“…From both the safety and scientific integrity perspectives, blind spots to the central visual field would be more problematic and thus warrant more attention for investigation. Additionally, findings from these studies have been inconsistent -reporting impairments (Rahnev et al, 2013;Cai et al, 2014;Chiou and Lambon Ralph, 2016;Chen et al, 2020), improvements (Waterston and Pack, 2010;Clavagnier et al, 2013), and non-significant changes (Waterston and Pack, 2010;Brückner and Kammer, 2014;Kaderali et al, 2015;Abuleil et al, 2021) to vision. This is likely due to variability in methods, including differences in stimulation intensity, performance measurement, target localization, and task demands.…”
