content: I do construction safety for a living, and like to try out different types of safety gear for comfort and function. Most inexpensive safety glasses scratch easily, and quickly become so fogged that folks stop wearing them, defeating the purpose. These glasses I've already dropped onto hard, abrasive surfaces many times, with very little damage. The plastic frame is comfortable, and the lenses give good vision even on bright, glaring sunny days (and, surprisingly, indoors). I actually like them better than some of the more expensive safety glasses around.For the price, well worth it, even with the inevitable jokes that you look like a bug eyed monster (construction site humor).
