The invention discloses a gamification and memory amblyopia training method and system. The training method includes: displaying a noise interference background and an amblyopia training target optotype with a preset orientation on a training page; randomly displaying a preset number of amblyopia training optotypes with different orientations on the noise interference background; monitoring a trigger trajectory on the training page in real time, and judging whether the trigger trajectory crosses the randomly displayed amblyopia training optotype or not; increasing a score if the crossed amblyopia training optotype and the amblyopia training target optotype have the same orientation, and decreasing the score if the orientations are different; and entering a higher next level when the statistical score reaches a preset score each time, wherein the interference of the background noise is increased, and the display number and display frequency of the amblyopia training optotypes are increased and the sizes of the same are reduced. Through the technical scheme of the present invention, various visual functions and visual skills of the patient are improved, the vision of an amblyopic eyeis improved, and meanwhile, richness, interest and effectiveness are also increased.

The invention provides a VR training system for amblyopia patients, including a server, a mobile terminal and VR glasses. The server is integrated with an output unit, an input unit, a database, a data processing platform and a wireless transceiver. A training method comprises the following steps: inputting of basic information, information receiving, resource matching, resource receiving, resource presenting and visual training.

The embodiment of the invention discloses an amblyopia visual aid based on waveguide display, which comprises a camera system, an input device, a circuit control system, a waveguide display system andshielding pieces. The amblyopia visual aid provided by the embodiment of the invention relates to the field of waveguide display and the field of electronic visual aid technologies, combines an optical waveguide display technology, a reality enhancement technology, an electronic amplification technology and an image processing technology and adopts waveguide transmission display. Different from similar visual aid products adopting closed display, the amblyopia visual aid does not result in the symptoms such as dizziness and nausea caused by visual-somatosensory conflicts due to the closed vision. The amblyopia visual aid provided by the embodiment of the invention is compact, light, small in size, more similar to ordinary sunglasses and not obvious when being worn, does not cause specialattention and can better help the amblyopic people to observe the things around.

The invention provides an amblyopia training reader based on separated vision control and an adjusting and setting method of the amblyopia training reader. An input module is used for loading an electronic document; a document processing module is used for processing the loaded electronic document into word contents and a left vision page and a right vision page of a same format; an adjusting andsetting module is used for adjusting and setting distinguishing degrees of contents in the left vision page and the right vision page respectively, and the distinguishing degree of the contents in a page corresponding to a healthy eye is lower than that of the content in a page corresponding to an amblyopia eye; and vision separation equipment is used for transmitting the left vision page and theright vision page to a left eye and a right eye respectively. Contents seen by the healthy eye are hard to distinguish, contents seen by the amblyopia eye are easy to distinguish, then the amblyopia eye has more distinguishing opportunities at the moment, and thus an effect of improving visual power can be achieved. As seen contents are loaded into an electronic book by a patient by self accordingto demands, vision training is combined with daily reading, and extra time of the patient is not occupied.

The invention discloses a remotely-controlled visual chart (capable of treating amblyopia and low myopia) with a box, which is characterized in that detection symbols refer to eight openings (upper, lower, left, right, upper-left, lower-left, upper-right and lower-right), eight ensiform remotely-controlled receiving type indicating lamps (at upper, lower, left, right, upper-left, lower-left, upper-right and lower-right) are arranged above a box body, the indicating lamps have eight colors, a remotely-controlled transmitting pedal (divided into upper, lower, left, right, upper-left, lower-left, upper-right and lower-right parts) is correspondingly arranged, the pedal has corresponding eight colors, and the center of the remotely-controlled pedal is provided with a device which can carry out 360-degree rotation. The top of the box body is provided with an inserting slot for replacing visual charts, and 3-5 pieces of symbol vision boards with different detection directions are stored. The remotely-controlled visual chart (capable of treating the amblyopia and the low myopia) with the box can be used for carrying out the ordinary vision detection, and also can carry out the normal vision detection on deaf-mute children, and in the process of vision detection, a tested person is not required to talk but just steps on corresponding arrows while seeing the opening directions or colors of the detection symbols of the visual chart, then the indicating lamps above the visual chart are turned on, so that through cooperating with a vision correction method (application number: 201110270610. X) invented by the inventor of the invention previously, a person with the amblyopia and the low myopia can achieve or are close to be at a condition of normal vision in a short time.
