Product Customer Reviews

Love them may get darker ones
These are awesome sunglasses but depends on how they fit your face. Mine fogged up a lot as they fit down touching my cheeks and that caused them to fog up. Will likely have to go with a different pair when kayaking.
Very good sun protection. Good fit for me and spend good part of the summer in them without any issues.
Of course you could spend a fortune on designer brands which you'll find a knock off version on a market stall in the med or you could buy these properly UV rated, light weight, sensible priced ones and feel like a winner. They're comfy and come with a detachable head band for those occasions when sitting by the pool doesn't get the heart rate going
Couldn't put on without them steaming up even when wearing as everyday glasses ie not skiing
Lense fell out frames just taking them out the packaging
Walked, hiked, beach and surfed using these. Don’t break the bank but are up to the task. Used daily in the last heatwave. May look for the Category 3 version for driving.
Both lenses popped out. Had this pair before which lasted a while. So I am pretty sure I must of picked up a faulty pair, returning the item this week, hopefully with or without a receipt
Hi,
Thanks you for taking the time to review our MH570 Cat 4 Sunglasses. It does sound like the pair you purchased unfortunately had a fault, normally the senses don't pop out so easily! I hope that the store was able to find a solution for you,
Regards,
Peter - Forclaz Product Expert, Decathlon UK
Brilliant sunglasses! I bought these to block out as much sun as possible due to my epilepsy and they do just that. Allows me to clearly see through, very light, great colour and stylish. The only small downfall, but my choice was I bought a harder sunglasses case, as the ones that came with the product, were flimsy and difficult to take sticker off. Over all fantastic product.
Purchases these in store at Glasgow, after trying them on, great fit, really good anti glare and quite a dark tint, excellent for bright sunny days up mountains, also used on snow days and work really well, they are comfortable and a nice close fit stopping any light getting in around the edges, the elasticated strap is very handy if your very active as it keeps the glasses secure to your head. I would highly recommend these :-)
Wore glasses whilst skiing in the French Alps and found them to be very comfortable to wear even skiing Red / Black runs at speed..very good fit reducing glare whist providing excellent visibility on blue sky days..
it was amazing experience to bought product from decathlon and this sunglasses is very usefull weather im driving or any other activity
Supar

Anti-uv
An anti-UV material, what is it for? Protect your eyes from an invisible danger... UVs. The UV radiation is still present, in the winter and summer, in sunny or even cloudy weather, and can be harmful to your eyes and their contour. To protect your vision, our sunglasses' lenses are made from polycarbonate mixed with an "anti-UV" material that protects you from the harmful rays of the sun (UVA and UVB).
Glare
Classification of tinted glasses according to the standard ISO 12312-1: - Category 1: slightly tinted lens for greatly reduced sunlight. - Category 2: medium tinted lens for average sunlight. - Category 3: dark lens for strong sunlight (sea and mountains). Between 82% and 92% visible light absorbed - Category 4: very dark lens, for exceptional sunlight (high mountains). Between 92% and 97% visible light absorbed
Good to know
Our lenses are made from polycarbonate, a very durable shock-resistant material with one major inconvenience, it is sensitive to scratches. Even if your lenses are scratched, the UV protection does not drop, the mirror effect is purely aesthetic. The same as for the color of our solar lenses. Whether they are gray, brown, or colorful... you can choose the sunglasses you prefer, you will be protected no matter what their color.
Frames made from biosourced polymer
We used Rilsan Clear G850 Rnew on these sunglasses' frame, a polymer made from castor oil. This biosourced material is a real design advantage and enables us to produce light and flexible frames.
Glasses frames with a lower environmental impact
To limit our sunglasses' environmental impact, we can also change the material. On the frames of these sunglasses, we limit the use of varnish and paint, it is all integrated in the product's mold. It isn't enough, that is why we are working so that these sunglasses are one day 100% eco-designed.

Product testing
All our sports glasses are tested in our DECATHLON laboratories and in conditions for which they were designed. The design teams, product managers, engineers, and designers make sure that our sports glasses are perfectly suited to their use in the field.
Storage instructions
The quality of your vision depends on taking proper care of your sunglasses. The case is essential! Keep your glasses in their case to avoid scratches, knocks, and crushing.
Care instructions
Clean your glasses with a suitable accessory: wipe, microfiber cloth or lens-cleaning spray (ORAO accessories range). Do not use paper towels or cloths that contain silicone or paper tissues, as these are liable to scratch your lenses. Also, do not use household cleaning products, disinfectants or acetone, which can damage your lenses and their coating. If your lenses should get sprayed, never wipe them when they are dry: Run them under clear water beforehand.
