N2 - Purpose: Change of the fatigue and the visual function before and after viewing 2D and 3D movie in 3D TV was analyzed using Simulator Sickness Questionnaire(SSQ) and the visual function test. Methods: 15 participants with the normal visual function, the normal stereopsis, the corrected visual acuity of higher than 0.8 and the age of range from 23 to 29 years (average age of 25.3±1.6 years) were selected. Participants watched 2D or 3D movies for 30 minutes on 3D TV of the diagonal size of 47 inch at the distance of 2.5m. Before and after watching movies, Fatigues (survey of 5 categories, 28 items) and the visual function such as phoria at the far and the near, near point of convergence and relative accommodation were measured and analyzed. Results: In the fatigue survey between before and after movies, scores of Burry (p=0.019), Dry eye (p=0.023) and Eye strain (p=0.003) increased statistically significantly in viewing 2D movie while scores of Eye strain (p=0.019) and Dizzy (p=0.047) increased statistically significantly in viewing 3D movie. Among 28 items, changes occurred only 3 items in 2D and 2 items in 3D and the amount of score change was not so large. And no statistically significant difference was measured in visual function test. Conclusions: Fatigues in viewing 2D and 3D movies was measured to be the same. This result contrasted with the previous report of increase of fatigue in viewing 3D. This may be attributed to the different 3D viewing environment such as 3D contents, viewing distance and 3D display. It also implies that the fatigue in viewing 3D TV under the specific condition would not be the serious compared with fatigue in viewing 2D.
