Abstract
In this study we compare visual function in individuals with low vision using three different models of augmented reality (AR) devices. Three models of AR devices were used: Ziru, IrisVision, and NuEyes-Pro3. 27 individuals with low vision (< 20/60) were recruited. The distance visual acuity (VA) was measured in High luminance high contrast (HLHC), High luminance low contrast (HLLC), Low luminance high contrast (LLHC), and Low luminance low contrast (LLLC) settings. The other tests were near VA, distance CS, and near CS. The change in visual function without and with AR devices was analyzed. Out of 27 participants, 17 were female. The mean age was 66.7 ± 18.2 years. The mean baseline VA was 0.79 logMAR in HLHC, 0.92 in HLLC, 0.92 in LLHC and 1.11 in LLLC. The baseline near VA was 2.09M, distance CS was 1.08 logCS, and near CS was 1.12 logCS. Distance and near vision showed significant differences with both Ziru and IrisVision (p < 0.01), but not with NuEyes. There was a significant change in CS using Ziru and IrisVision for both distance and near (p < 0.05) but both reduced significantly with NuEyes (p < 0.01). Majority of the visual functions had improvement with Ziru and IrisVision, whereas the improvement was limited with NuEyes.
