1. Lens Category

Lens category: Lens ranges from 0 (the lightest lens) to 4 (the darkest lens).

The brighter the outdoor light, the more glare you get, and the darker the lens should be.

Conversely, the darker the sky, the lighter the lens should get to allow proper vision.

For cycling and running, it is recommended to choose lenses depending on the sunshine intensity.
