Abstract
The human eye, a pivotal sense organ, plays a crustal role in shaping our perception of the world. Researchers have consistently delved into its functional aspects, reflecting its paramount significance. Comprising intricate components, the human eye collectively orchestrates the intricate symphony of human visual perception. This study primarily focuses on the human pupil—a pivotal component of this sensory apparatus. In this paper, we rigorously investigate the dynamics of the human pupil through a comprehensive linear control analysis. Our approach involves deriving a linearized model based on prior research findings. Subsequently, we apply advanced control analysis techniques to gain deeper insights into its behavior. The obtained results provide valuable contributions to our understanding of the intricate dynamics governing the human pupil. This research sheds light on the complex interplay of factors that govern the behavior of the human pupil, offering insights with potential applications in fields such as ophthalmology, optometry, and human-computer interaction.
