Description
Technical field
The present invention relates to optical devices technologies field, especially a kind of device and methods for detecting eyes adjusting force.
Background technology
The eyes of people are that the organ of precision, working environment difference are huge the most on human body（Such as distance is different, light
According to condition difference etc.）, so needing eyes that can be adjusted according to different working environments, to see external object.
For a normal eyes, extraneous parallel rays passes through the dioptric system for the eyes for being completely in relaxation state
After, focus is formed on the retina, which is known as emmetropia, and the refractive power of eyes is called the static state of eyes under the state
Refractive power.But in daily life, such as in fine work and study, object is in the position closer apart from eyes, object hair
The diverging light gone out can focus on behind retina, need eyes to change its refractive status and the picture of object is presented on retina
On, this human eye is called the adjusting of eyes, under the state by changing the phenomenon that refractive power of eyes is to see near objects clearly
The refractive power of eyes is called the dynamic refraction power of eyes.
The refractive power of eyes changes the change of predominantly crystalline lens diopter, and there are two factors：Lenticular plasticity
With stretching for ciliary muscle.The contraction of ciliary muscle causes lenticular deformation, increases its refractive power, and the two coordinates collocation, realizes eye
The adjusting of eyeball.If moderating force is made to weaken or completely lose since physiological muscular strength is weak, ciliary muscle needs constant tension
Deficiency is adjusted to overcome, often causes eye muscle power nervous and visual fatigue；On the other hand, lenticular plastic due to the growth at age
Property is gradually lost, and the regulating power of eyes can decline, i.e., so-called presbyopia, also referred to as presbyopia.
Eyes are in relaxation state, and by its static refraction ability, on the retina by the light focusing of distant place, this is at a distance
Distance between object side principal point of the object away from eyes is known as the far point distance of eyes, which is known as the adjusting far point of eyes, far point away from
From inverse be static refraction degree.When eyes need to differentiate the details of near objects, regulatory function can be employed, when eyes are employed
Its maximal regulated strength, the closest approach at the moment that can be seen are the adjusting near point of eyes, between the object side principal point of eyes
Distance is the anomalistic distance of eyes, and when eyes employ adjusting, the inverse of anomalistic distance is dynamic refraction degree, adjusts near point and far point
The distance between be known as adjustable range, the range between static refraction and maximum dynamic refraction is known as the amplitude of accommodation, that is,
Adjusting force on ordinary meaning.
Emmetropia is infinite remote as far as 5m from seeing, the variation of adjusting force is 0 ~ 0.2D, has only employed the adjusting of 0.2D, is realized
Infinitely great adjustable range changes.For the far point of myopia in certain distance, adjustable range is comparatively small, needs concavees lens
Make up its refractive defects；And after the far point of farsightedness is located at eyeball, no matter it sees the object of any distance, will employ adjusting,
Thus the probability of caused visual fatigue is larger, and convex lens is needed to correct refractive defects.
Adjusting, set and the myosis of eyes link together while occurring when seeing nearly object, referred to as the three of near reflex
Through transport is dynamic.It is about more than simple eye measurement that the collectivity caused by eyes set adjusts the result that eyes can be made to measure the amplitude of accommodation
0.5D.Therefore, simple eye measurement can obtain more accurate eyes amplitude of accommodation data.
The amplitude of accommodation is to react the important indicator of regulatory function, commonly uses push away near method, moves remote method and negative eyeglass method to measure eye
The amplitude of accommodation of eyeball.Push away near method is so that the divergence of light is gradually increased to stimulate the eyes of people to produce by the gradual propulsion of sighting target
Raw to adjust, specific method is that sighting target panel is placed at the moment, slowly mobile from the distant to the near, until sighting target obscures, then slightly
It is moved rearwardly into the position that can be seen clearly, measures distance of the sighting target away from corneal apex, this position is the adjusting near point of eyes, in conjunction with
The refractive error of person under test can obtain the amplitude of accommodation of eyes.It is that sighting target is placed at 5cm at the moment to move remote method, gradually remote
From eyes to find the near point of eyes to be measured.Negative eyeglass rule is to be adjusted by increasing negative eyeglass before eyes to stimulate, to obtain
Obtain the numerical value of the amplitude of accommodation.Above several method is all subjective measurement method, and person under test oneself is needed to judge that nearby sighting target understands
With fuzzy boundary, the technical staff for needing to possess rich experiences instructs and exchanges therewith, the accuracy of testing result rise and fall compared with
Greatly, it is not suitable for adult or the immature child of linguistic function of verbal communication obstacle yet.Measure the method adjusted also
There is dynamic retinoscopy, even if nearby target, two adjustings and set are in active state to two eye gazes of subject,
Therefore two regulating degrees, and the adjusting near point of objective determination eyes can be measured, but competent this method needs are very skilled
Examine shadow technology and experience.In addition there are the computer implemented automatic objective optometry instruments of utilization, its advantage is that quickly, precisely, but one
As price it is more expensive.
The adjustment effect of eyes enables the mankind to see clearly from the moment to the object from far, the daily life for the mankind
It is significant.With the development of industry with the progress of science and technology, in the modern life, the demand of human eye near work is more and more,
On the one hand, human eye depending on it is close when the forfeiture that adjusts（Presbyopia）Change with physiological（The eyes spasm of accommodation, paralysis, fatigue, function are not
Congruence）Eyes can be caused to regard close difficult, influence work and study；On the other hand, heavy near work task makes eyes
Over-burden, and the coordination of the near reflex of eyes and balance are difficult to maintain, and leads to the regulating power reduction or abnormal of eyes, influences day
Often life.Especially refectory teenager, since heavy learning tasks force the adjusting of its eye to be chronically at tense situation,
Muscle and then become spasticity, cause pseudo-myopia, show as facing and decline with the distant vision of slight long sight, near vision is still just
Often.The pseudo-myopia caused by the spasm of accommodation is the multiple situation that students' eyesight reduces.
The measurement of eyes regulating power is for preventing student's visual impairment and finding that eyes regulating power physiological is different early
Often and presbyopia effect is huge.Traditional eyes regulating power detects that ophthalmologic hospital or outpatient service are diagnosed, and uses large size
Expensive instrument and complicated means carry out refractive assessment, and technical staff is needed to carry out language friendship with detected person in detection process
Mutually, human cost is very high, and be difficult suitable for the age is relatively low or personnel with dysaudia, meanwhile, the detection means is not
Conducive to the frequent monitoring and evaluation of regulating power.
