Black & Bleu Plant Based Polarized Square Frame Sunglasses

Black & Bleu pairs a gloss black bio-acetate frame with light blue TAC polarized lenses, and the effect starts the moment you put them on. The world takes on a cool, clean cast, edges sharpen, and the light around you settles into something calmer and more composed.

The bold square silhouette gives the blue room to make its statement. Black keeps the frame grounded while the lens color draws attention straight to the eyes, a pairing that reads confident from across the room.

Why Blue

Blue has long been tied to calm, clarity, and focus. It is the color of open sky and still water, and the tint people reach for when they want to feel collected. Black & Bleu puts that intention directly in your line of sight, giving the day a cooler, steadier tone so you move through it with a clear head.

When to Wear It

Bright afternoons, waterfront days, and city streets in full sun. The polarized lens cuts glare off water, glass, and pavement, and the blue tint keeps everything feeling cool when the heat is up.
