Prevention, signs of aggravation and consequences of screens: one month after the start of the school year, Europe 1 explains to parents how not to miss their children's sight problems.

Here are three questions you won't ask yourself again.

The problem of their children's sight must be of concern to all parents.

In fact, 80% of the information given in class is visual.

In primary school, one in four pupils has a visual impairment.

Europe 1 answers the three questions that you do not ask yourself about vision problems in children.

What are the signs that should alert parents?

A child does not easily say that he cannot see clearly.

Certain behaviors of the child can nevertheless put the chip in the ear.

If he rubs his eyes, frowns, bangs regularly, parents should be vigilant.

Likewise, if the child reads or draws his nose stuck to the sheet or if he complains of a headache, he may be affected by sight problems.

Parents sometimes observe certain habits: when they see less well with one eye, the child always wants to watch TV in the same chair.

Finally, we must be even more vigilant if one of the parents himself has vision disorders because a third of the child's visual disorders are of genetic origin.

Is a visual defect spotted later likely to worsen?

Not systematically, but it is a shame to waste time and leave the child in discomfort.

A fault spotted early is better corrected.

Since visual abilities improve up to 6 years of age, it is easier to correct sight in a young child.

An undiagnosed vision problem can also cause academic difficulties.

Is the increasing use of screens increasing sight problems?

Yes and no.

Screens don't directly increase myopia, but looking too closely is problematic.

This can apply to screens as well as books or coloring.

Ideally, near vision should not be used for more than half the day.

To avoid straining the eyes, it would be necessary to alternate near vision and far vision.

When a child has had a good time in front of the TV or a screen, he should be told to go play outside.

This practice is good both for distance and also for the light which is more important outside.

This dilates the pupil and increases the depth of the field of vision, which is why there are fewer myopic cases in children who regularly exercise outdoors.
