With the development of 3D display

3D brings people a real sort of visual experience

and it also lead to its safety problem. Visual fatigue brought by 3D display is the first safety issue. By contrast objective assignments before and after experiment

and combined with the subjective statement

the visual fatigueis varied with difference of display mode and screen disparity. The experimental results show that 2D display and 3D display have a significant difference and the polarization 3D display is not easy to cause visual fatigue. With the increase of screen disparity

visual fatigue appears as stype of growth. Started relatively flat

and then rapidly rising.
