Q: So do you get an insert to put your prescription lenses in?

Yes and no. You likely cannot wear your own classes as the wrap (at least on my head) is pretty snug. But, it does come with a sort of "Pince-nez" which you can see separate on the image, and you can have your prescription custom made to fit that. I did not, and it would "probably work", except you are putting your expensive lenses into an inexpensive platform. You'd be better off with contacts (IMHO)
