In the vertigo of life(1969)

A promising civil engineer, Stelios, delays his marriage to his beloved Anna because he wants to marry off his sisters first. When Anna becomes engaged to a wealthy sailor and his plans for a major project are rejected, Stelios leaves for Kuwait to work. In an accident, he loses his sight and returns to Greece. Anna will wait for him—since she never married and remains faithful to him—and with the help of a doctor, Stelios will have his eyes healed. His luck has changed radically and the same man who initially rejected his plans will now hire him in his business.
