Give me weather. Give me a sky doing something. Because the honest truth about sunglasses is that most people buy them for a cloudless day, and a cloudless day is the easy problem. The hard problem is the day that changes: bright, then a squall coming over the ridge, then that flat white light after rain when everything shines and nothing has a shadow.
The Maui Jim Polarized Stingray is a wrap-frame polarized pair, and polarization is exactly the technology for that miserable in-between light. Here is why. Light reflecting off a flat wet surface comes back with its waves aligned along one plane — that is glare, and it is worst not in bright sun but on wet ground under a bright overcast.
A polarized lens is a filter set across that plane. The rest does.
The aligned light simply does not get through.
The wrap shape is the other half of it. A curved frame closes off the gap at the side of your head, which is precisely where weather-light gets in — low sun under a cloud edge comes at you almost horizontally, and a flat lens does nothing about it whatsoever.
Now, I have to be straight with you: I could not get the frame dimensions, the base curve or the lens material for this model out of anybody. The manufacturer's own data would not load, not once, and I tried until it became embarrassing. I am not going to invent a measurement. Go and put them on.
Faces differ more than frames do.
Pyatigorsk is where I would take these and I would go in an unsettled week, deliberately. The Aeolian Harp stands on a spur of Mashuk — a stone pavilion from 1828 that was built to hold a wind-played instrument, so the weather itself made the music. On a clear day you can see Elbrus from up there, and on most days you cannot, and that gamble is exactly the point of going.
Down at Proval there is a turquoise sulphur lake eleven metres deep inside the mountain, reached through a bored tunnel.
You will wear these everywhere from an evening clinic back home to that spur when the cloud is deciding, and by the way, they are perfect for the coloured Warsaw glass of the Lermontov Gallery, which does extraordinary things to light and is worth an hour on its own.
The hard problem is not bright sun. It is the flat white light after rain, when everything shines and nothing has a shadow.
