A true paradise for nature lovers and outdoor enthusiasts, Mont Caroux is located in the Hérault region, in the heart of the Haut-Languedoc Regional Natural Park. At its foot, the Jaur River meets the Orb, which flows into the Mediterranean Sea just a few kilometres downstream.
Inspired by this iconic landscape, our Caroux frames feature a bold, sporty design that reflects the adventurous spirit of this destination, cherished by hikers and explorers alike.

Our French, eco-friendly 100% sunglasses, made from plastic collected from the water.
Square and confident, to accompany your everyday.
A distinctive feature of these glasses is their thickness, which gives them a dynamic look.
Depending on the version you choose, your eyewear is fitted with blue light filtering lenses, reading lenses, or Category 3 polarized sunglasses with a scratch-resistant and anti-reflective coating.
Available reading lens strengths
+1.50 → Early presbyopia – approximately ages 45–52
+2.00 → Established presbyopia – approximately ages 52–60
+2.50 → Intensive reading – approximately ages 60–68
+3.00 → Advanced presbyopia – approximately 65+
These ages are for guidance only. Presbyopia varies from person to person. A prescription of +2.00 may be suitable for a wearer aged 45 or 65.
To accompany our eco-friendly glasses and care for them sustainably, we offer three accessories designed with the same approach :
A recycled microfiber cleaning cloth to keep your lenses spotless.
Optional : our recycled leather case, offering enhanced protection with an elegant finish.
Flexible, durable, and made entirely from recycled leather, our case helps extend the life of your eyewear while staying true to EIO's sustainable values.
Everything is carefully packaged in a recycled cardboard gift box.
To keep them in good condition for as long as possible, store your glasses in their protective case. Furthermore, never place them on the lenses.
Gently clean them with the microfibre cloth.
For the most stubborn stains, rinse your glasses with lukewarm water. Ideally, use demineralised water. You can also add a few drops of pH-neutral cleaner.
Over time, the arms may start to warp. If this happens, do pop into an optician’s for a fitting (this is usually free of charge).
Shipping and returns are free to pickup points. Your order is shipped within 48 hours, giving us just enough time to carefully prepare your eyewear.
If you're not completely satisfied with your new pair, you have 15 days to return it and request either a refund or an exchange.
Over time, everyday wear may require minor repairs. That's why our frames are covered by a 2-year warranty. If you need assistance, simply contact our customer service team at sav@eio.eco.
Deliveries and returns are free to a collection point. International delivery is also available 🌍.

Our frames have been designed to fit the majority of face shapes, particularly wider or more traditionally masculine faces. That's why they are available in one universal size.
