I just use tinted safety glasses for cycling. They wrap around somewhat and fit nicely. Mine also have readers on them so a tad more expensive:

Pyramex V2 Reader Bifocal For normal daytime going from sun to shadows.

Radians Rad-Sequel RSx Bifocal with Coffee Lens For really sunny conditions. But a little dark if you are going from sun to shadows often. Unless your eyes are younger and react quicker to the change.

If you don't need the bifocal they are even cheaper.

You can buy them by the gross and throw them away each ride. <grin> However using a cotton cloth to clean them, they'll last for a year or more. Use a paper towel and they be scratched up in less than two weeks.

Clear works well for twilight and night rides to keep the wind from drying your eyes.
