Polarising sunglasses are likely to cause colour patterns from stresses in the screen of most planes so should be avoided. Ifyou normally wear glasses then get prescription sunglasses and get them to tint them a bit lighter than normal. If not then proper rayban aviators are good, there was a good reason for graduated tints so they are clear at the bottom, so you can see instruments inside the cockpit not fashionable these days but functional.
