S6: picking up counting, judge whether to reach stimulation time T, is execution in step S7 then, otherwise continues execution in step S5;
Step S7: stimulating exercise finishes, and display screen recovers initial setting up.
This utility model provides a kind of thorn lasing light emitter regulatable specific implementation method:
According to there being the inconsistent inhibition of degree of depth position on the amblyopia eyes retina, this utility model provides regional stimulation by regulating and control corresponding display screen, effectively improves the vision of amblyopia eye.
For example: when needs stimulated macular area, described central stimulation unit got final product so only need adopt a central display screen to stimulate at the macula retinae district, with the long wavelength of 580nm to 780nm, to stimulate human eye cone cell sensitivity; At all side screens (screen except that central display screen), then increase the sensitivity in peripheral retinal region (zone except that macular area) to the thorn lasing light emitter of the short wavelength of 580nm and different brightness with 380nm.
To the amblyopia patient of " paracentral fixation " is arranged, screen at corresponding " paracentral fixation point ", adopt brightness " paracentral fixation point " to be suppressed,, stimulate to the long wavelength of 780nm with 580nm at the screen of corresponding macular area greater than the high-strength light of 100LUX; Final purpose is the different stimulated means that can provide by continuous adjustment zones of different screen, comes balance retina allomeric function level, recovers visual capacity comprehensively.
Common amblyopia patient watches central screen attentively, and the middle section screen sends the long wavelength to stimulate, and all side screens send the stimulation of short wavelength and different brightness; At the amblyopia patient of " paracentral fixation ", with high-strength light " paracentral fixation " point is carried out part (different amblyopia patients' paracentral fixation point position all can be different) and suppress, other regional screens are strengthened stimulating with low-intensity light; The training later stage can constantly be adjusted the different stimulated means that the zones of different screen can provide, balance retina W-response.
This utility model also provides another kind of thorn lasing light emitter regulatable specific implementation method:
According to the characteristics of the amphiblestroid zones of different of myopia, the screen of zones of different can be simulated and adjust to this utility model, and amphiblestroid different parts is produced multi-form defocus signal to stimulate.
For example: 20 degree are moved forward 0 ± 20mm with inner region screen integral body, can form the myopia focus at human eye retina's central area; Regional screen integral body beyond 20 degree is moved 0 ± 20mm backward, can form the hypermetropia focus, otherwise screen moves backward and can form the myopia focus at peripheral retinal region in the human eye retina surrounding zone.By moving forward and backward the screen position of central area/surrounding zone, can form myopia/hypermetropia defocus signal stimulation at human eye retina's central area and surrounding zone.Also can reach or the auxiliary purpose that bathomorphic vision is provided in addition by changing the length (for example the long wavelength can form the hypermetropia out of focus, and the short wavelength can form the myopia out of focus) of central area/wavelength that the surrounding zone screen sends.
Common myopia patient watches central screen attentively, by reach central area screen (the surrounding zone screen is motionless), forms the myopia defocus signal at human eye retina's central area, keeps 2 minutes; The central area screen resets then, and reach surrounding zone screen forms the myopia defocus signal in the human eye retina surrounding zone, keeps 2 minutes; Next the whole reach of central area/surrounding zone screen forms consistent myopia defocus signal in human eye retina central authorities/surrounding zone, keeps 2 minutes; Then central area/surrounding zone screen is constantly moved in position and between anterior displacement, forming human eye retina central authorities/peripheral alternative myopia out of focus stimulates, kept 4 minutes.The near-sighted number of degrees are deepened patient faster, can in the above-mentioned course of treatment, increase the variation that stimulates wavelength of light, to strengthen of the stimulation of myopia out of focus to retinal centre/periphery, for example when moving forward, screen adds short wavelength light, can strengthen the stimulus intensity of myopia out of focus.
This utility model compared with prior art, has following advantage: this utility model device, plan is built the regulatable visual exercise thorn of cover laser source device, utilization is to the control of factors such as image space, wavelength of light, carry out targetedly human eye zones of different retinal area sexual stimulus, reach auxiliary eyeball development (rectification amblyopia), promote the function of retina neural signal transmission (pre-myopia prevention), reach the assosting effect that promotes that visual performance is grown.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of this utility model claims.
