The specific embodiment
As shown in fig. 1, be a preferred embodiment of the present invention, comprise branch glasses, display device, input block and matching control unit.Described minute glasses is the eyeglass that two eyeglasses are respectively different colours.Described display device shows transparent synergetic stimulus modelity image and derepression image, described stimulus modelity image comprises bar grid image, cross-hatch pattern picture, concentric circle diagram picture, compass table images etc., and derepression image can adopt the display image of some training recreation.
Concrete use is as follows: select the right and left eyes of oneself to correct defects of vision when the patient trains earlier, after the input block input of this vision value by realizations such as keyboards, pass to matching control unit, whether matching control unit is judged at first that patient's eyes are corrected defects of vision and be there are differences, as there is not difference then not generate the stimulus modelity image, directly load the image of derepression training recreation, the control display device shows; As there are differences, to judge also then which eye is for being suppressed eye, and according to the mode of wearing of dichoptic viewing glasses right red and left green, decide the color of the stimulus modelity that is complementary with it, so that the stimulus signal of stimulus modelity can only be received by being suppressed eye, also to obtain parameter value simultaneously with corresponding spatial frequency of vision and temporal frequency, and this parameter value is passed to the generator of stimulus modelity, after finishing above-mentioned coupling work, system begins to load the training recreation and has stimulus modelity image with corresponding spatial frequency of patient's vision and temporal frequency parameter value.
Two forms of described minute view apparatus adopt the eyeglass of two different colors respectively, and the colour of lens of a side of described filtration stimulus modelity image is consistent with the wherein a kind of color in the stimulus modelity image.For example, adopt and only contain the interesting derepression training recreation of enriching of 3 kinds of colors of pink colour, redness and blueness (or purple, redness and blueness), as dynamic derepression pictorial display, these recreation all are to be the background background color with pink colour (purple), with red, blueness is the color of game graph, can be used in combination traditional flicker stimulus method and trapping, turnover method, these dynamic stimulus methods of lateral movement method in these recreation, recreation simultaneously is provided with action prompt sound and promotion and demotion.
Adopt Hydrargyri Oxydum Rubrum (purple) alternate or alternate bar grid, gridiron pattern, the concentric circular of blue powder (royal purple), the dynamic stimulus modelity image of these of compass lattice, and the spatial frequency of these stimulus modelities (being color interval distribute spacing or dense degree) is divided into several grades from low to high, and temporal frequency (be the moving of stimulus modelity image, rotate, the rate of change of upset) also is from slowly to being divided into the correcting defects of vision to corresponding of several grades and patient's inferior position eye soon.For example spatial frequency and temporal frequency are according to correcting defects of vision and can being divided into 13 grades more than or equal to 1.0 by 0.1,0.12,0.15,0.2,0.25,0.3,0.4,0.5,0.6,0.7,0.8,0.9.
In matching control unit, above derepression training is played and bar grid, gridiron pattern, concentric circular, the mutually transparent stack of these stimulus modelities of compass lattice, containing recreation and the pictorial display of stimulus modelity after the stack simultaneously in display device, the patient also can control demonstration voluntarily or hide bar grid, gridiron pattern, concentric circular, these stimulus modelities of compass lattice.System can be in the following way to the control of stimulus modelity: the training time is 15 minutes each time in system, occur in the following order at several stimulus modelities in these 15 minutes: the operation of bar grid stimulus modelity is after 4 minutes, gridiron pattern stimulus modelity 4 minutes brings into operation, bring into operation again afterwards concentric circular stimulus modelity 4 minutes moves compass lattice stimulus modelity 3 minutes at last.The patient can change derepression training game item at any time in the training process, or the control stimulus modelity is demonstration or hiding.
The patient puts on the dichoptic viewing device during training, as what wear is red green minute glasses, then red eyeglass is worn over right eye, and green len is worn on the left eye.When the patient there are differences because of binocular vision, just can allow dominant eye and two of inferior position eyes see eyes derepression image simultaneously like this, carry out the training of derepression training recreation by the dichoptic viewing device; And the eyeglass of dominant eye (the supposition right eye is a dominant eye, use red eyeglass) filtered the respective color in the stimulus modelity image, display background color, then (the supposition left eye is the inferior position eye to corresponding color to the inferior position eye by superposeing with the complementary eyeglass of dominant eye colour of lens, use green len), the stimulus modelity image is strengthened, outside the stimulus signal of accepting derepression training recreation, the also stimulation of the stimulus modelity image of accepting extraly, strengthened stimulation to the inferior position eye, help the raising of inferior position eye vision in this way, help removing the inhibition of dominant eye to the inferior position eye, allow eyes reach balance as early as possible, thereby can help the patient to slough simple eye inhibition fast, rebulid binocular visual function.
The present invention compares the present invention with the binocular visual function derepression training that traditional application synoptophore carries out and has the following advantages: utilize and divide a view apparatus, filter the stimulus modelity image in dominant eye one side, the stimulus modelity image directly acted on be suppressed eye, more effective than traditional simple flicker stimulus method, trapping, turnover method, lateral movement method, help the inferior position fast derepression of being sharp-eyed.Image in the system utilizes the dichoptic viewing device allow every soon to different separately images after display device (as display) is gone up demonstration, utilize specific stimulus modelity in the system stimulate eyes separately macula lutea and around the retina photoreceptor cell make it excited, remove and suppress, set up normal binocular visual function.When the patient there are differences because of binocular vision, by the dichoptic viewing device by dominant eye and two training of carrying out binocular visual function simultaneously of inferior position eye, the inferior position eye is then also accepted the stimulation of stimulus modelity specific in the system extraly outside the stimulus signal of accepting the binocular visual function training by the dichoptic viewing device, reinforcement is to the stimulation of inferior position eye, help the raising of inferior position eye vision in this way, help removing the inhibition of dominant eye to the inferior position eye, allow eyes reach balance as early as possible, thereby can help amblyopia patient and stravismus patient to slough simple eye inhibition fast, rebulid binocular visual function.
In addition, derepression image adopts abundant in content, simple to operate trivial games, also can be with the picture in the replacing recreation at any time of child's hobby, training vivid and interesting in the training.By system of the present invention, action prompt sound and the background music that is imbued with sense of rhythm can also be set, respond to remind for the correctness of trainer's action, human computer conversation's property is strong, and trainer's compliance is good, and property of participation is strong.
More than system for training dichoptic viewing provided by the present invention is described in detail, used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
