Artisanal Craftsmanship & Structural Architecture

- Electroplated 3+2 Barrel Hinges: Reinforced electroplated metal 3+2 hinges undergo rigorous open-and-close durability testing to ensure long-term stability and smooth temple folding.
- Premium Cellulose Acetate Construction: High-density acetate is tumble-polished to achieve a glossy finish, ensuring structural durability and skin-friendly wear.
- Polarized TAC Lens Technology: Fitted with high-clarity TAC lenses that block 100% of harmful UVA/UVB rays, glare, and reflections while delivering sharp visual contrast.
- Sculpted Ergonomic Nose Bridge: Smooth, integrated keyhole nose contours distribute frame weight evenly across the nasal bridge for pressure-free, non-slip comfort.
