Introducing the Saint Laurent SL 645/F eyeglasses, a refined unisex design that harmonises architectural lines with modern luxury. The rectangle eyeglasses silhouette delivers balanced proportion, ideal for daily wear and enduring style. Crafted in Italy, this pair features a robust front in the RAC material and a timeless Black finish on both the frame front and temples, complemented by transparent lenses that offer clean, versatile vision. Available across colourways Beige, Black, Green and Havana, and sized at 55 mm, they are engineered to fit a range of face shapes with quiet confidence.

The craftsmanship speaks softly of premium heritage. Each component is selected for durability and comfort, while the understated detailing ensures this frame remains at home in both professional environments and refined evenings. The Italy-made production speaks to a tradition of luxury eyewear, pairing long-lasting performance with everyday elegance.

On Ardor Eyewear, you can choose the SL 645/F frame alone or pair it with prescription lenses. We offer prescription-ready customization on the product page, and we will fit your personalized lenses and ship the finished glasses to you in 8–12 days, with authentic packaging and full manufacturer assurance.

Face shape guidance: the rectangular geometry of SL 645/F flatters round and oval faces for balance while adapting gracefully to heart-shaped or angular (square) profiles when proportion is considered. If your features are softly curved, this frame adds structure without overpowering your look.

Elevate your daily appearance with a frame that signals quiet confidence and modern luxury. The SL 645/F pairs easily with a contemporary professional wardrobe or a high-fashion, city-living lifestyle, making it a versatile choice for those who value authenticity, comfort and timeless design.
