Went for a ride today - with my new sunglasses. Problem was that when inside my helmet with the face shield down, I get a holographic effect of colors that is pretty disconcerting - particularly when going in and out of sun and shade. I think its the polarization. May have to take them back and have them remade w/out the polarization - I like having my prescription in them (getting older sucks!) and they go into my helmet very nicely. They are Maui Jims the rimless style and titanuim metal - so are bendy and very light - they don't move around in my helmet.
None of the el cheapo sunglasses I have do this rainbow holographic effect.
Any other thoughts or observations?
Thanks guys!!!!
(and YESSSSS I got to ride today for the first time since November!!!! - 60F and sunny! WOO HOO)

You nailed it. Polarization makes for weird effects when looking through plastic.
I don't know why, but I'll bet someone does.  .
Alright!! The weather breaks in Flag. Maybe winter's done.
High 70s here for the last week. Very nice.

Yeah, Wade.
I see why you posted that link. 
From the site:
"In 1866 H. von Helmoltz related the effect to dichroism of a pigment of the retina and this early explanation has proven well founded, although the exact mechanism is complicated and a full explanation is still lacking."
