Nano Vista Fanboy 3.0 NAO3171154SC Boys’ Rectangle Eyeglasses with Sun-Clip in Shiny Black

The Fanboy 3.0 NAO3171154SC 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. This model features a precision-engineered sun-clip that attaches directly to the optical frame, instantly converting prescription eyewear to UV-protective sunwear — ideal for active children who move between indoor and outdoor environments throughout the day. The patented 52° hinge that NanoVista developed for the Siliflex™ frame system allows a full 180° rotation without breakage — a specification that communicates, in engineering terms, exactly what the brand means when it calls its frames virtually indestructible. No metal parts, no screws to lose, no hinges to snap. Just the Siliflex™ material returning to its original shape whatever a child does to it, and the 3-in-1 fastening system adapting to whatever the day requires.

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.
