If you begin to learn the kick you should look over the shoulder on your target, it is more a control if your leg realy does what it should. However you should not even think about using it untill you can throw it blind. The foot should be faster than your own eye, by the point you actualy manage to turn your head the foot went over 3/4 of it's way already, there's no way you actiualy could have time on fucusing on the target without thwarting your kick.
