TECHNICAL FIELD
[0001] The utility model belongs to visual correction technical field, concretely relates to a novel far image reading and writing platform. BACKGROUND
[0002] As a common ametropia, myopia can be well corrected by some optical correction means (such as frame glasses, corneal contact lenses, etc.) or surgery. Except that wearing glasses will affect appearance, it does not seem to affect the daily life of patients. However, high or super high myopia can cause a series of serious ophthalmic complications such as retinal detachment, macular hemorrhage, posterior scleral staphyloma, thereby impairing the visual function of patients. For patients with high myopia, the incidence of open-angle glaucoma is also significantly higher than that of ordinary people. Once myopia occurs in adolescent patients, the myopia degree will continue to increase. In view of this, it has important research significance to study how to control the progress speed of adolescent myopia and reduce the incidence of high or super high myopia, thereby reducing the blindness and disability rate of high myopia complications.

[0020] The utility model will be described in further detail below in combination with embodiments.
[0021] As Figure 1 And Figure 2 The utility model provides a specific embodiment 1 of a novel far image reading and writing platform:
[0022] A novel far image reading and writing platform, including support 1, the support 1 is provided with reading equipment placing table 2, the top of support 1 is installed with box 3, the box 3 is located directly above reading equipment placing table 2, and the box 3, support 1 and reading equipment placing table 2 are integrally formed structure, the integrally formed structure can make the whole equipment structure more firm, and reading equipment placing table 2 is used for placing books or tablet computers etc., and the bottom surface and the front surface of the box 3 are transparent, which can be understood as being empty at the bottom surface and the front surface of the box 3, or transparent glass plates can be arranged;
[0023] A half-mirror 4 is installed in the box 3, the half-mirror 4 is set to be inclined backward by 45±15 °, and one side of the half-mirror 4 coated with a wideband half-mirror film faces downward, and the other side coated with a wideband antireflection film or without coating faces upward and forward;
[0024] A Fresnel lens 5 is installed in the box 3, the Fresnel lens 5 is arranged along the horizontal direction, the Fresnel lens 5 is located above the half-mirror 4, and a black shading layer is arranged in the central part of the Fresnel lens 5;
[0025] A concave mirror 6 is also installed in the box 3, the concave mirror 6 is located behind the half-mirror 4, and the concave surface of the concave mirror 6 faces the half-mirror 4.
[0026] A ring-shaped illumination light source 7 is installed at the bottom surface of the box 3, the illumination light source 7 is arranged between the half-mirror 4 and the reading equipment placing table 2, preferably, the illumination light source 7 is a ring-shaped LED lamp, the LED lamp irradiates the reading equipment placing table 2 downward, the illumination intensity of the LED lamp is 500-20000 Lux, the LED lamp can enhance the illumination brightness and the entrance pupil brightness, effectively stimulates the retinal dopamine secretion, thereby preventing or delaying the occurrence and progression of myopia, and the LED lamp is powered by a direct current power supply, thereby removing the frequency flicker of ordinary table lamps, effectively reducing visual fatigue, thereby preventing or delaying the occurrence and progression of myopia.
[0027] When using the new far reading and writing platform of the embodiment, the book 9 can be placed on the reading device placing table 2, and then the illumination light source 7 is turned on, the light emitted by the LED lamp is directly irradiated downward on the book 9, and uniform illumination is provided; after the light on the book 9 is illuminated, the light is emitted in all directions, part of the light is irradiated upward to the half reflective and half transmitting lens 4 arranged at an angle of 45°, the half reflective and half transmitting lens 4 reflects part of the light, and another part of the light is allowed to pass through, the light reflected by the half reflective and half transmitting lens 4 reaches the concave mirror 6 located behind the half reflective and half transmitting lens 4, the concave mirror 6 receives the light and reflects the light back to the direction of the half reflective and half transmitting lens 4, the light passes through the half reflective and half transmitting lens 4 again and enters the eyes of the reader, so that a virtual reading image is formed, which looks like being projected from a distance (for example, 4 meters away) in front of the eyes of the reader, the near distance work is converted into far distance work, the far distance reading and writing effect is realized, the myopia occurrence and progression can be greatly reduced, and through the prescription of glasses, the negative defocus can be adjusted to positive defocus, thereby preventing or delaying the occurrence and progression of myopia.
