Do you remember the first time your eyes landed on a screen? Probably not. And neither do we! Probably when Zelda came out on Game Boy… or even before!

Today, children are exposed very early to screens of all kinds . They are therefore victims of the blue light of these devices, without knowing the risks that this can cause.

To preserve the life points of the eyes of children, we are interested in the dangers that hide, not under the bed, but on the screens of young gamers.

The dangers of blue light on our eyes


Light is as essential to our lives as Ratchet is to Clank. However, you should also know that light breaks down into a long spectrum of colors that can be divided into two parts : a visible part which is good for our eyes and a non-visible part (UV) which is harmful to our eyes. our pupils.

The blue light sits between its two parts, much like someone who loves both Star Wars and Star Trek, so there's good and bad to know:

  • The positive part is the blue-turquoise light - it is the one that regulates our biological cycle (wakefulness-sleep) but also other functions of our body: it supports our hormonal and psychomotor properties, promotes the formation of our memory, stimulates our good mood and maintains the proper functioning of our pupillary reflexes.

  • The harmful part of the light is the blue-violet light – it is the light emitted by the sun, fluorescent lamps and white LED devices like smartphones, tablets, computers. This light is bad for the cells of our eyes.

dangers of light children's eyes

Repeated, significant and prolonged exposure to blue light causes various more or less serious manifestations on our ocular system :

  • Acceleration or worsening of age-related macular degeneration (AMD).
  • Disturbances of many body functions (see those mentioned above)
  • Chronic visual fatigue ( headaches , blurred vision, dry eyes, tingling)

Why should children's eyes be protected?


According to the Communications Regulatory Authority (ARCEP) in 2016, 93% of 12-17 year olds had a mobile phone – to which must be added exposure to computer screens, mobile tablets and long hours at walk past Animal Crossings and Minecraft.

Since then, this number has increased considerably. Young children are also increasingly exposed to the LED backlights of our screens .

So where is the problem, my dear Watson?


Well, before adolescence, the child's lens is still very fragile , it filters very little of the different waves of the light spectrum and lets blue-violet light pass (too much) to the retina.

Faced with greater exposure to this harmful light, children and teenagers whose sensitivity is greater need to protect themselves from the effects of screens.

Eliminate children's blue light sensitivity

Protecting yourself from an early age but even afterwards helps to avoid certain pathologies:

  • In the short term : avoid eyestrain , headaches, fatigue¹.
  • In the long term : avoid the risks of myopia or AMD which are due to the aggression of the retina and the lens by blue light.

¹ The quality of sleep is very important in children. Intensive exposure to screen brightness disrupts its biological cycle. Poorly restorative sleep can lead to other effects : poor concentration, difficulty remembering, bad mood, irritability, stress .


How to protect them? Our different solutions

As before jumping into the arena on Apex, you equip yourself with the best protections and weapons to defend yourself from the enemy attack. The analogy may make you smile, but in life, equipping yourself also means learning to face the enemy .

To shelter our children's pupils from the harmful threats of light, there are several practices to adopt.

Limit time in front of screens


We start with the least obvious solution: ask your child to spend less time in front of screens. Diplomacy will be in order . Pedagogy too. Good luck !

On the other hand, if it really doesn't work, and your teenager has a raging Hulk-style fit, we have other solutions for you. Follow my gaze!

Have a screen without blue light


To use a screen without blue light, filters must be used. They are an effective way to limit blue light directly emitted from its source . This filter will absorb this light wave to prevent it from reaching the eyes.

There are several types of filters: those that are applied on the screen and those used in the form of applications or software .

We have written a very specific article on this subject, which can be found by clicking on this link .

Use protective glasses

If your child or teenager wants to continue playing freely without damaging their retinas, a pair of anti-blue light glasses is the best solution . Discover the best blue light blocking glasses for children .

At least then you'll avoid all kinds of angry clashes, Street Fighter deathmatch style, between you and your "little angel".

Impose a distance in front of the screens


We don't think about it all the time, but telling your child not to be "stuck" on the screen by imposing a distance on them can prevent long-term vision problems .

Teens and children in front of screens solutions for our eyes


Based on INRS data , a distance of at least three meters in front of the television and 50 to 70 cm from a computer screen must be imposed . These are safety distances, but also of comfort, ensuring protection for the eyes. And that won't stop your little one from having a blast on Mario Kart.

Hold on to our children as the apple of their eye

Our children's eyes are more fragile than we think. They must be protected as much as possible to avoid future pathologies.

With screens that accompany their lives at all times, it is our responsibility as parents, big brothers or big sisters to adopt solutions for them as for us .

And then, if they still have to be convinced, tell them that the coolest heroes have all had a pair of glasses to protect themselves from blue light: Harry Potter, Dexter, Daria… They'll understand!
