Round in shape with a metal build across both the front and the temples, the SR3447 comes in a 50mm eye size and 145mm temple length, matching the rest of the line's proportions. The polycarbonate lens is UV400-rated, and this frame is available with G15 green, brown, grey gradient, brown gradient, or black mirror lenses depending on how much tint or reflection you want.

Black keeps the round metal frame as understated as this style gets, a uniform dark coat with no warm or cool metallic undertone competing for attention. It's the pick for anyone who wants the round shape itself, the way it sits on the face and opens up peripheral vision compared with a squarer front, without the frame color becoming part of the look.

Frequently asked questions

Is this just a Ray-Ban or Oakley shape with a different label on it?

The SR3447 is an independently designed SR frame — its Round shape takes inspiration from popular styles, but it isn't a replica of any Ray-Ban or Oakley model, and it isn't affiliated with either brand.

What size is this frame, and how do I know it'll fit my face?

The SR3447 has a 145mm temple length in a Round shape; if your current glasses feel right on a similarly sized frame, this one should sit comparably across the bridge and behind the ears.

What material is the frame made from, and how sturdy is it?

The SR3447 is built in durable acetate or metal depending on the Round style, designed to hold up to daily glazing, adjustment, and wear at the optician's the same way any other everyday frame would.

Is there a warranty if the hinge or frame breaks down the line?

Every SR frame, including the SR3447, is covered by a 3-year warranty against manufacturing defects, and at €49.00 for the frame alone plus free worldwide shipping, it's an affordable base for any prescription.
