Feeling the bright sun in your eyes while driving is a recipe for disaster. With the VisorTwin Glare-Blocking Car Visor, you get some respite while keeping your eyes on the road. Even with sunglasses, the sun can prove to be far too intense and it obstructs your view. And, your car’s built-in visor doesn’t just block the sun, but it blocks everything else, too, limiting your field of view. VisorTwin solves all these problems instantly and works both horizontally and vertically. Installing easily onto your built-in visor, it allows you to block both side and windshield glare. In addition, VisorTwin is totally transparent yet offers effective blocking from the sun. This means you can still totally see the road, just without the glare in your eyes. In fact, it blocks 92% of UVA light. It’s like an extra set of UV 400 sunglasses. If you need, you can also extend the length of your car’s visor with VisorTwin. Also working on the passenger side as it swings a full 180°, VisorTwin stows out of sight when it’s not in use.
