“…García-Muñoz [2] Shrestha [3] Franco [4] Darko-Takyi [5] Liu [6] Current showed the prevalence rate of the 18-35-year-old population to be 32.05% [4] and 36.1% [6] , respectively. Meanwhile, the prevalence rate of college students from Spain, Malaysia, Ghana, and Nepal was 13.15% [2] , 40% [12] , 34.3% [5] , and 27.82% [3] , respectively.…”

“…E lectronic products and close-eye tasks have become increasingly common, leading to a high prevalence of accommodation and non-strabismic binocular vision dysfunction among college students [1][2] . Symptoms of binocular eyestrain, such as red vision, headaches, diplopia, difficulty concentrating, and fatigue, were reported inconsistently in different kinds of literature [2][3][4][5][6] . These symptoms among college students were found to be related to abnormal adjustment function and/or non-strabismic binocular visual function [7] .…”

AIM: To investigate the frequency and associated factors of accommodation and non-strabismic binocular vision dysfunction among medical university students. METHODS: Totally 158 student volunteers underwent routine vision examination in the optometry clinic of Guangxi Medical University. Their data were used to identify the different types of accommodation and non-strabismic binocular vision dysfunction and to determine their frequency. Correlation analysis and logistic regression were used to examine the factors associated with these abnormalities. RESULTS: The results showed that 36.71% of the subjects had accommodation and non-strabismic binocular vision issues, with 8.86% being attributed to accommodation dysfunction and 27.85% to binocular abnormalities. Convergence insufficiency (CI) was the most common abnormality, accounting for 13.29%. Those with these abnormalities experienced higher levels of eyestrain (χ2=69.518, P<0.001). The linear correlations were observed between the difference of binocular spherical equivalent (SE) and the index of horizontal esotropia at a distance (r=0.231, P=0.004) and the asthenopia survey scale (ASS) score (r=0.346, P<0.001). Furthermore, the right eye's SE was inversely correlated with the convergence of positive and negative fusion images at close range (r= -0.321, P<0.001), the convergence of negative fusion images at close range (r=-0.294, P<0.001), the vergence facility (VF; r=-0.234, P=0.003), and the set of negative fusion images at far range (r=-0.237, P=0.003). Logistic regression analysis indicated that gender, age, and the difference in right and binocular SE did not influence the emergence of these abnormalities. CONCLUSION: Binocular vision abnormalities are more prevalent than accommodation dysfunction, with CI being the most frequent type. Greater binocular refractive disparity leads to more severe eyestrain symptoms.

“…Additionally, similar experiences and symptoms may occur due to accommodation anomalies, that also result in a failure to maintain a focused retinal image. Overall, more than 30% of the population have moderate to poor stereo vision (stereoanomaly: Hess et al, 2015) due to vergence and accommodation anomalies typically combined with a refractive error (Atiya et al, 2020;Dahal et al, 2021;Franco et al, 2021).…”

Full accessibility to eXtended Reality Head-Mounted Displays (XR HMDs) includes a requirement for well-functioning eyes and visual system. Eye and vision problems—that affect visual skills and abilities to various degrees—are common and may prevent an individual from comfortably wearing and using XR HMDs. Yet, vision problems have gained little attention in the XR community, making it difficult to assess the degree of accessibility and how to increase inclusivity. This perspective article aims to highlight the need for understanding, assessing, and correcting common eye and vision problems to increase inclusivity—to help broaden a responsible uptake of XR HMDs. There is a need to apply an interdisciplinary, human-centered approach in research. Guidelines are given for conducting reproducible research to contribute to the development of more inclusive XR technologies, through consideration of the individual variations in human visual skills and abilities.

“…Additionally, 10.9% had binocular vision abnormalities, and 21.1% had accommodative problems. Additionally, following convergence insufficiency (7.1%) and accommodative infacility (5.8%), accommodative insufficiency (11.5%) was the most common disease (Franco et al, 2022).…”

Background: One of the most important senses in the human body is vision, which is used in many daily activities. Sports vision training is a rapidly expanding industry in the field of visual-skill development. Sports vision training had previously only been used on athletes to enhance their visual abilities and athletic performance. Still, given the pandemic’s effects and the rise in ocular ailments among college students, there is an urgent need to address their visual issues. Purpose: To explore the need of sport vision training in higher education institutes. Methods: This article examines the value of sports vision training, its necessity, and how it can be incorporated to meet the increased visual needs of college students. 170 articles were identified in this study, of which 38 were included. The search techniques included “Citation Searching” and “Using Keyword.” Google Scholar, Semantic Scholar and PubMed were used as the search engines. Both AND and OR were used as Boolean operators. Conclusions: This review also sheds a broad light on the visual problems among university students and why there is a high need to tackle them. This research concluded that to overcome the visual problems among university students, sports vision training should be opted for in higher education institutes.
