Usually the left hand headlight is aimed so that it illuminates some of the side of the road (to see pedestrians) as well as the road ahead. Could be normal.
You can check your headlight adjustment against a wall if you're keen - you just have to mark the wall with the horizontal and vertical centres of the lights, then roll the car back a few metres and turn them on. The bright area should be down and to the left on low beam, straight ahead on high.
