Polarized safety glasses from your local hardware store are awesome
Your local REI will have an in-house brand with neat all-rounder outdoor sunglasses.
I'm personally a big fan of the Speedcraft sunglasses, but I buy knock-offs from Amazon. They work great for me! Multiple lenses, replaceable / interchangeable everything... $30 shipped with 3 lenses, a case and a microfiber pouch.
