Vada Siren sunglasses redefine eye-catching style. Inspired by ancient Greek vessels, these sunglasses showcase gemstone-inspired shapes. Gold-tone details and unique rivets allow for the addition of VADA's gold chain retainers, fusing eyewear and jewelry. Handmade in Japan from custom, organic cellulose acetate, the unisex fit features a diamond-shaped frame with a double wing-tip temple design. These frames are prescription-ready, and the lenses can be swapped out by any optician.
