Another popular style of anime hair is hair that restricts one's vision.
Many anime (or related media - video games, etc.) feature characters with long forelocks hanging in front of one or both of their eyes. The bangs can range in thickness between merely obstructing sight (e.g. Trowa Barton from Gundam Wing) to extreme cases - hair that blocks any view of the eyes except from the most dramatic camera angles possible (Shermie from the King of Fighters games, Xelloss from Slayers, or for a non-anime example, Brian from Knights of the Dinner Table).
This style of anime hair tends to be used on characters to imply a sense of mystery and the exotic. However, it can also be used on comic relief characters, to separate them in the audience's mind from the serious main plot.
