I notice that they dont have the reflective sort of backing that the official lenses have so you can see horizontal lines from the display

The reflective backing on the official lenses have nothing to do with visibility. That reflective backing is for electromagnetic filtering only, it does not affect the way you can see into the front of the player.

The reason you can see the filament wires better is because, by using DarkStorm's lens, you have changed the color and the opacity of the lens. You didn't say which lens you got, but I'm guessing it was a Smoke or perhaps one of the lighter shades.

The filament wires glow a reddish shade, so dark blue or green shaded lenses will make the filaments basically invisible. But a smoke, red, or amber lens will make the filaments show up more clearly.
