Saint Laurent SL181LOULOU

SL181LOULOU: shape and build

It has a full rim all the way round each lens. Across the nose there is a plain single bridge, and the nose rest is part of the frame. The frame material is acetate, per the supplier. Acetate is the plant-based plastic that most designer frames are cut and polished from sheet; it holds deep colour and an optician can re-adjust it with heat. It has acetate temples. The branding runs along the outside of the temple. The detail that stands out is the heart-shaped frame silhouette. Colour 027 is how Saint Laurent labels this version.

The numbers on the temple

It measures 54-21-145, which is the lens width, then the bridge, then the temple length, all in millimetres. At 54 mm across the lens this is a medium frame. If the fit needs a tweak once it arrives, any optician can adjust it; pairs ship exactly as the maker packed them.

Lens colour and finish

Lens colour: copper mirror. A brown tint warms the view slightly and sharpens contrast. A mirror coating that hides the eyes and throws glare back. Nothing in the supplier's data says these lenses are polarized or gives a UV rating, so we say neither.

Same frame, other colourways

The SL181LOULOU is also listed here as 002 (Red with grey lenses), 012 (Black/Grey Havana with grey lenses), 020 (Nude with brown lenses) and 008 (Black with grey gradient lenses). Shape and size are the same; only the finish changes.
