Embodiment 1

[0015] Embodiment 1, adjust the height of the 1 bracket by turning the 5 adjustment knob, so that the user must sit upright to view the visual mark through the 4 eyepiece hole on the 10 optical system box; turn the 6 adjustment knob to adjust the position of the 2 primary reflector The angle is to limit the field of view, so that the user must extend the arm as far as possible to hold the book and the pen; turn the 7 adjustment knob to adjust the distance between the 3 secondary reflector and the 2 primary reflector, in the case of being able to see clearly without fatigue Extend the distance as far as possible, the total length of the optical path L=L1+L2+L3 will be far greater than 33 cm, changing the distance from near to far, so that the eyes will not experience myopia fatigue; change the height of the 3 secondary reflectors by rotating the 8 adjustment knob Or angle, so that the user can get the best possible visual experience.

[0016] To fix the visual target, the user ...

Embodiment 2

[0017] Embodiment 2 is mainly to prevent the effect of myopia prevention and control from being affected by the user's random adjustment of the position of the reflector or the distance between the mirrors. The reflector is fixed at a suitable position so that it cannot be adjusted during use. Turn the 5 adjustment knob to adjust the height of the 1 bracket. The user must sit upright to view the target through the 4 eyepieces on the 10 optical system box; The total length L=L1+L2+L3 is used to specially prepare eyepieces to prevent over-correction. It is advisable to minimize excessive myopia fatigue in the eyes, prevent myopia, and slow down the development of myopia. This can also achieve the same myopia prevention and control effect as example one.

Embodiment 3

[0018] Embodiment 3, adjust the height of the 1 bracket by turning the 5 adjustment knob, so that the user must sit upright to check the visual mark through the 4 eyepiece hole on the 10 optical system box; turn the 6 adjustment knob to adjust the position of the 2 camera or Angle to limit the field of view, so that the user must extend the arm as much as possible to hold the book and hold the pen; turn the 7 adjustment knob to adjust the distance between the 3 monitor and the 4 eyepiece hole, and stretch it as far as possible without fatigue The distance, the total length of the optical path L=L3 will be far greater than 33 centimeters, and the distance will be changed from near to far, so that the eyes will not experience excessive myopia fatigue; the height or angle of the 3 display can be changed by rotating the 8 adjustment knob, so that the user can get as much as possible Good visual experience.

Abstract

The invention provides a posture correcting eye-protection instrument, which relates to the field of prevention and control of myopia, wherein, the posture correcting eye-protection instrument is mainly used for developing correct reading and writing posture habits of students, for example, the students stretch arms when in reading, writing and looking and try to keep a long distance when clear reading can be ensured; the posture correcting eye-protection instrument is suitable for people with different heights to change the short viewing distance to the long viewing distance in various close range operation occasions such as reading, writing, television program watching through a computer and the like; and the posture correcting eye-protection instrument can prevent and control occurrence and development of eye myopia. The posture correcting eye-protection instrument comprises a bracket and an optical system box internally comprising an objective image collection display device, wherein, the objective image collection device that directly aims at a sighting target and an eyepiece hole are positioned on the same side direction of the optical system box. The posture correcting eye-protection instrument can provide the visual experience identical to direct viewing, and leads youngsters to be willing to use continuously; and the posture correcting eye-protection instrument can prevent crookback, can prevent spinal curvature, can prevent myopia occurrence, and can slow down the deepening the development of myopia.
