Bolle Cobra Safety Glasses with Black Frame and Contrast Anti-fog LensDanMarch 8, 2012So I use these goggles for two purposes: racquetball and chemistry. As sport safety glasses (for which I will say they are not designed) they are exceptional. They fog up a little, but they will unfog if taken off for any period of time. Unfortunately, the Contrast Coating actually makes telling color differences a little difficult. When I do titrations in chemistry I need to be able to see the first time a substance exhibits the slightest change in color. These make everything seem a little yellow and make it difficult. They're still great glasses though!
