The word 目光 is formed through a conceptual metaphor where 目 (eye) is combined with 光 (light) to create a new, integrated meaning. It visually and abstractly blends the physical organ of sight with the quality of illumination, suggesting the "light of the eye" or one's line of sight. This synthesis produces the sense of a directed gaze, one's vision, or by further extension, the perceptiveness and perspective that emanates from a person.
