The kanji 直 is a pictograph. It depicts a vertical eye 目 (me) with a vertical line through it. The vertical line represents the concept of straightness, thus, the whole character implies "straight" or "direct" vision. The "eye" component suggests seeing things clearly and directly, without obstruction or deception.
