Black and gold rectangular glasses

Black rectangular sunglasses with graduated lenses

Across a room, a graduated tint behaves nothing like a flat one. The top band is darkest, just under the brow line, and that is the part anyone facing you registers; further down the lens clears and the eye stays readable. The practical result is that this front looks broader and more sheltering at a distance than it does in the hand, an effect a single solid tint would flatten straight away.

The gold panel, the dark tips and the plain bridge

Four photographs cover the pair from the front, from the side and from behind.

Why the pattern only turns up in side-on photographs

Straight on, the temples vanish behind the front and the gold never shows. It takes a three-quarter or profile angle for the panel to come into view, which is what makes it a private sort of detail: the people who notice it are standing beside you, not opposite. Useful to know before you look at which other pairs keep their pattern on the temple.

One caveat on pairing: gold jewellery tends to compete here rather than echo, so keep it thin, or borrow from the scarves and brooches on the next shelf instead. A single stud and a bare wrist leave the temple to do the talking, which is roughly what it was designed for.
