Little one likes them, but still too big

He is younger than the age listed, but hey do fit him, and he likes them, but being a toddler they don't last long, but the sunnies are sturdy and miraculously the lenses haven't scratched even though they have a tendency to fly onto the floor often...time will tell

An anti-UV material, but what is it for? To protect your eyes from an invisible danger... UV rays. UV radiation is always present, in winter or summer, in sunny or even cloudy weather, and it can be harmful to your eyes and their contours. To preserve your vision, the lenses of our sunglasses are made of polycarbonate mixed with an "anti UV" material that protects you from the harmful rays of the sun (UVA and UVB).


Classification of tinted lenses according to the ISO 12312-1 standard: - Category 1: lens with a light tint for reduced sunlight. - Category 2: lens with a medium tint for average sunlight. - Category 3: dark lens for strong sunlight (sea and mountains). Between 82% and 92% of visible light absorbed - Category 4: very dark lens, for exceptionally strong sunlight (high mountains). Between 92% and 97% of visible light absorbed

Good to know

Our lenses are made from polycarbonate, a very durable shock-resistant material with 1 major inconvenience: it is sensitive to scratches. Bear in mind that even if your lenses are scratched, the UV protection does not decrease; The mirror effect is purely for aesthetic purposes. The same goes for the color of our tinted lenses. Whether they are gray, brown, or colored… you can choose your glasses according to your taste and you will still be protected, whatever the color.

Our environmental approach

Because we are aware that we must act to preserve our playground, Quechua is committed to limiting the environmental impact of its products. Today, this product is not eco-designed, but we work every day to make it more responsible: Eco-design, repairability, and durability are at the heart of our development process.


Polyester and plastic Easy-to-adjust buckle system.



Product testing

All our sports glasses are tested in our DECATHLON laboratories and in the real conditions of use for which they were designed. The design teams – product manager, engineers, and designers – ensure that our sports glasses are perfectly suited to their use in the field.

Storage instructions

Kids' quality of vision depends on taking proper care of their glasses. The case is essential! Keep your glasses in their case to avoid scratches, knocks, and crushing.

Care instructions

Clean your lenses with a suitable accessory: towelette, microfiber cloth or lens cleaner (ORAO accessory range). Avoid using paper towels, cloths that contain silicone or tissues as they may scratch your lenses. Household products, disinfectants and acetone may also damage your lenses and their surface treatment. In the event of splashes on your lenses, never dry-wipe them: rinse with clear water first.
