I have a Toyota Avalon head-up display on my windshield that shows my speed, speed limit, set speed and other information right on the windshield where I can see the road while driving. Because this is essentially a reflection of information from the upper dash bouncing off the windshield, I can't use regular polarized sunglasses. This particular non-polarized one works great because it protects my eyes from sunlight without erasing the "heads up" information reflected on the windshield! If you have them you know what I mean and these goggles double as sunglasses and keep my eyes on the road and see vital speed information. It was really hard to find glasses that weren't polarized, and despite what "Robbie" said, they aren't polarized. It had the wrong item.
