■Brand concept
Something that illuminates your humanity. Not just a decoration, but something that becomes a part of you. Something that will become your symbol, your keepsake, your legacy.
Eyewear brand Yin Year aims to explore the possibilities of glasses as a tool to the fullest extent, to illuminate humanity, to make glasses a part of you rather than just a decoration, and to give you an identity that goes beyond who you are without glasses.
