Four of the preferred embodiment of the present invention
The foregoing description with reference to one of Fig. 3 preferred embodiment of the present invention and two diopter functional arrangement, three diopter functional arrangements of Fig. 4 preferred embodiment of the present invention, Fig. 5 sharpness functional arrangement be described, below in conjunction with Fig. 6 eyes imaging schematic diagram this preferred embodiment is described in detail.
In this preferred embodiment, central circle of good definition 1 is selected concavees lens for use, and confusion region 3 is selected convex lens for use on every side.Central authorities choose patient's the best optometry number of degrees in circle of good definition 1, and the number of degrees chosen of confusion region 3 are advisable more than the diopter 3.00D of the diopter of confusion region 3 greater than central circle of good definition 1 on every side greater than the best optometry number of degrees on every side.
Shown in Fig. 6 eyes imaging schematic diagram, if the diopter of central area is got patient's best diopter, dioptric zone of transition 2, confusion region 3 is greater than best diopter on every side, like this, can be divided into transition imaging area 61, blur-free imaging district 62, fuzzy 63 3 imaging areas of imaging area in the eyeball with the people.The amphiblestroid zone of representative, blur-free imaging district 62 forms image from the light of central circle of good definition 1 in this zone, makes the people see distinct image; Transition imaging area 61 representative is from the nearer zone of retina, at this regional imaging, makes people seem slightly show fuzzy at this regional image from the image of dioptric zone of transition 2; Fuzzy imaging area 63 representatives are from retina zone far away, and the image of confusion region 3 makes the people seem fuzzyyer at this regional imaging at this regional image on every side, can only see the profile of object.
Wear patient of the present invention and can clearly be seen target object in central circle of good definition 1, and in dioptric zone of transition 2, confusion region 3 sees on every side is a target object that becomes more and more fuzzyyer, therefore effective field of view has diminished, and social anxiety disorder patient's psychological stress is eased.
Also can adopt combination to join the method for mirror when noncontact mirror central authorities circle of good definition not simultaneously with confusion region lens type on every side, promptly the wearer wears a secondary common contact lense and a copy simultaneously and invents described noncontact mirror.Such as central circle of good definition is concavees lens, when the confusion region is convex lens, can make the contact lense number of degrees be just (non-gradual change) on every side, and the whole noncontact mirror number of degrees are negative (gradual change).This be equivalent to the described noncontact mirror eyeglass number of degrees all deduct one fixing on the occasion of, make the eyeglass number of degrees totally for negative.
Five of the preferred embodiment of the present invention
Also can carry out subregion to these lens, make the transmittance or the transparency difference of the zones of different of lens, reach the purpose of lens being carried out partition by adding impurity in the eyeglass zones of different.
This preferred embodiment five in, with reference to shown in Figure 1, the diopter of central circle of good definition 1 is the normal number of degrees, this part does not add impurity; The peripheral region can reduce the transmittance of this part or reduce the transparency of this part by adding non-homogeneous impurity by adding uniform impurity.Wherein, add even foreign pigment and be equivalent to reduce the transmittance of this part, just reduce brightness, just have positive effect when dye levels is higher by the imaging of this zonal ray to eyeglass dyeing; When adding non-homogeneous impurity, can reduce the transmittance of this part on the one hand, can cause light scatter on the other hand, reduce transparency, make by this zonal ray imaging to thicken.
In this preferred embodiment, the transmittance and the transparency of central circle of good definition 1 are the highest, and therefore in this zone, the user can see target object the most clearly; Dioptric zone of transition 2 and on every side the transmittance of confusion region 3 or transparency reduce with respect to central circle of good definition 1, so the sharpness of the object seen of user reduces than circle of good definition 1, reached the purpose of reduced field of view.
Wear patient of the present invention and can clearly be seen target object in central circle of good definition 1, and in dioptric zone of transition 2, confusion region 3 sees on every side is a target object that becomes more and more fuzzyyer, therefore effective field of view has diminished, and social anxiety disorder patient's psychological stress is eased.
If adopt even impurity is added when reducing the way of visible light transmissivity in the contact lense confusion region, be necessary to make a distinction with common aperture contact lenses, common pinhole imaging system contact lenses (being used for the treatment of adolescent myopia) peripheral region sharpness is higher, otherwise the obvious reduced field of view of meeting does not meet the near-sighted needs of treatment.In addition, just change over the brightness of picture by dyeing, deformation does not take place in imaging.In view of this two aspects reason, I think that common pinhole imaging system contact lenses can not satisfy the needs that cause wearer's effective field of view to diminish.If select haptic lens for use, the diameter of central circle of good definition 1 is less than 3mm, and dioptric zone of transition 2, the visible light transmissivity of confusion region 3 unit areas should be chosen less than 1/3 of central circle of good definition and be advisable on every side.If adopt when adding non-homogeneous impurity reduction peripheral region transparency way, can keep whole eyeglass colourless basically.
In the various embodiments described above, the size of central circle of good definition 1 and dioptric zone of transition 2, the blur level of confusion region 3 should be decided according to wearer's (patient) concrete conditions such as psychological condition on every side.In general, when the social anxiety degree of wearer was higher, it was less to join central circle of good definition 1, dioptric zone of transition 2, the bigger eyeglass of confusion region 3 blur leveles on every side.And, can progressively strengthen the area of central circle of good definition 1 along with the alleviation of the social anxiety of wearer, reduce the blur level of confusion region, up to the same with common spectacles.
