Ideas

Ways to
use them

General ideas to get you started.

1. Road and mountain rides
Keep the same glasses on as the light changes.
2. Dawn and dusk runs
Nearly clear at first light, gray once the sun is up.
3. Changing light on trails
From tree cover to open sun without switching glasses.
4. Outdoor sports
A light half-frame for any session outside.

Good to know. The lens is photochromic, not polarized. Most car windshields block the light that triggers it, so the lens may stay light inside a car.
