Saint Laurent SL181LOULOU

SL181LOULOU: shape and build

The lens is held by a full rim all the way round each lens. The frame sits on a plain single bridge, and the nose rest is part of the frame. Our supplier lists the frame as acetate. 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. The frame is finished with acetate temples. The branding runs along the outside of the temple. Its signature is the heart-shaped frames. The colour code is 008, Saint Laurent's own name for this finish.

Reading the size

The size is 54-21-145: lens width, bridge width and temple length in millimetres. The lens width of 54 mm is medium for a sunglasses frame. The pair leaves the supplier exactly as packed by the maker, so a small fit adjustment, if needed, is an optician's job.

The grey gradient lenses

The lenses are grey gradient. Grey is the neutral tint: it dims light evenly without shifting colours. A gradient tint, darker at the top than at the bottom. Polarization and UV rating are not in the supplier's data for this pair, so neither is claimed here.

Same frame, other colourways

We also carry the SL181LOULOU as 002 (Red with grey lenses), 012 (Black/Grey Havana with grey lenses), 020 (Nude with brown lenses) and 027 (Transparent Nude with copper mirror lenses), the same frame in other finishes.
