Pediatric vision development: a review of influencing factors and emerging insights

Vision development in pediatric populations is a multifaceted process influenced by biological, environmental, and experiential factors, forming the foundation for cognitive, social, and motor skills essential for lifelong learning and well-being. This narrative review explores the stages of pediatric vision development, emphasizing critical milestones such as visual acuity, depth perception, and color vision. Prenatal and neonatal factors, including maternal health, genetic predispositions, and early sensory exposure, play pivotal roles in shaping initial visual capabilities. During infancy and early childhood, visual abilities evolve through experiences that refine perceptual processing, enabling children to interact effectively with their environment. Environmental influences, such as nutrition, sunlight exposure, and socioeconomic status, further modulate vision development, while emerging challenges like excessive screen time are linked to rising myopia prevalence and digital eye strain. Common pediatric vision disorders, including amblyopia, refractive errors, and strabismus, are examined, highlighting the importance of early detection and intervention to prevent developmental delays and academic difficulties. Untreated vision impairments can lead to broader consequences, including mental health challenges, underscoring the need for systematic vision screening and parental education. Collaborative efforts involving healthcare providers, educators, and policymakers are essential to optimize visual outcomes. This review identifies gaps in current research and proposes future directions, including multidisciplinary studies, standardized screening tools, and guidelines for digital media use, aiming to enhance pediatric vision health and promote lifelong success for children.
