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!
