Ray-Ban RB5419D 2000 is a sophisticated unisex optical frame designed with a modern square silhouette. Crafted from acetate in a polished black finish, the frame offers a bold yet clean appearance that works well with a variety of face shapes and personal styles. Its 54-18-145 sizing provides a balanced medium-to-wide fit, while the full-rim construction gives the frame a stable and durable feel. The frame can be fitted with prescription, single-vision, bifocal, or progressive lenses, subject to the prescription and lens laboratory requirements.
