Off-bike hydration

That's funny, polarized glasses give me headache and nausea. I hate the iridescence of everyone else's windshields!

Iridescence?? Hmmm....I don't see that on my good sunglasses. Maybe something else is going on here- perhaps it was just that my headache-causing sunglasses were cheapo in some other way that caused me headaches.
Anyhoo- my decent glasses are great for me.

I imagine that crummy sunglasses could indeed cause dehydration.....if they make you feel nauseous and you hurl periodically!

I've had glasses that didn't fit properly or put too much pressure (pinching or weight) on my nose give me big headaches. Those typically felt kind of like a sinus headache or weird migraine because of the pressure around the sinuses and behind the eyes. I am super picky about sunglasses.
