Collection: Persol Men's Square Glasses

Persol men's square glasses bring one of Italy's most storied eyewear houses to the shape that best flatters a masculine face — clean, structured squared frames built with the craftsmanship Persol has refined since 1917. There is a particular satisfaction in a well-made square frame: it adds definition, reads as confident and intelligent, and carries a Persol's unmistakable detailing without ever tipping into flashiness. This collection gathers prescription frames such as the PO3007V, PO3007VM, PO3189V, PO3375V, PO0204V and the PO3359V "Jacques", every one genuine and supplied as an authorised stockist, ready to be glazed with your prescription.

Persol heritage: Turin, 1917

You cannot talk about Persol men's square glasses without the history that makes them special. Founded in Turin in 1917, Persol built its name on eyewear designed for pilots and drivers who needed comfort and clarity for hours at a time. Two innovations became signatures. The first is the Meflecto system — the small set of interlocking cylinders visible in the temple arms — which lets the arms flex and adapt to the shape of your head for a comfortable, secure fit. The second is the Supreme Arrow, the distinctive silver arrow that runs along the hinge, a mark of authenticity and a piece of design that has appeared on Persol frames for decades. The brand's crystal lenses and hand-finished acetate rounded out a reputation for quality that made Persol a favourite of style icons — the 649 and 714 folding models, the latter worn famously by Steve McQueen, remain touchstones of Italian eyewear design.

That heritage carries straight into the square optical frames in this collection. The Meflecto arms are here, the Supreme Arrow detailing is here, and the acetate is worked with the depth of colour that only quality material and hand-polishing produce.

Why square frames suit men so well

Shape is doing real work in a pair of men's square glasses. A squared frame with clean, defined corners adds structure and contrast to softer, rounder and oval faces, which is why it is one of the most reliably flattering choices for men. The strong horizontal line broadens a narrow face and balances a fuller one, and the geometry reads as decisive and professional — ideal for the office and equally at home with casual dress. Persol's square designs, such as the PO3007V and PO3189V, keep the corners crisp but not harsh, so they look confident without being aggressive.

If your face is already quite angular, you can soften a square frame by choosing one with slightly rounded corners or a warmer acetate colour. If you would like to compare shapes before deciding, our square-shape sunglasses edit shows the silhouette in sun form, and the wider men's eyeglasses collection gathers other flattering options for men.

Materials: acetate and metal

Persol works its square frames primarily in hand-finished acetate, which gives rich tortoiseshell and deep black tones with genuine depth, plus comfort and easy adjustability. Some models combine acetate with metal detailing or use metal fronts for a lighter, more minimal look. Acetate suits those who want a little more presence and warmth; metal suits those who prefer barely-there weight. Both benefit from the Meflecto flexing arms that make Persol so comfortable over a long day. For a broader material comparison across brands, see our prescription glasses frames hub.

Prescription and lens options at Ardor

Every pair of Persol men's square glasses here can be glazed with your prescription. Choose single vision lenses for everyday distance or reading, or varifocals and bifocals if you need both near and far in one lens. You can add anti-reflective and scratch-resistant coatings, blue-light filtering for screen-heavy work, and photochromic lenses that darken outdoors and clear indoors. If you also want a sunglasses pair from the same house, our Persol sunglasses collection includes the iconic 649 and 714 alongside modern designs. Prescription orders are glazed in around 7–10 working days, with free UK delivery.

Choosing and fitting your Persol square frames

Start with the measurements printed inside the temple arm — lens width, bridge width and temple length — and compare them to a pair you already wear comfortably. A square frame should sit level, with the top edge near your brow line and the front roughly as wide as your face at its widest point. The Meflecto arms give Persol a naturally forgiving fit, and an optician can fine-tune the nose and temples further. If you are choosing colour, black is the versatile all-rounder, while havana and tortoiseshell add warmth and pair well with knitwear, denim and tailoring alike.

Caring for your Persol glasses

Clean the lenses with a microfibre cloth and lens spray rather than clothing, which can scratch coatings over time. Return the frame to its case when not in use, avoid resting it on top of your head where the arms can stretch, and keep it away from hot dashboards and windowsills, as prolonged heat can distort acetate. A little regular care keeps the acetate glossy, the Meflecto arms springy and the frame looking new for years.
