Semantics is important when you're trying to change the definition of a word that is rigorously defined
I'm not changing the meaning of "lens". First-of-all, I don't have that kind of authority. Second-of-all, the bumpy plastic is clearly being used as a lens.
The bumpy plastic is used to focus light onto the sensor array in a novel way that allows the resulting sensor image to be used to construct 2D and 3D images. A lens focuses or disperses light, normally to form an image. That's what is happening here in this device. Just because the lens shape is irregular, unplanned, and not a standard one you'd find in a camera shop doesn't mean it's not a lens.
reference material that is from something a bit more rigorous than ylighting's webpage
That was just one of many examples of references to "diffuser lens". Feel free to do some googling.
