Why this tint
Blue is the wavelength that scatters most, in the air and inside your eye, and that scatter is the haze that flattens a landscape into one plane. Filtering it separates the near from the far. The trade is that the scene shifts warm, which is why brown is the choice when depth matters more than colour accuracy.
Blue light scatters more than the longer wavelengths do, both in the atmosphere and inside the eye, and that scatter is the haze that flattens a landscape. Removing some of it separates near from far. The scene shifts warm in exchange, which is the trade you accept when depth matters more than colour accuracy.

Questions, answered
Is the T01 Brown polarised?
Yes, and it carries UV protection. Every pair in this range does; the tint in front of the filter is the only thing that changes between them.
What light is the T01 Brown for?
Variable light, hiking, judging distance. Cuts more blue than a grey does, which lifts apparent contrast and makes edges and distance easier to read.
What size is the T01 Brown?
60▫15▫145: a 60mm lens, a 15mm bridge and 145mm temples, in a front measuring 140mm hinge to hinge, with a 50mm lens height. Those are the frame maker's published figures rather than ours, and the fit guide shows how to check them against your own face.
Is the mirror on the outside?
This pair is not mirrored. It is a plain brown tint, the same from both sides.
