Brown
Polarised · UV protection · 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 it does to the scene
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.

What is a brown lens for?
Cuts more blue than a grey does, which lifts apparent contrast and makes edges and distance easier to read. 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.
Is it polarised?
Yes. Every lens in this range carries a polarising filter, which removes the horizontally polarised glare that comes off water, roads and glass. The tint and the filter are two separate things doing two separate jobs.
Is this the darkest option?
We have not measured the transmission of any of the five, so we are not going to rank them by a number we do not have. What we can say is what each is built for: grey for flat bright sun, driving, everyday; brown for variable light, hiking, judging distance; dark blue mirror for open water, midday sun; ice blue mirror for water, snow, high glare; red mirror for patchy light, cycling, ball sports.
