I need to an eyeglasses frame...its brand is Nascar 670, brown, size 49-18.?

I had two pair of glasses, one with photo gray and able to wear indoors. The other are sunglasses (permanent dark). I lost my sunglasses and because I hardly ever wore my others I had new lenses made and put them into the regular frames...Now I am working and need this frame to put the regular lenses in..any help as in where I could get them or where to search would be soo appreciated! ty ty ty
