“…This short-term effect indicates that the 5-min massage is an effective and easy method for improving vision. Eye fatigue associated with visual display terminals (including head-mounted displays) is currently a major issue that is being studied from various viewpoints, (27,28) and the present findings indicate that a simple intervention allows the transient recovery of eye fatigue.…”

Introduction: The ocular blood flow (OBF) is responsible for supplying nutrition to the retina, which plays a fundamental role in visual function. Massage is expected to improve the blood flow and, consequently, vascular function. The aim of this study was to determine the shortterm and long-term effects of periocular massage on OBF and visual acuity. Methods: The OBF and visual acuity were measured in 40 healthy adults aged 20–30 years before and after massage, and also in control subjects. Three massage methods were used: applying periocular acupressure (“Chinese eye exercise”: CE), using a facial massage roller (MR), and using an automated eye massager (AM). The OBF and visual acuity were first measured before and after applying each type of massage for 5 min. Eye massage was then applied for 5 min once daily over a 60-day period, while the control group received no massage. The same measurements were then performed again. Results: Performing short-term periocular massage showed significant interactions in time and massage effects on visual acuity in CE and AM groups, and on OBF in AM group, while 60-day massage period exerted no significant effects. No significant relationship was found between OBF and visual acuity changes. Conclusions: These results suggest that short-term periocular massage with Chinese eye exercise and automated eye massager can improve OBF and visual acuity, although no causal relationship was supported.

“…Visual fatigue appears to be time-related: the more prolonged the VR exposure, the higher the visual fatigue. Guo et al (2019b) find that symptoms are increasingly severe and that the severity increases faster during the first 20 min. Guo et al (2020) tested exposures of almost eight hours to VR and reported increasingly impacted accommodative response and pupil size.…”

“…This sensorimotor conflict mainly explains visual fatigue with HMDs (Fuchs 2017). A new generation of HMDs still causes visual fatigue (Souchet et al 2018(Souchet et al , 2019(Souchet et al , 2021aHirota et al 2019;Wang et al 2019;Yoon et al 2020) and visual discomfort (Cho et al 2017;Guo et al 2017Guo et al , 2019bSouchet et al 2018;Bracq et al 2019). A lack of contributions to document that effect (beyond merely knowing that it still exists for HMDs) has been pointed out (Szpak et al 2019).…”

A narrative review of immersive virtual reality’s ergonomics and risks at the workplace: cybersickness, visual fatigue, muscular fatigue, acute stress, and mental overload

et al. 2022

This narrative review synthesizes and introduces 386 previous works about virtual reality-induced symptoms and effects by focusing on cybersickness, visual fatigue, muscle fatigue, acute stress, and mental overload. Usually, these VRISE are treated independently in the literature, although virtual reality is increasingly considered an option to replace PCs at the workplace, which encourages us to consider them all at once. We emphasize the context of office-like tasks in VR, gathering 57 articles meeting our inclusion/exclusion criteria. Cybersickness symptoms, influenced by fifty factors, could prevent workers from using VR. It is studied but requires more research to reach a theoretical consensus. VR can lead to more visual fatigue than other screen uses, influenced by fifteen factors, mainly due to vergence-accommodation conflicts. This side effect requires more testing and clarification on how it differs from cybersickness. VR can provoke muscle fatigue and musculoskeletal discomfort, influenced by fifteen factors, depending on tasks and interactions. VR could lead to acute stress due to technostress, task difficulty, time pressure, and public speaking. VR also potentially leads to mental overload, mainly due to task load, time pressure, and intrinsically due interaction and interface of the virtual environment. We propose a research agenda to tackle VR ergonomics and risks issues at the workplace.

“…A study of VR devices found that despite advances in technology, head-mounted displays and helmet-mounted display systems create visual discomfort after extended usage [26]. To determine if periods of rest could help visual fatigue during head-mounted display VR experiences, Guo et al found that short rest during continuous use of the head-mounted display induced more severe symptoms of subjective visual discomfort, but reduced objective visual fatigue [27]. Future research should continue to examine this issue of fatigue and ways that technology can reduce it.…”

Extended Reality Technologies in Nutrition Education and Behavior: Comprehensive Scoping Review and Future Directions

et al. 2020

View full text Add to dashboard Cite

The use of Extended Reality (XR) (i.e. Virtual and Augmented Reality) for nutrition education and behavior change has not been comprehensively reviewed. This paper presents findings from a scoping review of current published research. Articles (n = 92) were extracted from PubMed and Scopus using a structured search strategy and selection approach. Pertinent study information was extracted using a standardized data collection form. Each article was independently reviewed and coded by two members of the research team, who then met to resolve any coding discrepancies. There is an increasing trend in publication in this area, mostly regarding Virtual Reality. Most studies used developmental testing in a lab setting, employed descriptive or observational methods, and focused on momentary behavior change like food selection rather than education. The growth and diversity of XR studies suggest the potential of this approach. There is a need and opportunity for more XR technology focused on children and other foundational theoretical determinants of behavior change to be addressed within nutrition education. Our findings suggest that XR technology is a burgeoning approach in the field of nutrition, but important gaps remain, including inadequate methodological rigor, community application, and assessment of the impact on dietary behaviors.
