This SR4068 frame keeps the same square plastic build across front and temples, with a 50mm eye size and 140mm temple length matching the rest of the line. Lenses are UV400 polycarbonate, and the tint list for this style runs from everyday greens and browns to mirrored, gradient, and photochromic finishes, giving plenty of choice independent of the frame color.

The regular Havana colorway is a deeper, richer version of the tortoiseshell look than Light Havana, with darker amber and brown tones mottled together instead of a pale wash. It's a more traditional take on the pattern, with enough depth in the color to read as a warm neutral rather than standing out as a statement shade, which suits it to daily wear more than a look built around the frame color itself.

Frequently asked questions

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.

What if the frame doesn't suit my face once I see it in person?

You can try the SR4068 on and return it within 14 days if the Square shape or the 140mm fit isn't right for you, before you've had it glazed with lenses at your optician.

Are these prescription glasses, or do I need to add lenses separately?

The SR4068 ships as a complete frame only, ready for your optician to glaze with prescription lenses of your choice, or you can fit a clear CR39 lens yourself if you just need a non-prescription pair.

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.
