Cat writes: GUNNAR Optiks try pretty hard. They use capitalization and deliberate misspelling more recklessly than an internet troll. Additionally, GUNNARs (capitalization required) make a lot of bold, eye-related claims from creating a micro-climate to curing the world of DEF (Digital Eye Fatigue) and CVS (Computer Vision Syndrome, not the drugstore). The materials assert that half of American adults and 90 percent of our kids are suffering with DEF and CVS, "eyestrain, blurred vision, dry and irritated eyes or headaches, caused by exposure to digital screens." With stats like that, it's time cancer took a backseat. After sifting through the press materials and generally self-important blarney, I'm left with hunting glasses for nerds - but that's not a bad thing.
