I've had good luck treating dull lenses as if they were dulled
lacquer (which technically is similar, being basically
plastic). Wet-sand the surface with 600 grit wet-or-dry sandpaper
(be prepared to expend some effort if you want good results) and
soapy water until the surface of the lens is uniformly "clean" and
satin-smooth, then assault it with rubbing/polishing compound (a car
buffer is a time saver), finish with a good rubdown with a reputable
brand car wax. If there's any hope of salvaging the lens at all,
this will do it.
I've seen a few lenses that deteriorated so badly that even the
inside was hazed and discolored. Not a lot you can do in that case
but anything is likely to help. I've heard of people wet-sanding
lenses and then shooting them with clearcoat. Sounds logical...
I've done this to 'Vair (and a Fiat) tail light lenses to brighten
them up (after a severe cleaning) and it does help.
