Everything you need to know about UV

The sun emits ultraviolet (UV) rays to which we are all exposed, whether the sky is clear or cloudy.

  • UVB rays reach the surface of the skin and are responsible for tanning and sunburn
  • UVA penetrates deep into the tissues (of the eye or skin) and accelerates its aging.

Before the age of 12, children's eyes are more permeable to UV rays. They must therefore be protected from a very young age. In a lifetime, 70% of total UV exposure is experienced before the age of 17. Children are therefore most exposed.

On a boat, on the beach or in winter sports, be careful because

  • water reflects 10 to 30% of UV rays
  • sand reflects more than 20% of UV rays
  • snow reflects 85% of UV rays

Good Anti-UV Reflexes

How to protect yourself effectively from the sun?

  • Avoid exposure to the sun in the middle of the day (12 p.m.-4 p.m.)
  • Renew the application of index 50 sunscreen every 2 hours
  • Use sunglasses, hats with large visors, and UPF 50+ anti-UV textiles for all outdoor activities
  • Favor shaded areas
  • For more information, do not hesitate to read our page dedicated to sun protection for the eyes.

How to choose glasses?

Children always look upwards, so glasses must cover the eye perfectly.

Opt for CE-certified lenses, category 3 or 4, ensuring maximum UV filtration.

Select sunglasses that are well suited to your child's age and body shape. Finally, choose lenses that filter 100% of UV rays

At what age should a child wear sunglasses?

Before 1 year, 90% of UVA and more than 50% of UVB reach the retina of the little ones, it is therefore essential to have your baby wear glasses from their first exposures.

What does Category 3 or 4 mean?

This is the protection category for the lenses of your sunglasses. Lens categories are classified from 0 to 4. For more information, do not hesitate to read our page dedicated to UV categories of sunglasses.

The lenses of Ki ET LA sunglasses are category 3 or 4 and offer maximum UV filtration. They also have a special anti-blue light treatment to reduce glare.

How to choose your hat?

  • Sunscreen, umbrellas or parasols do not replace glasses and a hat.
  • Choose a hat with large visors that protect the face, neck and shoulders as well.
  • Choose Anti-UV textiles offering maximum UPF 50+ protection.
  • Select natural materials and comfortable textiles so that the child is comfortable and keeps his hat on his head.

Why choose an Anti-UV hat rather than a classic cotton hat?

In general, a standard summer fabric is around a UPF 6 and blocks very little UV. The Ki ET LA hat with Anti-UV UPF 50+ textile guarantees to block maximum UV rays. Its wide visors help protect the shoulders and/or faces of little ones.

What do UPF and UPF 50+ mean?

UPF stands for “Ultraviolet Protection Factor”. It is an index defined for textiles with a European standard, it indicates the percentage of UV filtration

UPF 50+ guarantees very high protection since this rate blocks more than 97.5% of UVA and UVB rays. The Ki ET LA Kapel hat is made of UPF 50+ cotton: the maximum protection index against UV rays.

What is the difference between UPF and SPF?

SPF stands for “Sunburn Protection Factor”. SPF is the index which represents the level of protection of a sun product (cream, milk, mist, etc.).

UPF stands for “Ultraviolet Protection Factor” and indicates the percentage of UV filtration by the textile.

Each solar index corresponds to a percentage of UVB blocked.

The UPF 50+ rating of Ki ET LA hats and caps is the highest UV protection available today

What does the Oeko Tex label really guarantee?

All Ki ET LA hats benefit from the Oeko Tex label. This label guarantees the human-ecological qualities of textiles: free from products toxic to the body and the environment.

Everything you need to know about Blue Light

The blue light emitted by the sun is at a low level, it is a source of energy and promotes well-being.

On the other hand, artificial blue light emitted by electronic devices is very harmful to the eyes.

Artificial blue light is emitted by computer screens, tablets, televisions, consoles, mobiles, LED lights and floods our daily lives.

Blue light penetrates the eye to the front of the retina, disrupting the formation of images. The muscles of the eye must therefore continually focus to adapt, thus tiring our eyes.

This artificial blue light causes:

  • Visual fatigue
  • Itchy eyes
  • Headache
  • Mood and sleep disorder

In the long term the effects of blue light can be serious.

Children aged 6 to 12 spend an average of 3 hours a day in front of screens. The new generations are the most exposed.

Best Practices with Screens

How to effectively protect yourself from harmful screen light?

  • Avoid overexposure to screens. Health professionals recommend not using screens before the age of 2, using screens for less than 1 hour per day before the age of 4 and less than 2 hours per day after the age 5 years old.
  • In front of each screen, systematically protect your child's eyes.

How to choose your anti-blue light glasses?

  • Choose lightweight, comfortable glasses so that your child gets used to wearing them systematically
  • Choose glasses filtering between 40 and 50% of blue light.
