Abstract:
Given the crucial role of medical buildings in emergency situations, health maintenance, and disease control, as well as the importance of ensuring user comfort, recent architectural studies have emphasized the need to revise design criteria. One of the key considerations for creating comfortable environments in hospitals is managing undesirable lighting. Although research underscores the importance of sufficient and appropriate natural light in reducing patients' length of stay, reliance on general standards may not adequately address the needs of specific patient groups. To assess visual comfort in an ophthalmic ward while minimizing the potential biases and limitations of human studies, this research utilized an in vivo animal model using rabbits. Rabbits were selected due to their physiological similarities to humans, especially regarding the visual system, making them appropriate subjects for studying cataract-related reactions. Moreover, animal studies offer better control over environmental factors, ethical considerations, and reproducibility compared to human studies, where individual variations and external factors can affect results. In this study, daylight simulation and its effects were analyzed through a point-by-point illuminance comparison using Rhinoceros modeling software, Grasshopper, and HoneybeePlus version 1.4.0. The results demonstrated a 15.19% discrepancy between the visual comfort limits set by international standards and the expectations of patients with cataract eye problems. This inconsistency has led to a 22.44% reduction in the comfort levels within the patients' rooms.
