PROTON was inspired by a type of architecture. A slit formed on the bridge is expressing division between the center and outside world. Special cutting was done to express the shade made possible by our master craftsmanship that only GYARD can deliver.

PRONTON are rather smaller sized sunglasses, but we think it has something to do with beautiful color variation in our architectual world.
