The Ray-Ban RB4378F brings a softer take to the classic square silhouette. Crafted from acetate in a rich tortoiseshell finish, the frame features a squoval shape that balances a defined upper line with gently rounded corners and a smooth, curved lower edge. The slightly oversized front gives it a confident presence, while the softened contours keep the look relaxed and easy to wear.
The tortoiseshell pattern combines deep brown and near-black tones with subtle amber highlights, adding depth and variation to the frame. Brown gradient lenses complement the warm colour palette, transitioning from a deeper shade at the top to a lighter tone towards the bottom.
Finished with full-rim construction and 100% UV protection, the RB4378F is a versatile everyday style with a distinctive, understated character.
