I was taught to practice what was termed the "warrior gaze" by a martial uncle. This is described as how to look when in hand to hand combat. Essentially, I was advised not to focus on any specific part of my opponent, but to not focus on anything specifically, and take in all visual data, including peripheral. This has served me well in sparring and in life. It also conforms to the hunter's gaze which I learned in Tom Brown's Field Guide to Wilderness Survival when I was a lad, where the unfocused gaze allows the hunter to see slight movements of prey, where prey cannot be discerned except by moving.
