Embodiment 1
[0054] see Figure 1-11 , a vision training instrument, comprising a housing 1, the front of the housing 1 is provided with a viewing hole 4, the inside of the housing 1 is provided with a cavity 2, and the housing 1 is provided with a light-emitting device 6, the light-emitting device 6 is used to The light source is emitted, and the light-emitting device 6 is provided with an optical wedge device 5; the optical wedge device 5 includes a plurality of deflection lenses 51, the deflection lenses 51 deflect light rays, and the plurality of deflection lenses 51 are connected to each other through a connecting piece 52; The light emitting device 6 includes a circuit board 62, the circuit board 62 is connected with a second laser generator 61 for positioning and several first laser generators 63 for training, and several first laser generators 63 are arranged on the second At the periphery of the laser generator 61, through the beam deflection function of several arrayed deflection...
Embodiment 2
[0082] see Figure 4-8 , Figure 8 The dotted line in the middle of the eye is the irradiation area of the laser. The detection device 7 is arranged in the housing 1, and the detection device 7 is used to detect the light source reflected by the sclera. The detection device 7 includes a control circuit board 73, a photoelectric sensor 72, and a control circuit. The board 73 is connected to the inner wall of the casing 1, and the photoelectric sensor 72 is arranged on the circuit board 73. When the light source emitted by the array light source illuminates the eyes, the light projected on the cornea enters the fundus through the pupil, and is projected to the edge of the cornea and the inner side of the eye. The light on the sclera is reflected, and the overall detection device 7 can detect the intensity of the reflected light at the edge of the cornea in real time, and monitor the position of the user's eyeball in real time through the intensity of the reflected light to det...
