I tried the yellow lenses a few times years ago. Didn't think they had much effect, but maybe that is just me?
Along the upper edge of the driver's side window on the 90 I have placed a sunstrip to cope with low sun from that side and did the same with several of my commutacar/shopping trolleys over the last few years.
