This invention proposes a 3D display and visual training device based on a mobile phone, comprising several lenses, a first light valve, a partition, an elastic fixing member, and a mounting slot. The first light valve and the focal plane of the lens form a first angle. The mounting slot is used to mount the mobile phone, and the elastic fixing member is used to ensure that the mobile phone's display screen is tightly fitted to the first light valve. The display screen and the focal plane form a second angle, which is equal to the first angle. The mobile phone display screen displays two corresponding entertainment images. The partition is used to separate the left and right images. Each image has pixels. This invention proposes that the display screen is tilted, and pixels at different heights in the image trigger different eye accommodations. The movement of pixels in different height areas can achieve visual training, combining entertainment and visual training. This invention also proposes to set the distance between pixels at different image heights so that the eye convergence triggered by the pixel distance is equal to the eye accommodation, effectively solving the problems of fatigue and dizziness.
