Many years ago when I was polishing the ends of a plastic rod to verify Faraday's Effect, the last polish I used was tooth paste. Might that work here?
Also, the old suggestion for scratched watches was to coat them with clear nail polish.
If all else fails except getting a new phone, I'd probably give one or both of these a try.

Hi --
I have a cell phone with a built-in camera. I rarely use the camera,
but when I want to use it I really want to use it, and I want it to
work. Alas the thing has lived in a pocket so long that the lens is
scratched. The scratches are numerous but not deep.
I know from putting a thin film of liquid on it that the scratches
are the dominant problem. I used ethanol because it goes on thin
and flat ... but it is not a permanent fix.
The relevant surface of the lens is supposed to be planar; the
curved surface of the lens is safe inside the device.
Options include
-- buffing out the scratches, in which case the question is what
tools and techniques to use, and what to use for buffing compound.
Mother's Plastic Polish?
-- filling the scratches, in which case the question is what to
use for a filler. Lemon Pledge?
-- buying a new phone.
-- perhaps some less-obvious options????
I found a commercial filler, but the reviews indicate that it is
worse than nothing:

Any suggestions? I'm willing to experiment a little with anything
that won't make the situation worse.
