Description
The Ray-Ban RB3721 is a unisex square sunglass with a full rim construction, a metal front and metal temples, and adjustable nosepads. It is offered in a single 59mm lens width, shared across all four colour options, so the choice comes down to the finish you prefer.
Frame design and materials
The RB3721 has a square, full rim front in metal, paired with metal temples. The adjustable nosepads can be fine-tuned so the frame sits where you want it on the nose, and the overall design is intended as a unisex style.
Size and measurements
Every version of the RB3721 is offered with a 59mm lens width. The listed measurements are 59mm lenses, a 17mm bridge, 145mm temples and a 45mm lens height. Bridge, temple length and lens dimensions are separate measurements, so it is worth checking each one against a pair of sunglasses that already suits you. For the lens height, measure that same dimension on your existing pair rather than comparing it with the printed lens-width and bridge figures. If you would like help comparing, the Ardor Eyewear team is happy to assist.
Colour options
The RB3721 comes in four finishes: Black On Black, Black On Silver, Brown On Gunmetal and Black. Each finish is available with the 59mm lens width, so choose from the options shown on the page for the pairing you want.
Prescription lenses and delivery
Eligible prescription sun lenses are available for this model as an optional add-on; they are ordered in addition to the frame rather than included as standard. Standard non-prescription frames are delivered within 5-8 business days, and prescription orders can take a few additional business days while the lenses are made and fitted.
