Introducing the Ray-Ban RB3720, a distinguished expression of timeless design. From its square silhouette to the precision of a full rim metal frame, this pair embodies the refined ease that defines premium eyewear. Crafted for versatility, the RB3720 is a unisex style that complements city silhouettes and quiet moments of reflection alike. As sunglasses, the RB3720 balances function and form. As the official stockist of Ray-Ban, Ardor Eyewear guarantees authentic craftsmanship, pristine manufacturer packaging, and a seamless shopping experience across online orders and fast delivery.
The frame presents a metal front paired with crystal lenses, delivering clarity and resilience. The classic square silhouette sits at a 55 mm width with a height of 48 mm, a balanced proportion that suits many faces. The lens base at 4.25 adds character, while the 20 mm bridge and 145 mm temples ensure a secure, all-day fit. Color options include Black On Gold and Green On Gunmetal, each finished to echo Ray-Ban's iconic luxury.
Designed to flatter a range of features, the RB3720 is well suited for face shapes like round, oval, long and narrow. The adjustable nosepads provide gentle, personalized comfort, letting you dial in a precise fit whether you wear these with distance or reading lenses. The bridge size of 20 mm and temple length of 145 mm contribute to a secure, all-day wear that respects your day’s pace and style demands.
Every pair ships with Ardor Eyewear's commitment to premium service: authentic Ray-Ban packaging, timely dispatch, and transparent tracking.
