Why I like polarized sunglasses

1. Good level of light reduction so the giant burny thing in the sky doesn't hurt me.
2. Personal rainbows from many protective films placed on business and train windows. (And our apartment!)
3. Entertaining hyper-3d effects from certain reflective surfaces, such as my shoes, at certain angles of sunlight.
4. Zombies appear blue through them, making them very easy to identify and avoid.

Off to the train station now. Not much cover -- wish me luck!
