Great design to more people
The standard sizing system within eyewear never made any sense to us.
Why aren't there more sizes than one or two for a classic eyewear style? And why can't kids have the same styles as adults, just as with a pair of jeans or a white t-shirt?
BIOBIO is a lot about sustainability, but offering great designs to more people is equally important to us. This is why we create designs for all sizes.
