You could spend a few bucks less on a dingy pair of sunnies at the gas station, or you could hold out for the Oakley Women's Hold Out Sunglasses. Sure, it seems like an unwise investment since both shades keep some sunlight at bay, but the Hold Out's polarized lenses reduce glare so you can see more when you're cruising the town on your single-speed. Oakley built these sunglasses out of stress-resistant, impact-resistant materials to keep them shiny for seasons, whereas the gas station pair falls apart in a month.
