My girlfriend got me a pair of Gunnar pipelines for Xmas and so far they have worked. They aren't quite as yellow tinted as the pictures suggest and they seem to be polarized slightly as well as having a slight magnification. Admittedly I felt like a complete toolbox for wearing them to a Forza 24 hour Enduro tournament but after 18 hours at the wheel I noticed how many people were rubbing their eyes at pit stops. I frankly believe my Gunnars won that tournament for me. If you stare at a screen for long periods of time and have the money to spend they do work for cutting down the glare as well as sharpening the color contrast. There are negatives to consider though, Like every one and their uncle will ask you if they work even if you are in the middle of a race and finger prints on the lenses become huge blurry spots.
