Sunglasses in warm light

Maritime Optical Laboratory

Eyewear shaped by coastal light.

SeaSight began with a simple frustration: most sunglasses are either fashion props or sports gear. We wanted frames made for glare, motion, and long coastal days.

We work out of a small atelier in Cascais, just west of Lisbon. The light there does something unusual — it stays warm even when it's sharp — and it's shaped how we think about polarization, lens tint, and frame proportion.

Every piece is hand-finished in Italian acetate, fitted with mineral glass or polarized nylon lenses, and packaged in a refillable cork case. We release a small number of frames each season because that's all we can make properly.
