I wear these for my morning commute in the dark, my afternoon ride in the sun and when mountain biking.

The mirrored coating reduces glare, they are clear enough to ride before the sun comes up, and they take the harshness out of the afternoon sun without changing the color of objects.
I used to sell a lot of z87 glasses and these were my number one seller. They don't look the coolest, but they work the best.
