Abstract
The utility model relates to a visual acuity health care therapeutic instrument which is a medical care instrument and is mainly used for eyesight health care and nearsightedness treatment. The utility model comprises an eyepiece, an objective and connecting and fixing devices thereof, wherein the objective is a concave lens, and the eyepiece is a convex lens, or a plano lens, or a concave lens. The utility model also comprises a bracket and lighting sources for reading. When the visual acuity health care therapeutic instrument is used for reading, a book can be imaged to a relatively long distance to cause crystalline lenses to be adjusted to a relatively flat state so that eyes are not easy to fatigue, the effects of the eyesight health care and the nearsightedness treatment are favorable, and the use is convenient.
Description
This utility model relates to a kind of medical health Instrument, particularly a kind of eyesight health therapeutic apparatus.
Have a kind of reading glasses of wearing to see far away and be equipped with the apparatus for treating myopia of electricity irritation in the market, image is clear inadequately because the myopia patient wears presbyopic glasses when seeing at a distance, and therapeutic effect is not ideal enough.The myopia patient who has puts on the presbyopic glasses reading, and eyes are easy to fatigue, can not wear long-time reading, and are not good to the care treatment effect of myopia.
The purpose of this utility model provides a kind of eyesight health therapeutic apparatus, can treat myopia with it, prevents visual deterioration, and quick result, effect are comparatively obvious, and be easy to use.
Myopia is read a book too much often, and because of reading in-plant book, crystalline lens is adjusted to more protruding state, and time length is easy to generate fatigue, loses regulating power gradually, and crystalline lens is adjusted to the ability drop of seeing far beyond flat-shaped attitude, produces myopia.And myopia wears behind the near-sighted glasses that the imaging of Book of Records near-sighted glasses is to nearer distance, and crystalline lens is regulated more protrudingly.
This utility model is that eyes (or the back that puts on one's glasses) see that by the eyepiece object lens reading thing reads a book, object lens are concavees lens, eyepiece is selected to see or to recognize the dioptric lens than the advanced algebra value of reading the thing writing clearly, crystalline lens is adjusted to more flat-shaped attitude during the eyes reading, be not easy fatigue, to vision care, it is better, easy to use to treat near-sighted effect.
Eyesight health therapeutic apparatus of the present utility model comprises the eyepiece object lens and is connected and fixed device, and object lens are concavees lens, and eyepiece is convex lens or goggles or recessed transaction, comprises the eyepiece object lens are fixedly propped the support that can place the reading thing below object lens.
Described eyepiece object lens can be one or a pair of respectively.
Described eyesight health therapeutic apparatus also can comprise the light source of reading the object location illumination to placing.
Described eyesight health therapeutic apparatus, described eyepiece can be changed.
Below in conjunction with accompanying drawing and preferred embodiment structure of the present utility model, feature and purpose are described further.
Fig. 1, Fig. 2 are the structural representations of two preferred embodiments of this utility model.
With reference to Fig. 1, present embodiment comprises eyepiece 1 object lens 2 and is connected and fixed device 3, and object lens are concavees lens, and eyepiece is convex lens or goggles or concavees lens, comprises the eyepiece object lens are fixedly propped the support 4 that can place the reading thing below object lens.Present embodiment can also comprise the light source 5 of reading the object location illumination to placing, and light source 5 can be halogen tungsten lamp or electric filament lamp or fluorescent lamp, and light source 5 is preferable when having the halogen tungsten lamp of cold light reflector.The eyepiece of present embodiment can be changed; The eyepiece of present embodiment can be a pair of, and object lens can be one.The preferable parameter of present embodiment is for example: eyepiece focal length+25 centimetre, diopter+400 degree, objective focal length-16.7 centimetre, distance is 16 centimetres between the eyepiece object lens, when eyes are read book apart from 30 centimetres on eyepiece by the eyepiece object lens, Book of Records cross the imaging of object lens eyepiece to apart from 450 centimetres on eyepiece and resemble and book at the homonymy of eyepiece.
With reference to Fig. 2, present embodiment comprises eyepiece 1 ' object lens 2 ' and is connected and fixed device 3 ', and the eyepiece object lens are fixed at the moment device 6 ', and object lens are concavees lens, and eyepiece is convex lens or goggles or concavees lens.Device 6 ' can be hook or clip, and it can clip on the spectacle frame, and device 6 ' can also be the spectacle frame (not shown).The eyepiece of present embodiment is removable.The preferable parameter of present embodiment is for example: eyepiece focal length+20 centimetre, diopter+500 degree, objective focal length-33.3 centimetre, 5 centimetres of eyepiece object lens spacings, when eyes are read book apart from 30 centimetres far away on eyepiece by the eyepiece object lens, the imaging of Book of Records object lens eyepiece to apart from 380 centimetres on eyepiece and resemble and book at the homonymy of eyepiece.
The formula 1/U+1/V=1/F that two embodiment lens of this utility model adopt when calculating, U is an object distance, and V is an image distance, and F is a focal length.
When above two embodiment of this utility model use, place the object lens below reading thing, turn on lighting source (embodiment illustrated in fig. 1) or utilize external light source (embodiment illustrated in fig. 2), after putting on the near-sighted glasses that can entangle twenty-twenty vision, twenty-twenty vision (standard logarithmic vision 5.0 or more than) eyes or myopia see the reading thing by the eyepiece object lens, eyes can comparatively clearly be seen the word of reading on the thing clearly, and read thing through the distance of the eyes of object lens eyepiece imaging after image when not wearing glasses when wearing near-sighted glasses (or resemble glasses) distance greater than the direct eyes when wearing near-sighted glasses (or book to glasses) when not wearing glasses of book, at this moment eye lens is adjusted to more flat state (with respect to directly not reading a book by above two embodiment), see like this and read thing eyes indefatigability, to vision care and to treat bathomorphic effect better, easy to use.
More than the eyepiece of two embodiment can on original basis, increase by+25 degree and spend the time to+200, eyes or myopia are put on near-sighted glasses and are seen when reading a book by this utility model embodiment, eyes can be recognized the word on publishing books substantially, also can make eye lens to flat direction adjustment, preferable to the curative effect for the treatment of myopia.
For the dioptric myopia of difference, the eyepiece of above two embodiment of this utility model also can be used on the twenty-twenty vision eyes can see the dioptric lens replacement that the eyepiece diopter of word on the book adds the negative dioptric algebraical sum of near-sighted glasses clearly, and myopia is directly seen the reading thing by the eyepiece and the object lens that replaced; More than the also optional eyes of diopter of eyepiece of two embodiment can see the bigger dioptric lens of algebraic value in the time of maybe recognizing on the book word clearly, eyes are directly seen the reading thing by the eyepiece object lens.When bathomorphic diopter was dark, the diopter of the eyepiece of present embodiment may be 0 degree or negative value, and eyepiece can be goggles or concavees lens.
The eyepiece of this utility model embodiment can also be selected any dioptric lens, and (positive and negative, zero diopter all can,-600 degree are preferable to+1000 degree), the eyes word of seeing clearly on the book by the eyepiece object lens that puts on one's glasses selects the diopter algebraic value of institute's eyes fixing upward eyeball bigger.
This eyesight health therapeutic apparatus can be used for vision care and the treatment myopia, used about 20 minutes at every turn, once a day to secondary, use one to three course of treatment seven days to ten days each course of treatment, between per course of treatment every three to five days.
This eyesight health therapeutic apparatus is better, easy to use to vision care and treatment myopia effect.
