Let us start with who does the work, because that is always the interesting question. A sunglass lens does two jobs, and only one of them gets advertised. The obvious one is dimming. The other one — the real one — is filtering glare, and glare is not brightness.
Light bouncing off a flat surface comes back with its waves lined up in a single plane, and that aligned light is what makes you squint at wet asphalt, at a hard court at four in the afternoon, at the surface of a lake. It blocks the organised light and lets the rest through.
A polarized lens is a filter set against that plane.
The Maui Jim Polarized World Cup is a wrap frame doing exactly that, and the wrap matters, because the side of your head is where light gets in and a flat lens has simply never addressed it.
Two builds on the record, and both run the same lens: Marlin with Neutral Grey Polarized, and Matte Black Rubber with Neutral Grey Polarized. Note the rubber in that second name — that is a finish chosen so a frame stays put on a wet face, which is somebody on a factory floor solving a problem that no marketing department would ever have raised.
What I could not obtain, and will not fabricate, are the frame measurements, the base curve or the lens material. I would rather tell you that plainly than pass off a number somebody else guessed.
The manufacturer's own specification pages would not open for me, repeatedly.
Tiberias is where these belong, and I want to talk about the floor there. At Hamat Tiberias there is a fourth-century synagogue mosaic — a zodiac with Helios and his four horses set into it — and every single tessera in that floor was placed by hand, one at a time, by workers whose names are nowhere on it.
The same goes for the basalt walls of Daher el-Omar: eight metres high, twelve round towers, black stone quarried, hauled, dressed and stacked by people who got a day's pay and no plaque.
You will wear these everywhere from an evening clinic back home to that lakeshore at noon, where the glare comes up off the water hard enough to be a physical thing, and by the way, they are perfect for the walk along the walls at the end of the day.
