Description
The Ray-Ban RB3637 9196/Y0 (Legend Gold) 50-21 are modern unisex sunglasses from the New Round collection, designed with a focus on minimalist gold metal styling, lightweight construction, and fashion-forward round/phantos shape design. The RB3637 “New Round” features a soft phantos/rounded silhouette, blending circular and slightly flattened edges for a refined modern retro look. It is part of Ray-Ban’s updated round-metal family, designed to feel lighter and more contemporary than classic round frames.
The “9196/Y0” color code (Legend Gold) corresponds to:
- Polished gold metal frame
- Silver/green or gold-toned lens variants depending on region (often polarized in this configuration)
The size is:
- 50 mm lens width
