Focus on fit and silhouette: select a frame width that sits comfortably and consider whether the classic round look suits your face. Also choose a lens tint and ensure adequate UV protection for daily use.

Key factors are frame size and bridge width for comfort, lens color and coating, polarization status, and whether you want the classic RB3447 or the updated RB3447N variant.

Polarized lenses reduce glare in bright conditions and are useful for driving and outdoor activities; non-polarized lenses are lighter and typically simpler. Choose based on where you’ll wear them most.

Opt for RB3447 for the classic round silhouette; choose RB3447N if you want a newer frame variant, then compare lens options and measurements to fit your needs.
