Yun Seongsu

Yun Seongsu is the Seoul outpost of Yun, a Korean eyewear brand with an origin story as unique as its frames. Founded in Berlin in 2015, Yun was born from the intersection of two design cultures: the no-nonsense precision of German engineering and the aesthetic refinement of Korean design sensibility. The result is eyewear that feels both technically impeccable and effortlessly stylish.

The brand's slogan, 'Expansion of Vision,' captures its dual mission: expanding what you can see (through quality optics) and expanding how you see yourself (through design that enhances your look). It's a philosophy that has resonated strongly with design-conscious consumers across Asia and Europe.

The Seongsu store offers what few eyewear shops can: a complete end-to-end experience. Browse the full collection, try on frames at your leisure, consult with staff about your face shape and style preferences, and — here's the game-changer — get your lenses fitted and processed the same day. You can literally walk in needing glasses and walk out wearing a brand-new pair. For travelers, this eliminates the typical frustration of buying frames abroad but having to wait for lenses.
