The only practical answer is to use non-polarising sunglasses; brown tint
is good for cloud definition. A reddish tint is even better, but at the
expense of false colour which can cause problems when identifying crop
types for the field selected, and in reading paper charts.

I found it practical to punch holes in my polarized clip-ons. That
eliminated the polarization over the area of the panel, and also the
tinting: no LCD problems, no paper chart problems (not that I look at a
chart very often). It does not solve the tinting problem for crops,
because I'm using bifocal glasses, and the holes are over the bifocal part.

I'd probably use non-polarized clip-ons if I could find them. If you
don't need distant vision correction, there are polarized "sunreaders"
available that have non-polarized, non (or lightly)-tinted inserts with
correction for reading.

These look like the inserts are tinted, unlike the ones I have. Since
the inserts aren't polarized, looking at LCDs isn't a problem.
