Collection: Persol Women's Square Sunglasses

Our Persol womens square sunglasses collection gathers the boldest, most architectural silhouettes in the Persol women's line-up, pairing the sharp geometry of a squared frame with the unmistakable Italian craftsmanship that has defined the house since 1917. If you want sunglasses that frame the face with confidence, add structure to softer features and carry a story of genuine Turin heritage, this is where to start. At Ardor Eyewear you are buying from an authorised UK stockist, so every pair is 100% authentic, complete with Persol packaging, case and manufacturer documentation.

Why Persol womens square sunglasses stand apart

Persol has never chased trends; it has quietly perfected details that other makers overlook. The square shape is one of the brand's most flattering registers for women, because clean horizontal lines and defined corners create balance against rounded cheekbones, soft jawlines and heart-shaped faces. Where a round frame echoes the curves of the face, a square Persol introduces contrast, and that contrast is what reads as polished and deliberate. Across this edit you will find models such as the PO3292S, PO3348S, PO3375S and PO3355S, alongside the graceful PO3199S and the characterful PO3333S "Elio", each interpreting the square idea a little differently, from soft-cornered squarish ovals to crisp, generous panto-square hybrids.

What unites them is Persol's engineering. The famous Meflecto system uses flexible cylinders in the temple arms so the stems gently grip the head without pinching, a genuine comfort advantage over long days. The Supreme Arrow, the sculpted metal hinge that arcs across the temple, is both a decorative signature and a functional reinforcement. And the lenses are frequently cut from thick, optically corrected crystal (mineral glass) that resists scratching and delivers exceptionally clean, distortion-free vision. These are the quiet luxuries that make a Persol feel different in the hand.

Choosing the right square frame for your face

Because a square frame is assertive, fit matters. A few simple guidelines help you choose well:

• Round or oval faces gain the most from square Persols; the angular corners add definition and a hint of drama.
• Heart-shaped faces suit a square frame that is slightly wider at the top, which balances a narrower chin.
• Square or angular faces can still wear the shape beautifully by choosing a softer-cornered squarish design, such as many of the acetate PO3300-series pieces, rather than a hard-edged rectangle.
• Check the lens width and bridge printed on the temple; a 51–54mm eye size tends to read as a refined medium fit for most women, while wider sizes make a stronger fashion statement.

If you love the squared look but want to browse beyond a single brand, our wider square-shape sunglasses edit and our curated women's sunglasses hub are natural next stops. To see the full Persol range across every shape, visit the main Persol sunglasses collection.

Materials, colour and lens options

Persol works primarily in rich cellulose acetate, hand-polished to a deep lustre that ages gracefully. Expect the house's signature Havana tortoiseshell in warm honey, caramel and coffee tones, alongside classic gloss black, smoke, and occasional translucent and crystal finishes that flatter cooler complexions. Metal-accented models pair acetate fronts with the Supreme Arrow hinge for a jewellery-like quality.

On the lenses, you will find solid tints, gradients that fade from darker at the top to lighter at the base, and polarised options that cut glare from roads, water and glass. Every pair offers full UV400 protection, shielding your eyes from UVA and UVB rays. If you prefer glare reduction for driving or coastal light, explore our dedicated polarised sunglasses range. And because Persol crystal lenses can often be glazed to your prescription, these frames can double as prescription sunglasses; see our prescription sunglasses service for details.

Styling your square Persols

A squared frame is inherently versatile. In tortoiseshell it warms neutral tailoring, linen and knitwear for an effortless off-duty look; in black it sharpens evening dressing and monochrome outfits. The PO3333S "Elio" and the PO3199S lean elegant and understated, ideal for city days and the office commute, while a wider PO3348S or PO3375S makes a stronger statement for holidays, festivals and weekend brunches. Because the palette skews warm and classic, these are sunglasses you will reach for season after season rather than retiring next summer.

Caring for your Persol sunglasses

To keep acetate glossy and lenses pristine, clean with the supplied microfibre cloth and a spot of lukewarm water; avoid alcohol wipes, which can dull acetate over time. Store the frames in their Persol case when not worn, and keep them off the top of your head, which stretches the temples. Have the Meflecto arms adjusted by an optician if the fit loosens; a quick professional tweak restores that trademark secure, comfortable hold.

Frequently asked questions

Are square sunglasses flattering for women?

Very much so, especially on round, oval and heart-shaped faces, where the angular corners add welcome structure and contrast. If your own face is quite angular, choose a softer-cornered square for a more harmonious balance.

Are these Persol sunglasses genuine?

Yes. Ardor Eyewear is an authorised UK stockist, and every pair is 100% authentic, supplied with official Persol case, cloth and documentation.

Can I have my prescription fitted to these frames?

Most Persol frames in this collection can be glazed with prescription lenses, including single vision, varifocal and tinted options. Visit our prescription sunglasses service to start an order.

Do they offer proper UV protection?

Yes. All sunglasses in this range provide full UV400 protection against UVA and UVB rays, and many are available with polarised lenses for extra glare control.

What size should I choose?

Look at the lens width on the temple arm. A 51–54mm eye size is a refined medium fit for most women; larger sizes create a bolder, more fashion-forward look.

How long does UK delivery take?

Non-prescription orders ship promptly with free UK delivery. Prescription sunglasses take around seven to ten working days for glazing before dispatch.

What is your returns policy?

We offer a 14-day returns policy on unworn frames in their original condition. Return postage is paid by the customer.
