Embodiment 1

[0036] Example 1, such as figure 1 As shown, the amblyopia training reader based on split vision control provided by this embodiment includes an input module, a document processing module, a setting module and a split vision device connected in sequence; the input module is used to load electronic documents, The document processing module is used to process the loaded electronic documents into left-view pages and right-view pages with the same text content and format. The adjustment module is used to adjust the parameters in the left-view pages and right-view pages respectively, so that The clarity of the page is lower than that of the amblyopic eye; the split-view device is used for split-view display, and transmits the left-view page and right-view page to the left eye and the right eye respectively. In this application, when comparing the vision of the left and right eyes, the eye with better vision is the healthy eye, and the eye with poorer vision is the weak eye.

[003...

Embodiment 2

[0052] In this embodiment, the left eye is a healthy eye, and the right eye is an amblyopic eye, and the adjustment module adopts the method of adjusting the background brightness. Such as Figure 5 As shown, reduce the background brightness of the left-view page, and adjust the background brightness parameter to 40%. The background brightness of the right-view page is adjusted to 75%; the text displayed on the left-view page is difficult to recognize due to the low background brightness, and the text displayed on the right-view page is easier to recognize due to the high background brightness. The left-view page and the right-view page are transmitted to the left eye and the right eye respectively through the split-view device. Actively watch to achieve the effect of training and optimizing the right eye.

[0053] At the same time, the deletion module randomly deletes single or multiple phrases or short sentences in the left-view page.

[0054] If the adjustment module adj...

Embodiment 3

[0058] In this embodiment, the left eye is the healthy eye, and the right eye is the amblyopic eye, and the adjustment module adopts the method of adjusting the degree of blur, where the degree of blur is Gaussian blur. Such as Image 6 As shown, if the Gaussian blur of the left-view page is reduced and the Gaussian blur of the right-view page remains unchanged, the text displayed on the left-view page is difficult to recognize because of the low blur, and the text displayed on the right-view page is easier to recognize because of the high blur. identify. The left-view page and the right-view page are transmitted to the left eye and the right eye respectively through the split-view device. Actively watch to achieve the effect of training and optimizing the right eye.

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of vision training equipment, in particular to a visually impaired training reader based on split vision control and a setting method thereof. Background technique [0002] Amblyopia refers to the loss of best-corrected visual acuity in one or both eyes due to abnormal visual stimulation during the critical period of visual development without organic lesions. Patients with amblyopia not only show low vision, but more seriously, because of the abnormal correspondence of retinal corresponding points, the binocular vision function is abnormal, manifested as binocular simultaneous vision function, collection and separation function, and stereo vision function are weak or absent. [0003] Patent CN201710183726.7 is an amblyopia training system applied by West China Hospital of Sichuan University on March 24, 2017. It discloses a binocular balance point measurement module and a binocular split vision control modu...
