“…Visual discomfort is defined as the subjective annoyance when watching visual stimuli, and is associated with various ocular, mental, and psychological symptoms, including eye pain, blurred vision, and nausea. Visual discomfort influences both the visual performance and safety [3], [4]. Subjects with visual discomfort take longer reaction time in detection tasks and report headache feelings.…”

“…Visual discomfort is related to the physical and psychological changes in various aspects, and the unpleasant feeling is effected by many factors, including environmental light, working hours, viewing position, personal factors (age, health, nicotine use, and more), and display device related factors, such as luminance, contrast, resolution, and color [1]- [4]. When viewers use a display device, the screen occupies most of the view, especially the center area.…”

Influence of Display Luminance on Visual Discomfort in Dark Ambient Based on Haemodynamic Response

et al. 2020

Display luminance is one of the most important factors that influence not only display performance but also visual discomfort greatly. To investigate the influence of display luminance and image content on visual discomfort, the haemodynamic response and subjective perception were recorded respectively when participants watched different visual stimuli. Different white levels (WLs) of display and images with different spatial amplitude spectra were adopted as the visual stimuli, and specific dark environment was applied in the study. The results showed that under dark ambient condition, the WL had significant influences on visual discomfort, which varied in images with different spatial amplitude spectra. The findings also indicated that, for visual discomfort measurement, the sensitivity of haemodynamic response was better than subjective evaluation.

“…As an organ that directly feels light stimulation, the change of eye activity can most directly reflect visual fatigue. Previous studies have confirmed that the decline of critical fusion frequency(CFF) reflects the weakening of human eye function, which can be used to measure the degree of human visual fatigue [7]. The lower the CFF value, the greater the fatigue degree [8].…”

The Impact of Color Rendering on Visual Fatigue in Interior Zone of Tunnel

Judicious use of lamps is of profound significance to improve the internal traffic safety of tunnels. This study evaluated the effect of LED color on human visual fatigue under mesopic vision category. According to the difference of human eyes’ response to different wavelengths of light radiation, the mesopic vision spectral luminous efficiency curve is applied to the visual fatigue evaluation methods. Taking the critical fusion frequency as the physiological index, the detection experiment of human visual fatigue was carried out in the simulated tunnel environment. The results show that spectrum with high color rendering index has a positive effect on alleviating drivers’ visual fatigue, and is more suitable for tunnel interior lighting.

“…Curved monitors with a carefully selected display curvature radius can benefit monitor users by reducing distracting reflections (Zannoli & Banks, 2017), preventing visual fatigue (Lee & Kim, 2016;Park et al, 2017), and improving visual task performance (Park et al, 2017(Park et al, , 2019. Such beneficial effects of curved monitors compared to flat monitors of equal size (especially for the visual perception of a viewer centered at a monitor) can be attributed to the fact that the curved display surface is closer to an empirical horopter line, concave loci of perceived equidistance (Foley, 1966).…”

“…When visual stimuli are positioned near an empirical horopter, the ocular accommodation speed increases (Barfield & Furness, 1995), and the demands for accommodation and vergence to avoid double vision (i.e., diplopia) and correct the blurred image on the retina decrease. In particular, if the magnitude of display curvature radius approaches a given viewing distance, legibility is improved (Park et al, 2017(Park et al, , 2019 and visual fatigue is less pronounced (Park et al, 2017). With such a configuration, relative to flat screens, curved screens of equal size provide a wider horizontal field of view (FOV) and reduce variability in viewing angles and horizontal viewing distances across the screen, where a horizontal FOV is the angle subtended on the retina by the horizontal dimension of the screen and a viewing angle refers to the angle between a horizontal line of sight and a normal line to a fixation point on the display surface.…”

Objective The aim of this study is to examine the interactive effects of display curvature radius and display size on visual search accuracy, visual search speed, and visual fatigue. Background Although the advantages of curved displays have been reported, little is known about the interactive effects of display curvature radius and size. Method Twenty-seven individuals performed visual search tasks at a viewing distance of 50 cm using eight configurations involving four display curvature radii (400R, 600R, 1200R, and flat) and two display sizes (33″ and 50″). To simulate curved screens, five flat display panels were horizontally arranged with their centers concentrically repositioned following each display curvature radius. Results For accuracy, speed, and fatigue, 33″–600R and 50″–600R provided the best or comparable-to-best results, whereas 50″–flat provided the worst results. For accuracy and fatigue, 33″–flat was the second worst. The changes in the horizontal field of view and viewing angle due to display curvature as well as the association between effective display curvature radii and empirical horopter (loci of perceived equidistance) can explain these results. Conclusion The interactive effects of display curvature radius and size were evident for visual search performance and fatigue. Beneficial effects of curved displays were maintained across 33″ and 50″, whereas increasing flat display size from 33″ to 50″ was detrimental. Application For visual search tasks at a viewing distance of 50 cm, 33″–600R and 50″ 600R displays are recommended, as opposed to 33″ and 50″ flat displays. Wide flat displays must be carefully considered for visual display terminal tasks.
