Triboulet Sunglasses are designed to complement a broad range of face shapes thanks to their balanced proportions and softly rounded panto silhouette. This versatile geometry naturally enhances different facial structures: it adds definition to rounder faces, softens angular ones and brings harmony to oval, heart and diamond shapes alike. The 29 mm keyhole bridge ensures comfort across various nose shapes, while the 150 mm temples provide a secure yet relaxed fit. Made from lightweight yet substantial acetate, the frame adapts gently over time, offering a combination of refined presence, balance and enduring comfort.

Sunglasses are classified by lens category, which determines how much visible light they absorb and how suitable they are for different brightness levels:

• Category 1: Lightly tinted lenses that provide minimal sun protection. Ideal for overcast days or indoor wear, but not suitable for intense sunlight.
• Category 2: Medium-tinted lenses that balance visibility and protection. Suitable for everyday use and moderate sunlight, such as city walks or partially cloudy days.
• Category 3: Dark-tinted lenses offering high protection against strong sunlight. Perfect for outdoor activities, beaches and bright summer days.
  

All Bo Bo Noir lenses feature UV400 protection, which blocks 100% of UVA and UVB rays regardless of category, ensuring full protection against harmful radiation while maintaining optical clarity and color balance.

Yes. Triboulet frame is prescription-ready, featuring a 2 mm lens groove that accommodates most optical prescriptions. For higher corrections, thicker lenses may protrude slightly, depending on the prescription’s strength and curvature. We always recommend consulting your optician or optical shop before placing an order. They can confirm the compatibility of your prescription and handle the replacement of the original sun lenses with your custom lenses.
