About Ray-Ban RX5421 8423
Ray-Ban RX5421 in colour code 8423 keeps things clean and squared-off, with a rectangular full-rim silhouette that sits comfortably in everyday rotation. The plastic frame is finished in a tortoiseshell blend with tortoise red tones, giving the classic pattern a warmer, more current edge without drifting into novelty. Clear demo lenses keep the look crisp out of the box, while the unisex styling and straightforward lines make it an easy match for round, heart, and oval face shapes.
This model is RX-ready and built for real-world prescriptions, supporting single vision or progressive/multifocal options. It suits PD ranges from 60 to 84, with prescription compatibility from -5.00 to +4.25 and cylinder ranges from -6.00 to +6.00, so you can tailor the finished pair to how you actually see, not just how the frame photographs.
