The CATO sunglasses feature a sharp rectangular silhouette defined by clean lines and a structured, precision-cut profile. The frame is crafted in bold black that brings depth and dimension to the design, highlighting the strong angles and slim proportions. Designed with a refined, low-profile shape, the frame sits neatly along the face, creating a streamlined appearance without excess bulk. The black acetate finish adds subtle warmth and softness while still maintaining a polished, high-contrast edge around the eyes. The smoke lenses complement the frame with a cohesive tonal finish, providing a balanced tint that enhances visual comfort in bright light while maintaining natural colour perception.
