Frequently asked questions
Do your sunglasses provide full UV protection?
Yes. All our sunglasses feature UV400 protection, blocking 100% of harmful UVA and UVB rays. They are designed for prolonged exposure during cycling, running, skiing and outdoor sports.
What lens category are they?
Our lenses are Category 3, ideal for bright sunlight and high-glare environments. They provide strong sun protection while maintaining clear visibility during high-speed sports.
Are your sunglasses certified for sale in Europe?
Yes. Our sunglasses comply with European PPE regulations (EU 2016/425) and meet the EN ISO 12312-1 standard for sunglasses and high sun-glare protection. All required documentation and conformity declarations are available.
How do the photochromic lenses work?
Our photochromic lenses automatically adapt to UV exposure. In low light, they remain lighter for maximum clarity. Under strong sunlight, they darken within seconds to reduce glare and enhance visual comfort. The transition typically begins within 20–30 seconds and fully adjusts depending on UV intensity..
Are they suitable for intense sports and long sessions?
Yes. The frame is made from lightweight, impact-resistant materials with a secure fit and ventilation system to reduce fogging. Each pair includes a protective hard case and cleaning pouch. We ship worldwide.
