Many sunglasses have a familiar silhouette, so it often comes down to materials and craftsmanship to differentiate one pair from the next. Crafted by hand in Japan from ultra-lightweight titanium, Barton Perreira's Javelin Sun shades are a refined take on a navigator style. The lenses are made from durable CR-39 with an anti-reflective coating, while the frames have the brand's signature crosshatch detailing at the temples.
