Hello, my little lights of the future.
Hello Dr. O.D.!
Our vision is intimately connected to light.
When light enters our eyes,
it is bent and redirected toward the back of the eye.
In visual health, this change of direction of the light
is called refraction.
Watch the board!
Refraction, or light vision, is a good indicator
of visual health.
It is directly related to the light that enters our eyes.
If the refraction is good, then there is no optical defect.
However, if the refraction is deficient,
the child may have difficulty seeing far,
have to strain to see near or far, or have blurry vision.
During the vision screening at our child's school,
the optometrist will use an autorefractor
to measure the child's refraction
by asking them to look inside the device.
This test enables us to determine if the child
is near-sighted,
far-sighted, or has astigmatism.
That's all for refraction!
In closing, remember that in Quebec,
eye tests are free for children up to age 17.
Refraction (Light Vision) Signs and Effects
Distorted or poor refraction
can have an impact on learning.
Children may exhibit signs of visual fatigue,
frequently bring their hands to their face,
rub their eyes, or lack interest in tasks
that require looking at objects up close.
They may adopt a poor work posture,
bend close to their desk,
hold their paper close to their eyes,
or have red or watery eyes.
Some children may try to avoid the task,
or become restless or disruptive to the class.
Can an undetected refractive disorder affect
your educational success?
Yes, Dr. O.D.
In this light, we can clearly state that
before starting school, an eye test...
...is always best!
