All our sunglasses offer UV400 protection, blocking 100% of UVA and UVB rays. They also comply with current European standards for sunglasses.

Lens categories indicate how much visible light the lenses filter. The higher the category, the less light they let through.

Category 1: light-tinted lenses for low-light conditions.

Category 2: medium-tinted lenses for moderate sunlight.

Category 3: darker lenses for bright, sunny conditions.

Most of our sunglasses feature Category 3 lenses, while some styles with lighter lenses may be Category 1 or 2.

You can find the exact lens category for each style on its product page.

All our sunglasses offer UV400 protection. Polarised lenses also reduce glare from reflective surfaces such as water, roads and snow, making them more comfortable to wear in bright conditions.

Our reading glasses are available in five strengths: +1.0, +1.5, +2.0, +2.5 and +3.0, with the same strength in both lenses. They’re designed for near vision and are ideal for reading and other close-up activities.

If you’re not sure which strength you need, you can take our reading test to help you find the right one.

You can find the measurements of each style on its product page, helping you choose the shape and size that suits you best.

We use different materials depending on the style and collection, including polycarbonate, recycled polycarbonate, metal and acetate. Our sunglasses for children aged 0–6 are made from TPEE, a flexible and durable material particularly suited to little ones.

You can find the specific material used for each style on its product page.

Some of our styles are suitable for prescription lenses. Our acetate sunglasses can be fitted with prescription lenses by your local optician. Discover all suitable styles in our acetate sunglasses collection.

Keep your glasses in their case when you’re not wearing them and clean the lenses with a soft microfibre cloth. Avoid harsh cleaning products and don’t place your glasses lens-side down to help prevent scratches.
