What are the screening tests?
These tests are presented as games and usually take about 15 minutes. There is no conceivable risk. Public Health will send a letter with the results either by mail or with the child.
If I'm told that my child should see an optometrist, does that mean something is wrong?
Not necessarily. The odds of a problem are roughly 50:50.
Our child wears glasses yet the screening test found a problem while he's wearing them. Why?
If your child has worn glasses for awhile, the prescription may need to be changed. Call your optometrist to book a check-up.
If the glasses are recent, your child may still be adjusting to them. Your child might also have been developing amblyopia before getting the glasses and needs time to catch up. (See risks of amblyopia below.) If your child has worn the glasses for more than a few months, call your optometrist for advice.
Our family doctor sees nothing wrong with my child's eyes yet the screening test does. Why?
Eye problems are rarely obvious in young children. Testing eyes properly requires specialized training and equipment that family doctors lack.
If the screening tests found nothing wrong with my child's eyes, does that mean everything is okay?
Probably but not certainly. The odds are roughly one in 15 that the screening tests missed a problem. To be sure you need to take your child to an optometrist for a complete eye exam. For children, OHIP will cover the cost of one optometric exam every 365 days.
What does an eye exam entail?
The optometrist has your child look into various machines and she peers into the child's eyes with a light. Since it is hard to see inside a child's eye, the light is bright and the doctor uses eye drops to enlarge the pupil. None of this is painful, although the light and drops may be uncomfortable. A complete exam takes about an hour, including time spent waiting for the drops to take effect.
Are the eye drops necessary? Are they dangerous?
The eye drops are necessary to diagnose far-sightedness, which is much the most common eye problem among kindergarteners. They are not dangerous. Nobody enjoys them but they are essential and routine.

If my child needs glasses, how bad is his vision?
Adjust the size of the image below (or move in and out) so that you can read the top line but only just. Now the second line shows how a far-sighted child might see the letters in a book or how a near-sighted child might see writing on the blackboard. The third line shows how an astigmatic child might see both.
This illustrates the vision of children who need only modest correction. Your child may see worse than this.
Why does my child need glasses? Nobody else in my family has needed them.
For perfect vision every part of each eye must always grow at exactly the same rate. This does not always happen. Just as different parts of the body can grow at different rates, so can different parts of the eye.
Growth is affected by genes and the environment. The key environmental factor affecting the eye's growth and need for glasses seems to be the amount of sunlight a child experiences while growing up—i.e., the amount of time the child spends out of doors.
Why not give my child a few years to see if he or she grows out of the problem?
Because, depending upon the problem, either his schoolwork may never recover or he may lose the use of an eye.
Can't glasses weaken the eyes?
No. Here's a sensible discussion of this by the BBC.
What about exercises?
Some eye problems involve weaknesses that exercises can fix. Those are muscular or neurological weaknesses, and an optometrist will prescribe exercises for them when appropriate. However, most people need glasses because the shape of the eye is imperfect. No form of exercise can reshape the eye.
Doesn't this programme cost the government a lot of money?
No, it saves the government a lot of money. If glasses prevent one child from repeating a grade, that will save enough money in schooling to pay for full eye exams for 140 children. If glasses enable one child to cope with schoolwork instead of becoming a behaviour problem and turning delinquent, the courts and jails will save even more.
