It is a legitimate and very common doubt: how could a pair of discounted or low-priced sunglasses protect my eyes as effectively as a luxury model? Faced with dangerous counterfeits sold in markets or on certain non-specialized platforms, caution is necessary. However, low prices and total protection are perfectly compatible. Discover how our opticians guarantee 100% UV safety without melting your budget.
1. Price vs Protection: The Great Myth Debunked
Let's restore a technical truth that few consumers know: filtering ultraviolet (UV) rays costs almost nothing to manufacture. Today, the vast majority of solar lenses are made of polycarbonate, a lightweight and extremely resistant plastic that has the natural property of blocking 100% of UV rays, even when it is completely transparent!
Thus, when you pay €150 or €200 for a pair of glasses, you are not paying for "better UV protection". You are paying for:
- The prestige and logo of a major brand.
- The design and frame materials (titanium, handmade acetate).
- Additional comfort coatings (polarization, inner anti-reflective coating, mineral lenses).
In short: a cheap pair of sunglasses, if it comes from a certified optical circuit, protects you in exactly the same way against sun-related eye diseases.

2. The CE Mark: Your Only Real Shield
If you shouldn't rely on the price, what should you trust? Just one specific mark: the CE (Conformité Européenne) logo. This logo, which must be indelibly present on one of the temples of the glasses, is a legal guarantee.
It certifies that the frame has successfully passed the strict tests of European legislation, guaranteeing total UV protection (up to 380 or 400 nanometers) and optical lens quality (no image distortion). At Visionet, absolutely all the frames in our catalog, even those on massive clearance, carry this certification.
4. Why Are Visionet Sunglasses Cheaper?
If the protection is identical, how do we explain our prices, which are often much lower compared to a traditional store? The answer lies in our business model, not in compromises on your visual health.
- Massive purchasing volumes: As an online leader, we negotiate our stocks directly with the official manufacturers of major brands (Luxottica, Safilo, etc.), which guarantees 100% authenticity and reduced prices.
- A short supply chain: No unnecessary middlemen. Once ordered, your glasses are prepared directly in our optical workshop, then shipped to you.

"I was hesitant to order my discounted sunglasses on the internet for fear of receiving counterfeits. I received my brand name glasses with the certificate of authenticity, the engraved CE mark, and a visit to my eye doctor confirmed that the lenses were perfect. Thanks for the savings!"

Frequently Asked Questions
How can I check if my glasses really filter UV rays? +
The simplest method is to look for the "CE" logo on the inner temple. If in doubt (when buying outside official channels), any optician can test your lenses in a small device called a "lensmeter" or a UV tester to check the filtration percentage in seconds.
Does a category 4 lens protect better against UV than a category 2? +
No! The categories (from 0 to 4) only measure the amount of visible light passing through the lens (glare). UV protection is completely invisible. A CE-certified category 2 lens blocks 100% of UV rays, just like a category 4 lens.
