Smarten up your look with Ray-Ban RX6437 prescription eyeglasses. The silhouette provides a classic, collegiate look that suits men with heart, round, diamond, or oval faces. Thin, full-rim metal frames offer a lighter take on angular eyewear without sacrificing durability. The narrow temples taper off to a an even thinner tip that's rubber-coated to reduce slipping. Adjustable nose pads ensure a snug fit whether you are poring over blueprints or crunching code.
