Q: What's the difference between regular prescription lenses and frames and those that are "safety" rated?
A: In the United States, we have a government agency called OSHA that makes and enforces workplace safety rules and regulations. OSHA requires safety glasses in environments where eyes are at risk.
Safety glasses consist of a safety frame and safety lenses. A safety frame is sturdier than most "dress frames" and not easily bent or broken. Some have side shields, and some don't, depending on your specific job. Safety lenses are usually polycarbonate, which is basically jet windshield plastic that is very unlikely to break, even when shot with a bullet! Although OSHA regulations can seem like a real pain, they are really helpful in decreasing workplace eye injuries. In fact, those who do shop work at home should also use safety eyewear.
