>>2009231Hardware store safety glasses are good and cheap for starters. Get one pair that's clear and another one that's dark. Also make sure they have proper nose pads and rubber in the temples for good grip.
Also some mid-priced sunglasses are good that are plastic and not metal and glass. Avoid the dirt cheap gas station sunglasses because they will usually crack in half when you bend them.
If you can afford it, cycling specific sunglasses are great because they are usually made to be more comfortable for long rides. They usually also have lenses with a slight pink or amber tint from the inside to boost contrast.
