Abstract
The utility model discloses a headgear type dominant eye measuring device, comprising a headgear (1), a connecting rod (2) and a main eye plate (4), wherein one end of the connecting rod (2) is fixedly arranged in the middle of the front side of the edge of the headgear (1), and the other end of the connecting rod (2) passes through a slide hole (7) at the vertical central line of the upper part of the main eye plate (4) to be connected with the main eye plate (4) in a sliding manner; and the main eye plate (4) is provided with a detection hole (8) which is located below the slide hole (7). The connecting rod which is connected with the main eye plate in a sliding manner and is marked with scales is arranged on the front side of the headgear, so that a person to be detected can independently determine the specific position of a dominant eye and can carry out dominant eye measurements in different distances under the conditions of determining a detection distance and a detection direction, the measurement error is avoided, and measuring procedures and a measuring tool are standardized. The headgear type dominant eye measuring device has the characteristics of simple structure, convenience for operation, small size, light weight, stable gravity center, suitableness for wearing and accurate measurement, and is applicable to a wide range of head types and is suitable for being popularized and applied.
Description
Technical field
This utility model relates to eye and looks the light instrument field, relates in particular to the instrument field that people's binocular vision function is measured, specifically a kind of pullover type dominant eye determinator that is used for confirming when mirror is joined in clinical ophthalmology inspection and optometry the other parameter of dominant eye eye.
Background technology
Dominant eye is claimed leading eye, sharp eye and dominant eye again, and being meant two look has that eye of dominant right to be dominant eye in the function.Dominant eye is divided into right dominant eye, left dominant eye, replaces sexual clorminance eye, middle dominant eye etc.So-called alternately sexual clorminance eye is the main alternately exchange of eye of looking, and right eye is a dominant eye sometimes, and left eye is a dominant eye sometimes; Dominant eye is no dominant eye in the what is called, often is two and watches attentively simultaneously.Yet universal law is: right eye is that dominant eye person is in the majority, and left eye takes second place, and alternately the people of sexual clorminance eye and middle dominant eye seldom.The measurement of dominant eye is extremely important clinically; Especially ametropia carries out mirror wildcarding correcting, and testing of presbyopia mono-vision (Monovision) join, tiltedly amblyopia is joined visual exercise behind the mirror, hidden in the training process, or need carry out strabotomy and need carry out the refractive surgery treatment and all should detect dominant eye.The method that detects dominant eye is a lot, like card hole method, thumb method, ODM, preferentially watch method and Worth4 point method attentively.Card hole method is the most frequently used dominant eye inspection method, in the routine work at present, mainly carries out confirming of dominant eye with card hole method, in case of necessity, can combine two kinds even three kinds of dominant eye inspection methods to examine.
Have much though measure the method for dominant eye, the measurement of these methods or need other people's assistance, the examinee can't judge check result separately.Or the easy deflection in measuring position, influence result's judgement.A lot of clinically examinees can't distinguish closed eyes voluntarily, so during the method for execute card hole, need the examiner assist operation to obtain definite result.And daily use card hole method, under a lot of situation, the examinee can't correctly confirm the position and placement distance of dominant eye measuring apparatus, so possibly influence the result, influences the enforcement of standard optometry flow process and the accurately acquisition of prescription.
Summary of the invention
The purpose of this utility model is the defective to prior art, provide a kind of easy to operate, measure pullover type dominant eye determinator accurately.
The purpose of this utility model solves through following technical scheme:
A kind of pullover type dominant eye determinator; Comprise headgear, connecting rod and dominant eye plate; One end of said connecting rod is fixedly installed on the middle part, front side on headgear cover edge; The slide opening that the other end of connecting rod passes the vertical centerline in dominant eye plate top links to each other with the slip of dominant eye plate, and the dominant eye plate is provided with the detection hole that is positioned at the slide opening below.
The diameter in said detection hole is 1-2cm.
Described detection hole is positioned at the center position of dominant eye plate.
The surface of said connecting rod is provided with scale.
Said graduated length is not more than 50cm.
Described headgear is provided with horizontal position adjustment knob and upright position adjustment knob, and described horizontal position adjustment knob is positioned at the position, both sides on headgear cover edge, and upright position adjustment knob is positioned at the top of headgear.
Described dominant eye plate adopts plastic plate to process.
This utility model is compared prior art has following advantage:
This utility model links to each other with the dominant eye plate through indicating graduated connecting rod in the setting of the front side of headgear; And the scale on connecting rod surface makes eye conform to the nominal scale with the main actual range of looking plate; Avoid distance difference to influence measurement result, make the examinee can confirm the concrete orientation of dominant eye separately; And can pass through the slip of dominant eye plate on connecting rod, confirm to detect distance, detection side to situation under carry out different distance dominant eye measure, the measurement error of avoiding the hands skew to cause is carried out standardization to process of measurement and measuring appliance simultaneously.
This utility model is provided with horizontal position adjustment knob and upright position adjustment knob respectively through side and the top at headgear, makes this headgear be applicable to different head dummys; And dominant eye plate that light material is processed and connecting rod make and are fit to be worn on head by in light weight, the steadily of centre of gravity of package unit.
This utility model is simple in structure, easy to operate, have volume little, measure characteristic of accurate, suitable promoting the use of.
