Based on high order aberration analysis of influence index of vision fatigue by watching 3D TV

Abstract

The purpose of this study was to assess the visual fatigue after watching 3D TV in wave-front aberration (WFA) test methods. The evaluation method is different from the previous visual fatigue test method (such as accommodation response, subjective assessment and electroencephalography). The self-developed wave-front aberrometer used to collect the data. 60 participants were recruited, who watched 3D TV by wearing two glasses respectively. SPSS18.0 was used for analysis and significance is defined as p < 0.05. The results show that MTF (Modulation Transfer Function) and means of WFA (3rd to 5th) of before and after watching 3D TV had significant differences (p < 0.05) and consistent trends. The RMS (root mean square) of WFA had no significance. Meanwhile, we found that the result of MTF of wearing different glasses had significant differences (p < 0.01). In conclusion, MTF and mean of WFA (3rd to 5th) can be used as the evaluation index of visual fatigue. In follow-up studies, more relationship between changes of higher-order aberrations (6th-35th order) and visual fatigue will be studied.
