Wang and Leung studied the indoor visual environments (IVE) in residential care homes (RDCHs). They learned that “The IVE, including opening design, interior design, and lighting conditions components, should be designed to satisfy older people's special visual needs. Hence, this study aims to investigate the effects of older people's subjective perceptions of the IVE on their visual-related physical health. In total, 197 questionnaires were collected from older persons living in RCHs. . . . the view out, window, corridors, furniture locations, curtains or louvers, handrails, and light level significantly affected the visual-related physical health of older people. Practical recommendations were proposed, including beds and seats near the windows with beautiful scenery, corridors with night lights and unblocked vision, automatic curtains with light sensors, handrails with a high color contrast with the background walls, minimum 200lx ambient lighting, etc.”
