Nano Vista Fanboy 3.0 NAO3171554 Boys’ Rectangle Eyeglasses in Matte Black

The Fanboy 3.0 NAO3171554 is a boys’ rectangle frame from the NanoVista collection — built from Siliflex™, the brand’s patented virtually indestructible material, and designed for the real physical demands of active children’s lives. The NanoVista Siliflex™ system has been validated by the market and by the medical community simultaneously — Spain’s best-selling children’s optical brand and the most recommended by paediatric eye care professionals. This combination of commercial success and clinical endorsement reflects a product that genuinely does what it claims: withstands the physical demands of childhood, fits correctly on growing faces, contains no harmful materials, and delivers consistent prescription correction through continuous, comfortable wear.

The Fanboy 3.0 is a bold rectangular collection for boys — designed around the confident proportions and energetic colour combinations that NanoVista’s most enthusiastic young wearers reach for first. The rectangular silhouette provides clean horizontal definition that suits a wide range of children’s face shapes, adding the horizontal emphasis that flatters rounder facial geometries while providing a reliable, structured frame for prescription lenses. Available in multiple sizes to accommodate growing faces.
