Collection: Saint Laurent Medium Sunglasses

Saint Laurent medium sunglasses hit the proportion most people find easiest to wear: substantial enough to make a statement, balanced enough to suit the majority of faces. This collection brings together the label's mid-size shades — genuine, authorised-stockist frames including the SL 572, SL 567, the SL 596 Dune, the classic SL 500, the SL M115 Butterfly and the SL 633 Calista — each available to wear as-is or to be fitted with prescription lenses at Ardor Eyewear.

The case for medium Saint Laurent sunglasses

Medium frames are the quiet workhorses of any sunglasses wardrobe. They avoid the risk of looking too small and mean on one hand, or too oversized and costume-like on the other, landing instead on a versatile scale that photographs well and reads elegant in almost any setting. For a house like Saint Laurent — built on Yves Saint Laurent's legacy of sharp, wearable Parisian style — the mid-size category is where its design language is most fluent, spanning crisp rectangles, softened squares, gentle rounds and the feline SL M115 Butterfly.

This makes medium Saint Laurent sunglasses an ideal first designer purchase or a reliable everyday pair. They suit commuters, drivers, travellers and anyone who wants one dependable frame that transitions from a weekday errand to a weekend lunch without a second thought. Because the scale is forgiving, they also make a confident gift when you are unsure of someone's exact preferences.

How to choose your medium frame

With medium sunglasses, shape does most of the styling work. A squared front such as the SL 500 lends structure and a slightly masculine, timeless edge that suits rounder and heart-shaped faces. Softer rounds bring an artistic, retro warmth that flatters angular and square faces. The SL M115 Butterfly lifts and widens the upper frame for a glamorous, subtly cat-eye effect that women often gravitate towards. If you want to see how these silhouettes behave more broadly, our square-shape sunglasses and round-shape sunglasses collections are a helpful reference point.

Fit is straightforward at this size. Look for the three millimetre figures inside the temple — lens width, bridge width and temple length — and match them to each product page. Medium frames generally suit average face widths comfortably, but a well-judged bridge measurement is what stops them sliding or leaving marks. Many pairs include adjustable nose pads or keyhole bridges to fine-tune the balance.

On materials, Saint Laurent's medium shades come in both rich acetate and refined metal. Acetate offers deep tortoiseshell, gloss black and layered translucent colours with reassuring body; metal versions feel lighter and lend a sleeker, more understated look. Both carry full UV protection and the discreet YSL or Cassandre detailing the brand is known for.

Lenses and prescription options at Ardor

Most medium Saint Laurent frames can be glazed with prescription lenses, so you are not limited to ready-made tints. At Ardor we offer single-vision, varifocal, tinted, polarised and photochromic sun-lenses. Polarised lenses are especially worthwhile for driving and bright coastal light — see our polarised sunglasses range — while photochromic lenses adapt from clear to dark as the light changes. Those who need corrective shades should explore our full prescription sunglasses collection. Prescription glazing typically takes around 7–10 working days, with free UK delivery throughout.

Styling, occasions and frame care

Medium Saint Laurent sunglasses are effortlessly adaptable. A black acetate square anchors tailoring and city dressing; tortoiseshell rounds soften casual denim and knitwear; a butterfly silhouette elevates summer dresses and holiday looks. Their balanced size means they rarely clash with hats, hairstyles or bold accessories, which is exactly why they earn a permanent place in most collections.

Care is simple and pays off. Use both hands to put them on and remove them to protect the hinges, store them in the supplied case, and clean the lenses with a microfibre cloth and a little water rather than a dry shirt-tail, which can scratch coatings. Avoid leaving them on a hot dashboard, as sustained heat softens acetate and can loosen lenses. After a day at the coast, rinse off salt and sun cream to keep the finish sharp.

If you are still weighing up sizes, it helps to remember what medium delivers over its neighbours. Compared with small frames, medium Saint Laurent sunglasses give more coverage and a stronger presence without tipping into oversized drama; compared with large and extra large styles, they stay easy to wear for people who find big frames overwhelming or prone to slipping. That middle-ground versatility is precisely why medium frames tend to be the pair people reach for most often — the one that lives in the bag, the car and the holiday case. For a first designer investment, or as the reliable core of a growing sunglasses collection, a medium frame is the safest and most rewarding starting point, and the breadth of shapes here means you are unlikely to run out of options.

Every frame is authentic and sold as an authorised stockist, backed by free UK shipping and a 14-day returns policy (return postage is paid by the customer) — designer eyewear you can buy with total confidence.

Frequently asked questions

Will medium sunglasses suit my face shape?

Medium frames are the most universally flattering size. Match the shape to your features — angular frames for rounder faces, softer rounds for angular faces — and check the product-page measurements against a pair you already wear.

Can I have prescription lenses fitted?

Yes, most medium frames accept prescription lenses, including tinted, polarised and photochromic. Add your prescription at checkout and we will glaze them, usually within 7–10 working days.

Are these authentic Saint Laurent sunglasses?

Absolutely. As an authorised stockist, Ardor sells only genuine frames, each supplied with its official case and documentation.

What is the benefit of polarised lenses?

Polarised lenses cut glare from roads, water and shiny surfaces, improving clarity and comfort, particularly when driving or near the coast.

How much is delivery and what are the returns terms?

UK delivery is free. Returns are accepted within 14 days, with the customer covering return postage; prescription-glazed lenses may carry different terms.
