When I bought these I thought to myself that for such a low price I would be getting a poor quality product, but when I received the pair I was actually really amazed. The plastic and rubber used in the frames is pretty high quality. The glass is actually scratch resistant, something that I totally wasn't expecting. I have had this pair for a few months now and it has barely got any scratches. If your work requires you to wear safety glasses I suggest that you definitely give these a try.
