Discover the Ray-Ban RB4378, a refined addition to the modern woman’s eyewear. The silhouette is a crisp square inside a full rim, a timeless geometry that flatters a range of outfits—from tailoring to weekend silhouettes. The frame combines comfort and confidence, with injected front and slender temples that feel lightweight yet sturdy as you move through a busy day. This is authentic designer eyewear designed to endure, with a balance of form and function that makes every moment of wearing feel effortless.

Frame construction highlights everyday reliability. The front and temples are injected for comfortable, flexible wear, while the lenses are crafted from polycarbonate lenses for impact resistance and clear optical performance. The lens width is 54mm with a height of 47mm, a bridge of 16mm, and temples at 145mm, all harmonising for a clean, secure fit that accompanies you from morning meetings to city strolls.

Geofit High Bridge Fit ensures comfort for higher bridges and a wide range of face shapes, including Round, Oval, Long, and Narrow faces. The RB4378 is engineered to sit comfortably, with weight distributed evenly so you feel confident all day without constant readjustment.

Choose among a curated palette that complements every style, including Black, Black (601/8G) - Grey Gradient, Transparent, Transparent Grey, Havana, and Havana (710/80) - Dark Blue. Each option preserves the sleek, premium lines of the frame while offering variations to suit your mood or wardrobe.
