“…High disparity can be fused without diplopia, but high disparity induces visual fatigue (Shibata et al, 2011;Patterson, 2015;Fuchs, 2017). Negative parallaxes lead to higher visual fatigue than positive (Sun et al, 2020) Shibata et al (2011 assume that the maximum and minimum relative distance of the comfort zone is between 0.8 and 0.3 D Apply ±1.0 • disparity to avoid visual fatigue (Bando et al, 2012;Matsuura, 2019;Hibbard et al, 2020) However, according to Patterson (Patterson, 2009), fusion is possible from 80 arc minutes for high spatial frequencies and up to 8 • for low spatial frequencies images VF_10 IV…”

Virtual reality (VR) can induce side effects known as virtual reality-induced symptoms and effects (VRISE). To address this concern, we identify a literature-based listing of these factors thought to influence VRISE with a focus on office work use. Using those, we recommend guidelines for VRISE amelioration intended for virtual environment creators and users. We identify five VRISE risks, focusing on short-term symptoms with their short-term effects. Three overall factor categories are considered: individual, hardware, and software. Over 90 factors may influence VRISE frequency and severity. We identify guidelines for each factor to help reduce VR side effects. To better reflect our confidence in those guidelines, we graded each with a level of evidence rating. Common factors occasionally influence different forms of VRISE. This can lead to confusion in the literature. General guidelines for using VR at work involve worker adaptation, such as limiting immersion times to between 20 and 30 min. These regimens involve taking regular breaks. Extra care is required for workers with special needs, neurodiversity, and gerontechnological concerns. In addition to following our guidelines, stakeholders should be aware that current head-mounted displays and virtual environments can continue to induce VRISE. While no single existing method fully alleviates VRISE, workers' health and safety must be monitored and safeguarded when VR is used at work.
