Description

Technical Field

[0001] The utility model belongs to the technical field of ophthalmological training displays, and in particular relates to a light field 3D ophthalmological training display. Background Art

[0002] The vision training device is a medical device that exercises the eye muscles by training the ability of the eyeball to rotate inward and outward, so that the visual axis of both eyes can move continuously to train the three muscles that dominate vision - ciliary muscle, extraocular muscle, and iris muscle. Through coordinated exercise, the paralysis and stiffness of the above muscles can be relieved, making them strong and flexible, thereby improving the adjustment ability of the eye muscles, and finally achieving a clear image of the object on the retina, which plays the purpose of restoring vision. The vision training device is a kind of ophthalmic training display device;

[0003] However, when using a vision training device to exercise the eye muscles, the vision training device generally has a 2D display, so that the displayed image can only be presented in one plane in the vision, which reduces the eye muscle exercise. Utility Model Content
