France-based Ahlem Eyewear has been known for their minimalistic approach to the segment, but there’s a lot to appreciate. Their pieces are handmade in France and these ones done up in collaboration with Oklahoma’s Black Optical are unique yet wearable. Inspiration comes from structures designed by Oklahoman architect, Frank Wallace, with the collection featuring three different styles. Each comes in all-black with a flat, 18-karat gold mirror lens. Check out the styles in the gallery above and look for the Ahlem x Black Optical pieces to be available here.
