Hi, sorry to hear about the scratches. I don't have any experience removing scratches from Rift lenses, but I do have experience using that PlastX product on optically-clear plastic windows. IMO, It is capable of better results than the person in that video achieved--the things I've used it on had no visible haze or swirls at all after I was done, even holding it at an angle to a bright light source.
The trick to using it is that the polishing compound in it gradually breaks down as you rub it in. It starts out fairly abrasive to remove scratches, but as you work the product the abrasives break down to a point that it becomes like a watery polish without any abrasive at all. If you've ever sanded something with progressively finer and finer sandpaper, it's the same concept, except it all happens within a single product. If you don't rub the PlastX long enough and/or don't use enough pressure, the compound doesn't break down like it's supposed to, so the swirls from the abrasives don't get buffed out like they should.
If you have an old CD or DVD you don't care about, I'd suggest practicing on that first to get the feel for it.
Start with a *very* small amount, and keep rubbing it with light pressure (I'd suggest using your fingertip and a high quality microfiber cloth). At first you will feel a noticeable friction from it, but as you keep rubbing it the friction will decrease (this is due to the abrasive breaking down). Keep rubbing until the PlastX breaks down to an almost watery consistency, and then keep rubbing some more to really buff the surface. Then wipe it away with a clean microfiber and check your results. Depending on how deep the scratches are, it can take several rounds of this.
Again, I can't make any promises about how well it'll work on the Rift lenses. In case you or anyone else decides to try it, I just wanted to add the info here on the PlastX product because it only works as well as the knowledge of the person using it. The person in the video above didn't buff long enough, and also, I doubt a cotton swab can apply enough pressure over the area to thoroughly break down the polishing compound to remove the remaining swirls. I think he would have gotten a much better result if he did it like I described above.
Also, don't, don't, don't, don't (did I say that enough?) use toothpaste. I've heard this suggested SO many times for polishing clear plastics and optics, and it is absolutely terrible advice. There is a huge difference between a product that is actually engineered for polishing plastics, and one that is made for cleaning teeth, and the cost difference between them isn't even that much. At best, it won't do anything except make your stuff smell minty. At worst, the abrasives in it will leave behind swirls that you'll have to use a proper plastic polish to remove anyway.

I don't think we ever got to the bottom of what plastic the fresnels are made out of.
Take care, whatever you do @MaxShadow09, and I'd only do it if those scratches really are a problem when using the Rift.
I think the size of the glasses may be more of a risk if they're smaller. My head is quite big and so my glasses are too. I think this means my head doesn't fit so far into the Rift so there always seems to be a reasonable gap between glasses and Rift lenses. The downside is that this makes it quite unconfirmable to wear without finding a solution, I don't get on well with contacts.
So anyway, you may want to try any polishing compound on a variety of plastics. Like CD (polycarbonate), CD case(polystyrene) and plastic lens cover on a car (poly-something else), that way you'll have covered all 3 likely plastics. But like I say, polishing would be a last resort if you have a big problem with those scratches and you're sure any vision issues aren't down to the usual god rays.
