Nano Vista Loot 3.0 NAO3420348 Boys’ Square Eyeglasses in Black/Green

The Loot 3.0 NAO3420348 is a boys’ square 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. Parents trust NanoVista because it consistently delivers on its core promise: glasses that survive childhood. The Siliflex™ material — patented, BPA-free, heat-moldable, and completely metal-free — is the technical foundation of that promise. The 52° hinge that provides 180° rotation without breakage is its mechanical expression. The 3-in-1 fastening system is its practical application to daily life. And the brand’s position as Spain’s number-one children’s optical brand, endorsed by paediatricians and ophthalmologists worldwide, is its market validation. These are glasses built to last.

The Loot 3.0 is a bold square boys’ collection — offering NanoVista’s most energetic bicolour combinations in a square silhouette with the brand’s characteristic Siliflex™ durability and complete absence of metal parts. The square silhouette adds angular definition to round and oval face shapes, providing strong geometric structure that suits a wide range of children’s face geometries. Available in multiple sizes so the right fit can be maintained as your child grows.
