Collection: Persol Unisex Square Glasses

The Persol unisex square glasses collection is built for anyone who believes a great frame should not be filed under "his" or "hers" — just well made, well proportioned and genuinely comfortable. Drawing on Persol's Turin heritage since 1917, this edit of 29 square and squared optical frames spans neutral proportions and versatile colourways that work equally well on a broad or a finer face. Priced from roughly £165 to £250 and supplied as an authorised stockist, every pair is authentic Persol, ready to be glazed to your prescription here in the UK.

What makes a frame truly unisex

Unisex eyewear is not about stripping out personality — it is about balanced geometry. A square Persol frame earns its unisex status through medium proportions, a symmetrical top line, restrained temple width and colourways that read as classic rather than gendered. The square shape itself is inherently democratic: its clean corners and defined brow line flatter a wide spectrum of faces, which is precisely why couples, friends and family members so often find themselves reaching for the same styles. Frames such as the PO3359V Jacques, the PO3375V and the keyhole-bridge PO0204V demonstrate this beautifully, with silhouettes that sit as naturally on a man as on a woman.

Choosing from a shared Persol unisex square glasses range also makes life simpler. Rather than second-guessing which category a frame belongs to, you can focus on what actually matters: fit, colour and how the glasses make you feel when you catch your reflection.

Persol craftsmanship, engineered to be felt

Persol's reputation rests on details you notice with your face before your eyes. The Meflecto system — flexible cylinders set into the temple arms — lets the sides flex outward to match the width of your head, so the frame grips gently and evenly instead of pinching. The Supreme Arrow hinge, that signature silver arrow tracking along the temple, was first devised for durability and remains the brand's authenticity signature to this day. And Persol's long history of cylindrical crystal lens-making underpins an ongoing obsession with optical precision that carries into the way each acetate front is milled and polished.

Together these features explain why Persol is a favourite among people who wear glasses all day. A unisex square frame from this collection is not just a shape you like the look of; it is a piece of Italian engineering designed to stay comfortable from the first coffee to the last email.

Materials: acetate and metal

You will find two broad material families here. Hand-polished acetate frames offer depth and warmth of colour — think Havana tortoiseshell, translucent smoke, honey and solid black — in a substance that feels pleasant against the skin and can be fine-tuned by your optician. Metal and combination frames provide a lighter, more understated profile with slim rims and delicate arms, ideal for a minimal look or a lower-profile fit. Both are built to Persol's exacting Italian standards, and both take prescription lenses without compromise.

Getting the fit right

Because this is a unisex collection, sizing is your most useful compass. Inside each temple you will find three measurements — lens width, bridge width and temple length (for example 53-19-145). If you already own glasses that fit comfortably, matching those figures is the fastest route to a great fit. As a rough guide:

• A lens width of 50–52mm suits medium faces and reads as a balanced, classic square.
• 53mm and up gives a bolder, more contemporary presence and suits broader features.
• A wider bridge (19–21mm) generally sits better on lower or broader nose bridges, while a narrower bridge suits finer profiles.

Face shape matters too. Square frames add welcome structure to round and oval faces, and softly rounded-square models keep angular faces looking harmonious rather than severe.

Styling square frames, any wardrobe

One of the joys of a unisex square frame is how easily it slots into any personal style. A tortoiseshell acetate feels relaxed and creative with casual knitwear, denim or a linen shirt. A sharp black square frame injects instant polish into workwear and tailoring, projecting quiet confidence in meetings. Smoky-grey and gunmetal tones sit effortlessly within a neutral, minimalist wardrobe. Because Persol frames are designed to be timeless rather than loud, they become a dependable everyday signature rather than a fleeting trend — and being unisex, they translate across a whole household's worth of style.
