The progressive lens fitting inspection tester is simple in structure, simple and convenient in operation, low in measurement errors and easy in popularization.

Description

A kind of progressive lenses is joined suitable somascope

Technical field

The utility model relates to a kind of eyeglass and joins suitable somascope, and particularly a kind of progressive lenses is joined suitable somascope.

Background technology

Presbyopia is that the unavoidable a kind of physiological of elderly population changes.Progressive multi-focus lens provides outstanding solution for the presbyopia patient.The glasses that assemble this eyeglass can allow the wearer recover the vision of nature again, no matter far away in in-plant object can both easily see clearly.Along with the development of aging population trend, China will have increasing population to step into old age.Progressive multi-focus lens also will be more and more universal.But the technology content of progressive multi-focus lens is higher, and is also very high for the technical requirement of glasses service provider, especially joins the suitable link of checking what optometry was carried out later on.According to calculating that discomfort appears in the progressive multi-focus lens wearer more than 70% in the industry at present, all check inaccurate causing because join suitable link.The scrutiny program of the complexity that industry is used now and simple and crude instrument, and the frequent supervisory personnel's (being difficult to accumulate enough inspection experiences) who changes, making joining of progressive multi-focus lens fit and checking becomes the key that hinders this outstanding product promotion.

Joining the suitable core of checking is on the liner of eyeglasses frame, the horizontal line and the perpendicular line that at first need mark cornea reflective spot exactly and be the axle center with this point, the cross (joining the mirror cross) that utilizes horizontal line and perpendicular line to constitute again finds corresponding parameter on the canonical measure clamp that each progressive multi-focus lens producer provides, then according to the parameter machining lens that provides.The main method of joining mirror cross sign at present has:

(1) direct method of measurement: this method is to allow client put on selected mirror holder, the examiner by in the flashing pen irradiation now of examiner's homonymy, finds client's pupil reflective spot in client's one arm place far away, use the oil pen then, directly be drawn on the liner wearing under the specular attitude.Though this method operation steps is simple, owing to be to check wearing under the specular attitude, when haptic lens, client's eyes can be shifted, thus the measuring error of causing, so this method there be limited evidence currently of uses.

(2) labelling method in advance: this method is to measure simple eye interpupillary distance with centrometer earlier, utilize the straight line of measuring on the clamp then, perpendicular line draws on the mirror holder liner, contrast the scale on the clamp again, scale draws on perpendicular line, relief client puts on the spectacle frame of finishing scale, with the flashing pen irradiation, reads corresponding scale value.Though it is comparatively accurate that this method is measured, complex steps, and because the liner material smooth surface is drawn the step practical operation of straight line and got up to have any problem on liner, it is horizontal vertically flat to be difficult to assurance, thereby may cause measuring error.This method is used more general at present.

(3) pupil high measurement method: this method is to measure simple eye interpupillary distance with centrometer earlier, utilizes the straight line of measuring on the clamp then, and perpendicular line draws on the mirror holder liner; Choosing the pupil high measurement chi that similar intermediate plate is installed on the mirror holder; Knob on the high chi of rotation pupil, adjustment has the height of the chi plate eyeglass of horizontal scale, and chi plate upper limb is alignd with the cornea reflective spot; Take off the mirror holder that accompanies dip stick, utilize the high chi upper limb of pupil, horizontal linear draws.Though this method measuring process is simple, but the high data of pupil directly read, but because the distance between pupil high measurement chi and the liner is bigger, and weight is big, and glasses can be sagging during measurement, therefore easily causes measuring error.This method application surface is narrow.

Summary of the invention

The purpose of this utility model is to provide a kind of progressive lenses easy and simple to handle, that measuring error is little, simple in structure to join suitable somascope.

For achieving the above object, the solution that the utility model adopts is: this eyeglass is joined suitable somascope and is comprised that crossbeam and symmetry are positioned at two slidies under the crossbeam, centre mark at crossbeam has the symmetric reference point, be distributed with by several horizontal lines that equates at interval and the crossing coordinate grid that forms of perpendicular line in the central area of slide, the length of side that constitutes each lattice of coordinate grid is 0.5-2mm, and left-right symmetric is put with respect to symmetric reference in the coordinate grid zone on two slidies.

The inboard in above-mentioned coordinate grid zone is 20-40mm apart from the horizontal range of symmetric reference point, and upside is apart from slide upper limb 15-45mm.

The horizontal line and the perpendicular line of above-mentioned formation coordinate grid regional center point are through to whole slide.

Use of the present utility model is: (1) is joined suitable somascope with progressive lenses and is connected with frame, guarantees that the symmetric reference point at crossbeam center and the axis of symmetry of mirror holder are consistent, and allows the person under inspection put on then to have connected progressive lenses join the mirror holder of fitting somascope; (2) examiner observes and record person under inspection's pupil reflective spot and the relation between the coordinate sash; (3) take off and connected the mirror holder that progressive lenses is joined suitable somascope,,, mark pupil reflective spot position with the oil pen according to the coordinate position of the pupil reflective spot correspondence that is write down in mirror holder liner rear surface; (4), on the progressive lenses measurement clamp that eyeglass production firm provides, read pupil height, interpupillary distance numerical value according to oil pen's mark.

The utlity model has following effect:

(1) measuring method is simple, has reduced the checked operation error;

(2) coordinate grid and mirror holder are farthest fitted, and have reduced the observation measuring error;

(3) easy and simple to handle, need not reference mark on the liner;

(4) simple in structure, cost is low, easily popularizes;

(5) in light weight, reduced the measuring error that causes because of mirror holder is sagging.
