Computer Vision Syndrome (CVS), also referred to as Digital Eye Strain (DES), is a common condition among college students and other digital-device users and is associated with prolonged near work, reduced blinking, and sustained visual attention. Conventional preventive strategies, including ergonomic optimization and scheduled visual breaks, primarily address environmental risk factors but do not directly target the perceptual-motor mechanisms underlying visual fatigue and oculomotor inefficiency. Perceptual-Motor Vision Training (PMVT) is an emerging complementary, non-pharmacological approach designed to enhance accommodation, vergence, oculomotor control, visuomotor integration, and visual information processing through structured visuomotor exercises. This narrative review synthesizes evidence from vision science, motor learning, and applied performance research to evaluate the potential role of PMVT in preventing or mitigating CVS-related visual fatigue in college students. Available evidence suggests that PMVT may improve selected visual and visuomotor functions. However, because most supporting studies involve athletic, pediatric, clinical, or non-CVS populations, its effectiveness for preventing CVS in healthy college students remains unproven. PMVT should therefore be considered an investigational complementary approach alongside ergonomic and behavioral strategies. Despite promising theoretical and preliminary empirical support, current evidence is limited by heterogeneous outcome measures, a scarcity of randomized controlled trials in non-athletic populations, and insufficient specification of training dosage and protocols. Future interdisciplinary research is required to establish standardized perceptual-motor metrics, determine dose-response relationships, and evaluate the clinical effectiveness and feasibility of PMVT as a low-cost complementary intervention for reducing digital task-related visual fatigue and improving visual performance in student populations.

Perioperative anxiety is a major challenge in the perioperative management of mental health. Statistics show that approximately 38.1% of surgical patients experience moderate-to-severe anxiety, which significantly impacts their quality of life and social function. In recent years, auricular neuromodulation (ANM) has emerged as a prominent research focus in the treatment of mood disorders, owing to its advantages, including safety, precision, and high efficacy. While preliminary studies have suggested the therapeutic potential of ANM in various chronic neurological and psychiatric conditions, robust clinical evidence specifically addressing the unique temporal window of the perioperative period is limited. Furthermore, the neurobiological mechanisms through which ANM alleviates perioperative anxiety are yet to be fully elucidated. This article is the first to comprehensively summarize the auricular targets, mechanisms, clinical efficacy and safety, existing technical limitations, and future development trends of auricular nerve electrical stimulation, binaural beat technology, and auricular therapy. We aim to provide a theoretical basis for the individualized treatment of perioperative anxiety with ANM and the development of innovative ANM technologies.
