses that use a peripheral defocus technology.
These are not one-size-fits-all solutions. We have to look at the child’s lifestyle, their comfort level, and the rate of progression. If a child’s prescription is jumping 0.50 diopters a year, that is a signal to act. If it is stable, we monitor. The goal is to keep the eye from growing too fast, not to eliminate myopia entirely.
How often should your child be seen?
The short answer: annually.
Yes, even if they have no symptoms. Yes, even if they had perfect vision last year. Vision changes. Eyes grow. The demands of school and digital screens change.
A child who is visually comfortable today may develop a convergence insufficiency in six months because they are spending more time on tablets. A child with a stable prescription may develop a dry eye issue from contact lens wear. An annual exam catches these shifts before they become problems.
If your child is in the myopia control program, the frequency might be higher. We often see these patients every six months to monitor the axial length and adjust the treatment plan. Consistency is the key to success here.
What to expect during the exam
If you have never had a child through a comprehensive optometric exam, it can feel like a lot. But it is structured.
For a toddler, it is mostly about observing behavior. Do they follow a toy with both eyes? Do they have a fixation preference? For a school-age child, we use objective measures like autorefractors and subjective refraction to get the exact prescription. We check the binocular vision, the motor skills, and the ocular health.
It is not an interrogation. It is a physical assessment. The child needs to be calm, but they don’t need to perform. In fact, the best data comes when they are relaxed. If a child is anxious, their accommodation (focusing muscle) may be tense, giving us a reading that is slightly off. We account for this. We have the tools to separate true refractive error from temporary spasm.
The cost of waiting
In Alberta, eye exams for children under 19 are covered by Alberta Health Care. This is a significant benefit. For adults aged 19 to 64, you pay out of pocket unless you have private insurance. For seniors 65 and older, it is covered again.
So, for your child, the financial barrier to a comprehensive exam is low. The barrier is usually convenience. I get it. Okotoks is a growing community. Scheduling appointments around school, soccer, and work is a logistical challenge. But the cost of a missed diagnosis is much higher.
If you are unsure when to book, look at the last time you had them in. If it has been more than 12 months, book now. If they are complaining of headaches after homework, book now. If their prescription jumped more than expected, book now.
We are here in Okotoks, serving the local community. We handle direct insurance billing for most major providers, and we have a dedicated pediatric team that knows how to keep small patients engaged.
