Here the word "eyes" represents the person who is looking. The writer speaks of a person being committed to doing the right thing as if that person were constantly looking forward without turning his head to look in another direction. Alternate translation: "Always look straight ahead and fix your gaze straight before you" (See: [[rc://en/ta/man/jit/figs-synecdoche]] and [[rc://en/ta/man/jit/figs-metaphor]])
