Embodiment
In order to describe the technical solution of the utility model in detail, below in conjunction with the accompanying drawing of the utility model embodiment, clear, complete description is carried out to the technical scheme of the utility model embodiment.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
Please refer to Fig. 1 ~ 3, the eye imaging principle myopia long sight origin cause of formation of the present utility model and rectification apparatus for demonstrating, comprise the scale 1 for simulated range distance, for simulating the light source 2 of object, eyeball phantom 3, and for simulating the concavees lens 4 and convex lens 5 of wearing glasses and correcting.Light source 2 is placed in the distant place or nearby of scale 1, is positioned at a distance or closely with analogies body, such as: the left end of scale 1 be at a distance, the centre of scale 1 is for nearby.Light source 2 can be installed on scale 1 for clamping slidably, to facilitate the movement of light source 2.Concavees lens 4 and convex lens 5 also can be installed on scale 1 for clamping slidably, when not using, can take off from scale 1.Eyeball phantom 3 is fixed on the initiating terminal of scale 1, to simulate the eyes of human body, such as: the right-hand member of scale 1 is initiating terminal.Eyeball phantom 3 can be mounted on scale 1 by means such as screw, glue stickups.Be provided with in eyeball phantom 3 for simulating lenticular lens combination 31, for simulating amphiblestroid imageable sheet 32 (can make for the scraps of paper).Lens combination 31 comprises front lens 311, rear lens 312, front lens 311 is fixed on the front side of eyeball phantom 3, imageable sheet 32 is fixed on the rear side of eyeball phantom 3, rear lens 312 can be installed on the center of eyeball phantom 3 by electronic slide unit 33 with moving horizontally, and rear lens 312 is between front lens 311 and imageable sheet 32, like this, by rear lens 312 forward or movement backward change distance between front lens 311 and rear lens 312, and simulate crystalline lens and flatten or become convex.
Preferably, the utility model also comprises the slide unit telepilot 34 for remote control rear lens 312 movement, to move forward or backward conveniently by slide unit telepilot 34 remote control rear lens 312; Light source 2 is LED, and LED is energy-conservation, low in energy consumption, and LED can be made into word or pattern, as " A " in figure, makes demonstration vivider.
The utility model is in eye imaging principle demonstration: when 1, needing demonstration to see distant objects, first light source 2 be placed in the distant place of scale 1 and simulate object a long way off, then moved from back to front by slide unit telepilot 34 remote-controlled movement rear lens 312, like this, students' union find rear lens 312 be positioned at comparatively front position time (as shown in Figure 4), namely the distance of front lens 311 and rear lens 312 is less, imaging on imageable sheet 32 is comparatively clear, thus make student know " when seeing at a distance; crystalline lens flattens; refractive power dies down, become on the retina clearly as "; When 2, needing demonstration to see near objects, what first light source 2 is placed in scale 1 simulates object on hand nearby, then moved from front to back by slide unit telepilot 34 remote-controlled movement rear lens 312, like this, students' union find rear lens 312 be positioned at comparatively after position time (as shown in Figure 5), namely the distance of front lens 311 and rear lens 312 is larger, imaging on imageable sheet 32 is comparatively clear, thus make student know " when seeing nearby; crystalline lens become convex; refractive power grow, become on the retina clearly as ".So, demonstration conclusion can be drawn: eyes are seen clearly at a distance and near objects by regulating lenticular plano-convex degree.
The utility model is in the demonstration of the myopia origin cause of formation: what first light source 2 is placed in scale 1 simulates object on hand nearby, and mobile rear lens 312 is positioned at position comparatively, make the imaging on imageable sheet 32 comparatively clear, then light source 2 be placed in the distant place of scale 1 and simulate object a long way off, and rear lens 312 remains in position motionless (as shown in Figure 6) comparatively, now, students' union finds that the imaging on imageable sheet 32 is comparatively fuzzy, thus make student know the bathomorphic origin cause of formation, i.e. long-time close eye, crystalline lens is in more convex state for a long time, when seeing at a distance, crystalline lens should flatten, but regulate and do not come, lose regulating power, be imaged on before retina, object at a distance has not just seen.
The utility model is corrected in demonstration in myopia: first complete above-mentioned myopia origin cause of formation demonstration, device is made to be in the state shown in Fig. 6, then concavees lens 4 are placed in the front (as shown in Figure 7) of front lens 311, now, it is clear that students' union finds that the imaging on imageable sheet 32 becomes, thus student is known " myopia is corrected defects of vision by wearing concavees lens 4 ".
The utility model is in the demonstration of the farsightedness origin cause of formation: first light source 2 is placed in the distant place of scale 1 and simulates object a long way off, and mobile rear lens 312 is positioned at comparatively front position, make the imaging on imageable sheet 32 comparatively clear, what then light source 2 is placed in scale 1 simulates object on hand nearby, and rear lens 312 remains in motionless compared with front position (as shown in Figure 8), now, students' union finds that the imaging on imageable sheet 32 is comparatively fuzzy, thus farsightedness (is commonly called as to make student know, presbyopia) the origin cause of formation, namely old people is along with the degeneration of physical function, crystalline lens is in more flat state, object at a distance can be seen clearly, but when seeing nearby, crystalline lens should become convex, but regulate and do not come, lose regulating power, be imaged on after retina, object nearby has not just seen.
The utility model is corrected in demonstration in farsightedness: first complete above-mentioned farsightedness origin cause of formation demonstration, device is made to be in the state shown in Fig. 8, then convex lens 5 are placed in the front (as shown in Figure 9) of front lens 311, now, it is clear that students' union finds that the imaging on imageable sheet 32 becomes, thus student is known " farsightedness is corrected defects of vision by wearing convex lens 5 ".
In sum, the utility model dynamic realizes eye imaging principle demonstration, myopia and the presbyopic origin cause of formation and corrects demonstration, makes student's easy understand, and, having the advantages such as simple to operate, clear and intuitive, teaching demonstration is strong, is a good equipment of aided education.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement, all belong to protection domain of the present utility model.
