When fake Oakleys first became a thing, I remember people on STW saying that it was actually very hard to make polycarbonate lenses that didn't filter out UV - any truth in that?
yes - its inherent in the material, providing they are using polycarbonate (which they are likely to do as its cheap)
The main differences are likely to be in the optical quality - ie distortion/flare etc.
