“…Yan Xiaolin discovered linearly polarized light was easier than circularly polarized light to cause visual fatigue through the eye blink frequency recorded by the electro-oculogram (EOG) during the study of influence of circularly polarized light liquid crystal TV on eye fatigue [2]. Zhang Yunhong, Zhang Li et al also got the same result in their study [3,4].…”

Evaluate the effects of long term continuous use of circularly and linearly polarized liquid crystal display (LCD) on the inhibition of human response by eye tracking technique. 47 subjects were randomly divided into two groups, one group was circularly polarized (experimental group) and the other group was linearly polarized (control group). The experiment used 2 (test times) *2 (display devices) design. The interval between the two tests was 1 month. The dependent variables were the saccade accuracy, saccade amplitude and saccade latency in completing the saccade task. The research results showed that the antisaccadic accuracy of circularly polarized group was significantly higher than that of the linearly polarized group (F (1,72) =4.94, p<0.05); The antisaccade distance of the circularly polarized group was significantly greater than that of linearly polarized group (F(1,72) =3.98, p<0.05). Antisaccade accuracy and antisaccade amplitude indexes can well reflect the effects of experimental conditions. The extent of reponse inhibition decrease of circularly polarized group (experimental group) was lower than that of linearly polarized group (control group). Therefore, the results showed that the effect of reponse inhibition of the long‐term use of circularly polarized light displays was ligther than that of the long‐term use of linearly polarized displays.

“…Both prolonged repeated use of ocular muscles (Hsu & Wang, 2013) and accommodative response to similar focal distances (Young, 2004) can cause visual fatigue, resulting in headache and degraded reading task performance (Sheedy, 1992a(Sheedy, , 1992b. To measure visual fatigue, diverse measures are available including questionnaires (Benedetto et al, 2013;Li et al, 2012;Steenstra et al, 2009), CFF (Chi & Lin, 1998;Nahar et al, 2011), blinking duration and frequency (Zhang et al, 2015), EMG and EOG (Kaneko & Sakamoto, 2001), and pupil accommodation speed (Lee et al, 2009). Visual fatigue can lead to degraded visual task performance as well as oculomotor changes (Tsai et al, 2007;Van Orden et al, 2001).…”

With more curved display products in the market and more exposure to such products, it is necessary to examine the effects of display curvature and task duration from the ergonomics perspective. The current study examined the effects of these two factors on visual performance, visual fatigue, visual discomfort, and display satisfaction during proofreading tasks. We incorporated five display curvatures (600R, 1140R, 2000R, 4000R, and flat) and five task durations (0, 15, 30, 45, and 60 min). Each of 50 individuals completed a 1-hr proofreading task at one of five display curvature conditions. The horizontal viewing distance was fixed at 600mm. Proofreading performance (speed and error rate), subjective visual fatigue [on ECQ (Eye Complaint Questionnaire)], physiological visual fatigue [CFF (Critical Fusion Frequency), blink duration, and blink frequency], visual discomfort (on VAS), and display satisfaction (on VAS) were measured. The highest mean proofreading speed was at 600R. The mean proofreading speed and error rate increased by 15.5% and 22.3%, respectively, over the 1-h task. The mean ECQ score and visual discomfort increased by 188.6% and 107.2% during 45 and 60 min of the task, respectively. The mean CFF and display satisfaction decreased by 0.49Hz and 11.2% during 15 and 15-45 min of the task. A polynomial regression model for subjective visual fatigue was developed (adjusted R2 = 0.6). These findings can be used when determining ergonomic display curvatures and predicting visual fatigue.
