"Blended Vision" is a duo-screen video. The screen on the left shows a video about Lau's experience of accompanying his father during eye surgery. As the father's vision gradually becomes disabled, he begins to rely on his daughter's eyes to see the world, and the roles of caregiver and caretaker are reversed. In the series of events from the discovery of the disease to examination, surgery, and recovery, the emotional changes between father and daughter constantly overlap and stagger, and are connected by an invisible line. The video on the right, Lau uses a camera lens to imitate the blurred vision from the eyes of her father, and returns to the places he passes by every day, the park near their home, the same teahouse, the same bus route, the same way home... to reproduce those things that are seen repeatedly in the scenery.
