We're not sure exactly why you'd need to be doing activities that require safety glasses without adequate lighting, but just in case you're the type of person who operates power tools in the middle of the woods at midnight, you'll want these Dual LED Safety Glasses ($20). They feature two LED lights powered by two CR2032 batteries, clear lenses that offer a 180 optically correct viewing area, and 99.9% UV protection, because you're so likely to wear these out in the sun.
