I just got a pair of Gunnars at Play N Trade and so far they have worked really well. I get headaches a lot especially since I work on a computer from 9-5 then come home and play halo for another 2-6 hours depending on the day of the week, so my eyes get a lot of stress put on them so far the Gunnars have softened the light from the monitors I use and help me stop squinting and straining my eyes.
