Nano Vista Birdie 3.0 NAO4020540 Girls’ Round Eyeglasses in Pink

The Birdie 3.0 NAO4020540 is a girls’ round 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 collection is designed for the full span of childhood — from the early years of the toddler and infant range through to the teenage collections that accommodate larger face geometries and more fashion-conscious preferences. The Siliflex™ material scales through this entire range, delivering the same durability, flexibility, and safety characteristics in every size. The 3-in-1 fastening system adapts to the activity level of each age group. And the brand’s commitment to continuous innovation — including the NanoFinder AirTag system — ensures that each generation of NanoVista frames is more capable than the last.

The Birdie 3.0 is designed for younger children — its compact proportions, gentle round silhouette, and cheerful colour palette make it one of the most popular NanoVista choices for the earliest years of prescription eyewear. The round silhouette provides a universally flattering circular geometry that works beautifully on most children’s face shapes, softening angular features and adding a contemporary, classic quality to the frame. Available in multiple sizes for precise fitting.
