About Ray-Ban RX6421 2973

Clean, full-rim Wayfarer lines in a soft beige metal frame give the Ray-Ban RX6421 a crisp, modern look that stays easy to wear day after day. Built for prescription use, it supports a wide range of corrections (from -14.00 to +10.00, with cylinder up to ±6.00) and is suitable for progressive/multifocal lenses, so you can keep one consistent frame whether you’re updating distance, reading, or all-in-one vision. With a PD range of 58–82, it also covers a broad set of fitting needs when you’re ordering RX lenses online. Adjustable nose pads help fine-tune comfort and positioning, which is especially useful when you’re aiming for stable optics with stronger prescriptions or multifocals. The full-rim construction adds a defined outline around clear demo lenses, while the unisex shape suits a range of face shapes including heart, oval, and triangle. SmartBuyGlasses supplies genuine Ray-Ban frames and lets you add prescription lenses tailored to your needs, including multifocal options and available lens add-ons shown in the product details. Your order is backed by a 2-year warranty, 100-day returns, a Best Price Guarantee, and free shipping on orders over $80.
