Square in shape and molded entirely from plastic, the SR4068 comes in at a 50mm eye size with 140mm temples. Its polycarbonate lens is UV400-rated, and buyers can choose from a long list of tints for this frame, spanning solid colors, gradients, mirror coatings, and a photochromic lens that darkens in sunlight.

Light Havana sits at the paler end of the classic tortoiseshell coloring, a translucent, honey-toned brown with softer, less contrasted mottling than a standard havana pattern. It reads warmer and more casual than a solid black frame, and the lighter base tone tends to sit well against fair or golden skin tones without looking heavy on the face.

Frequently asked questions

Will my optician be able to fit lenses into this frame without issues?

Yes — the SR4068 uses a standard Square rim and groove that any local optician can glaze exactly like they would with any other frame, whether you need single vision, progressive, or reading lenses.

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

The SR4068 is built in durable acetate or metal depending on the Square 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 SR4068, 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.

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

The SR4068 has a 140mm temple length in a Square shape; if your current glasses feel right on a similarly sized frame, this one should sit comparably across the bridge and behind the ears.
