If the sun is not out I use a pair of MAGID safety glasses. These keep the wind off the eyes which is important if you are wearing contacts. These work great for the morning commute. When the sun comes out I have a pair of Native sunglasses I wear. The Natives are polarized and have a good lens tint which cuts the glare and makes the road/trail brighten up. My prescription glasses just don't cut it on the bike, to much wind around the sides.
