Low Light Tint is great for cycling to work when you can't be sure you're not riding in the dark. It's bright enough not to cause vision problems in the morning after sunset or sunrise, although clear light is best for total darkness. This seems to improve color and contrast. It is still 100% UV and partially blocks light transmission.
