Sunglasses question indeed! There's no need to show off just because you live in the best climate in the world. Spare some thought for most of the rest of us facing a few months when it would be wonderful to have the problem!
I've always understood (can't remember from where) that polaroids should be avoided because of the problem if the cockpit windshield is also polarised. I've never experienced it, but have noticed most specialist 'aviator' sunglasses are not polarised.
Unlikely to be a problem in civvy helicopters I suspect.
Hope all is well in glorious Southern California.
