The neutral one. A grey lens dims everything evenly and changes colours least, which makes it the pair to reach for in flat bright sun and, of the five, the one for behind the wheel.

Why this tint

Grey is the tint that does the least to what you are looking at. It takes the whole visible spectrum down together rather than favouring one end, so a red light stays red and a green sign stays green. If you only ever wear one of the five, wear this one.

A neutral grey attenuates the whole visible spectrum together rather than favouring one end of it, so colour relationships survive behind the lens better than with any other tint. That is why it is the default for bright open light and the one to pick when you need to judge a colour, a traffic light included.

Questions, answered

Is the T01 Grey 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 Grey for?

Flat bright sun, driving, everyday. Dims everything evenly and changes colours least. The neutral choice, and of the five the one to reach for behind the wheel.

What size is the T01 Grey?

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 grey tint, the same from both sides.
