Longchamp LO766S

What the LO766S is

What you get is a cat-eye front that lifts at the outer corners. The lens is held by a full rim all the way round each lens. Across the nose there is a saddle bridge that spreads the weight across the nose, 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. Acetate temples with a metal plaque at the hinge complete the frame. The branding runs along the outside of the temple. Look for the round metallic emblem on temple. The colour code is 300, Longchamp's own name for this finish.

The numbers on the temple

It measures 53-17-140, which is the lens width, then the bridge, then the temple length, all in millimetres. The lens width of 53 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.

What the lens does

Brown gradient lenses are fitted. A brown tint warms the view slightly and sharpens contrast. A gradient tint, darker at the top than at the bottom. Nothing in the supplier's data says these lenses are polarized or gives a UV rating, so we say neither.

What you get, and how it ships

You get a new pair in Longchamp's own box, with whatever case and cloth the brand supplies. Within the US it ships free, usually one to two business days after you order, and the tracking number is emailed to you. Unworn pairs in their packaging can be returned within 30 days of delivery, refund less the return label; defects, wrong items and transit damage are returned free when reported within 7 days.
