Japan

Heterodon is a substantial Japanese titanium framebuilt around a broad, rectangular aviator-inspired shape. The lenses are generous without feeling oversized, with softly rounded lower corners and a straighter upper line that gives the frame a strong, architectural presence.

Handcrafted in Fukui, Japan, Heterodon is defined by its exceptional metalwork. Fine linear engraving runs across the top bar and around the rims, while the layered brow construction and sculpted bridge add depth and structure to the front. The temples are slim but solid, carefully balanced to give the frame a reassuring sense of weight without becoming heavy on the face.

Small details continue through to the temple tips, with a lightning symbol on one side and Vasuma branding on the other. Available in black and gold, Heterodon is one of the most technically refined frames in the collection, with premium Japanese titanium, precise finishing, and a distinctly substantial feel.
