Abstract
The utility model discloses a multifunctional refraction checking lamp box, which comprises a box body and a light source mounted in the box body, wherein the front side plate of the box body adopts a light guide plate; a sighting target region with the letter E is arranged on the light guide plate; at least one region of an astigmatism table region, a dot sighting target region, a polarized sighting target region, a red-green sighting target region and a single row sighting target region is arranged on the light guide plate; and a sighting target layer formed by spraying or attaching corresponding sighting target in the astigmatism table region, dot sighting target region, polarized sighting target region, red-green sighting target region and the single row sighting target region. The multifunctional refraction checking lamp box not only has the function of comprehensively detecting various refraction errors in callans, such as myopia, hyperopia, astigmatism, heterotropia, binoculus apparent equilibrium, fusion and stereoscopic vision, and has the advantages that the structure is simple, the visual examination can be finished accurately and quickly, and the refraction checking lamp box is suitable for being used in hospitals and eyeglasses stores.
Description
Technical field
This utility model relates to a kind of diagnostic tool of the people's of detection refraction of eye degree, relates in particular to a kind of multi-functional examination of refraction lamp box.
Background technology
At present, the visual acuity chart that each hospital and optician's shop use is " E " word visual acuity chart, and this visual acuity chart can only be checked the myopia of eyes and the degree of hypermetropia, and other some dioptric problems can not well be checked, because not comprehensively, give a test of one's eyesight exactly, therefore the glasses of preparation may make a big impact to patient's vision.
Summary of the invention
The purpose of this utility model provides a kind of multi-functional examination of refraction lamp box, solving existing visual acuity chart function singleness, and can not be comprehensively, the problem that gives a test of one's eyesight exactly.
For reaching above-mentioned purpose, the multi-functional examination of refraction lamp box of this utility model, comprise casing and be installed on the intravital light source of case, the front side board of casing is a LGP, " E " word sighting target district is set on the LGP, at least one zone in astigmatic list area, speckle sighting target district, polarization sighting target district, red green sighting target district and the single file sighting target district also is set on the LGP, sprays or attach corresponding sighting target in described astigmatic list area, speckle sighting target district, polarization sighting target district, red green sighting target district and the single file sighting target district and form the sighting target floor.
This multi-functional examination of refraction lamp box not only can comprehensive detection as myopia, hypermetropia, astigmatism, stravismus, eyes look balance, melt picture, various ametropia and eyes function such as stereoscopic vision, and it is simple in structure, can finish vision accurately and quickly and detect, be very suitable for hospital and optician's shop and use.
Further can spray the background color layer on LGP, the sighting target layer is positioned at this above background color layer.So that sighting target seems lively, avoid visual fatigue.
Further the red green sighting target in red green sighting target district can be adopted the earlier green red green again ordering in back, disturb, reach the purpose of the more accurate measurement ball number of degrees to avoid regulating.
The stripe coating that further available length is different constitutes astigmatic chart, looks back examinee's identification so that more help mist.
Description of drawings
The structural representation of Fig. 1 this utility model exemplary embodiments.
The specific embodiment
This multi-functional examination of refraction lamp box is with " E " word sighting target, astigmatic chart, rhombus speckle sighting target, red green sighting target and polarization sighting target are integrated on the multi-functional examination of refraction lamp box, and reasonably laterally arrange, integral body is divided into two parts, left-half is " E " word sighting target and single file sighting target, right half part is an astigmatic chart, rhombus speckle sighting target, red green sighting target and polarization sighting target, astigmatic chart, rhombus speckle sighting target up, red green sighting target and polarization sighting target below, whole rationally distributed, can comprehensive detection such as myopia, hypermetropia, astigmatism, stravismus, eyes are looked balance, melt picture, various ametropia such as stereoscopic vision and eyes function have accurately, practical, simply, characteristics such as quick.Further describe below in conjunction with accompanying drawing.
As shown in Figure 1, this multi-functional examination of refraction lamp box comprises casing 100 and the light source that is installed in the casing 100, the front side board of casing 100 is a LGP 10, " E " word sighting target district 1 is set on the LGP 10, astigmatic list area 2, speckle sighting target district 3, polarization sighting target district 4, red green sighting target district 5 and single file sighting target 6 districts also are set on the LGP 10, spray or attach corresponding sighting target in described astigmatic list area 2, speckle sighting target district 3, polarization sighting target district 4, red green sighting target district 5 and single file sighting target 6 districts and form the sighting target floor.
Be coated with the background color layer on LGP 10, the sighting target layer is positioned at this above background color layer.The background color layer is yellow, and sign adopts green, and background color and sign are soft coloured light like this, change traditional sighting target color dullness, uninteresting, make sighting target seem lively, can effectively avoid visual fatigue.
The red green sighting target in red green sighting target district 5 comprises the sighting target of two green backgrounds and the sighting target of a red background, and the sighting target of red background is between the sighting target of two green backgrounds.Promptly adopt the earlier green red green again ordering in back, can avoid regulating and disturb, thus can the more accurate measurement ball number of degrees.
The astigmatic chart of astigmatism list area 2 is made up of the wide stripe coating of some 3mm, and the stripe coating of level and vertical direction is longer than the stripe coating of other direction, looks back examinee's identification thereby more help mist.
The polarization sighting target is more clear, easier to be distinguished in order to make, and the left lines of the polarization sighting target in above-mentioned polarization sighting target district 4 and following lines are made as green, and right lines and last lines are made as redness.
Speckle sighting target in the speckle sighting target district 3 adopts rhombus speckle sighting target, and promptly middle is that figure is formed with point-like in equilateral rhombus, edge, can very clearly distinguish sighting target shape and svelteness degree.
Light source in the casing 100 is an annular lamp tube, and this light source is provided with brightness regulator, and the user can control the brightness of multi-functional examination of refraction lamp box by manual or remote control mode, and then the brightness of control sighting target.The illumination of this lamp box is 400lx, and brightness is 200cd/m
2About.
Sighting target in above-mentioned each sighting target district can adopt the mode of spraying or printing to be fixed on the LGP 10.Also sighting target can be printed on the plastic sheeting, then they be attached on the LGP 10 in the corresponding sighting target district.
This multi-functional examination of refraction lamp box can be used to comprehensive detection as myopia, hypermetropia, astigmatism, stravismus, eyes look balance, melt picture, various ametropia and eyes function such as stereoscopic vision, and it is simple in structure, can finish vision accurately and quickly detects, and is very suitable for hospital and optician's shop and uses.
