| 摘要 | The study was conducted to evaluate the changes of visual perception processing ability after using circularly polarized light LCD and linearly polarized light LCD for a continuous month by eye-movement tracking method. 47 subjects were randomly divided into circularly polarized light group (experimental group) and linearly polarized light group (controlled group). A 2 (times of measurement: before and after) * 2 (display equipment: circularly polarized light LCD and linearly polarized light LCD) experiment was designed. There was 1 month interval between the two times of measurement. The dependent variables were corrective eye frequency and tracking gain. The results showed that there was critically significant difference of eye-movement tracking gain between the circularly polarized light condition and the linearly polarized light condition. The post hoc comparison showed that the tracking gain after 1 month was significantly more than that of before 1 month. Therefore, the influence of circularly polarized light LCD on visual perception processing ability was slighter than that of linearly polarized light LCD for a long term. |
