Craftsmanship

Each pair of Belle Solaire sunglasses is handcrafted in Southern Italy.

Crafted in traditional ateliers, each frame undergoes careful hand polishing and precise assembly to ensure durability, comfort, and long-lasting quality.

Designed in Switzerland. Crafted in Italy.

Material

The frame is made from high-quality Italian cellulose acetate, known for:

  • Deep, uniform colour
  • Smooth, polished finish
  • Lightweight yet structured feel
  • Comfortable all-day wear

Derived from natural fibres such as wood pulp and cotton, cellulose acetate offers a refined alternative to conventional petroleum-based plastics.

For more information on the high-quality materials we use, including cellulose acetate, visit our FAQ page.

Lenses

  • 100% UV protection
  • Clear, comfortable vision
  • Balanced tint suitable for everyday use

Designed to provide full UV protection while maintaining natural clarity throughout the day.

Size & Fit

Portofino features a softly rounded cat-eye silhouette designed to flatter a wide range of face shapes.

Balanced proportions offer a comfortable fit for most face sizes, while adding subtle structure and elegance.

On very narrow faces, the frame may create a slightly more oversized look.

Care Instructions

  • Clean lenses with a soft microfiber cloth
  • Avoid alcohol-based or harsh cleaning products
  • Store in a protective case when not in use
  • Protect from excessive heat (for example, leaving them in a hot car), as cellulose acetate can soften and lose its shape at high temperatures

If the fit changes over time, contact us for guidance. Alternatively, a local optician can adjust the frame for optimal comfort.
