Optometry & Visual Performance 170 Volume 14 | Issue 2 | June 2026 Article • The Extensive Relationship Between Eyes and Mind: Understanding the Psychology Behind Your Vision Pratyush Dhakal, MPH, Optometrist • Chattanooga Eye Institute • Chattanooga, Tennessee Amrita Samanta Dhakal • Chattanooga, Tennessee ABSTRACT The perception of sight, commonly regarded as a direct and objective interpretation of reality, is, in fact, a deeply subjective process actively modulated by an individual’s psychological state. This article explores the burgeoning field of psychosomatic ophthalmology, which investigates the profound impact of human psychology on visual health and perception. It synthesizes evidence from ophthalmology, neuroscience, and psychology to argue for a holistic, mind-body approach to eye care. The article details the neurobiological pathways through which psychological distress, particularly chronic stress and anxiety, adversely affects ocular health. It elaborates on the role of the hypothalamic-pituitary-adrenal (HPA) axis and the sustained release of cortisol, which can impair blood flow, increase inflammation, and disrupt the blood-retinal barrier. These mechanisms are discussed as contributing factors in the progression of sight-threatening diseases such as glaucoma, age-related macular degeneration (AMD), diabetic retinopathy, and dry eye disease. Furthermore, the review examines how transient emotional states and cognitive processes like attention actively shape visual perception. Evidence is presented demonstrating that mood can alter the perceived saturation of color, while attentional biases, influenced by fears and desires, Introduction The act of seeing, for most of us, feels effortless and immediate. We open our eyes, and the world simply appears, a faithful, high-definition stream of reality delivered directly to our consciousness. But this perception of an unvarnished truth is a masterfully constructed illusion. A growing and compelling body of scientific evidence reveals that our vision is not a passive reception of light, but an active, dynamic process deeply intertwined with our psychological landscape. The intricate workings of our minds—our stress levels, emotional states, attentional focus, and even our core personality traits—profoundly shape, tint, and, at times, fundamentally transform what we see. This emerging understanding, situated at the crossroads of both optometry and ophthalmology and its inter-disciplinary relations to neuroscience and the subject of psychology itself, is ushering in a new era of “psychosomatic ophthalmology,” demanding a more holistic and integrated approach to preserving the precious gift of sight.1 The term psychosomatic ophthalmology was first mentioned in the literature in 1947 by Harrington.2 Interestingly, there are approximately 20 articles published on this topic up to 2012, and from 2012 to 2025, approximately 325 articles were found on online databases like Pubmed and the Cohrane Library. The Stressed-Out Synapse: Neurobiological Pathways from Mind to Eye The connection between psychological distress and vision is not merely circumstantial; it is engraved into our very neurobiology. When we experience chronic stress or anxiety, our body’s ancient Pratyush Dhakal, MPH, Optometrist Chattanooga, Tennessee Lead Clinical Research Coordinator, Chattanooga Eye Institute Optometry degree, Lumbini Eye Institute,Nepal.

The influence of stable personality traits, such as neuroticism and optimism, on perceptual biases and long-term visual health outcomes is also considered.
