Description
Technical field
The invention belongs to eyesight detection technique fields, specifically, being related to a kind of isomery visual chart examined for eyesight
And the eyesight method of inspection.
Background technique
Eyesight is one of common somatic eigenstate index, and China generallys use " 11533 standard logarithmic visual acuity chart of GB "
The problem of examining eyesight, but in eyesight checkout procedure, being primarily present has:
(1) inspection result of eyesight relies on subjective cooperation and states with master, and there are false situations.Pass through conventional visual chart
It tests, 5 meters of standard test distances can correctly recognize that the minimum sighting target of more than half is eyesight, and default preferably master states eyesight
To be examined people's real visual acuity.It is stated due to highly relying on subjective cooperation and master in checkout procedure, and the view of the various eyesights of visual chart
Mark direction and sequence be it is fixed, main when stating untrue, inspection result cannot reflect real visual acuity.For example, being risen to reach
The visual demands such as learn, join the army, working, when inspection learns the sighting target direction of the higher eyesight of -2 row of 1 row by heart to pretend high eyesight.For another example,
In criminal judgement, victim pretends to claim to recognize that the sighting target of low visual acuity to pretend low visual acuity, causes wrong identification, and allows aggrieved
People is more compensated or inflictor punishes and aggravates.Inventor has found the knot by changing visual chart in the course of the research
Structure examines distance and transformation sighting target size and direction, and examined people can be effectively prevent to learn that sighting target puts in order and pretends height by heart
Eyesight.Since consciousness system can pretend low visual acuity by the estimation to sighting target size and sighting target distance, thus it is low to pretending
Eyesight person is difficult to effectively judge.Camouflage low visual acuity is still the Important Unsolved Problems that eyesight is examined, even if discovery eyesight reduction can not
It explains, suspect camouflage, clearly judgement and conclusion can not be also made due to a lack of basis, is allowed using dummy results.
(2) eyesight identification is inconsistent, and low visual acuity examines error larger." 11533 standard logarithmic visual acuity chart of GB " each row
The sighting target of eyesight, which is 2-8, to be differed, and assert eyesight according to " recognizing that correct sighting target number is more than sighting target sum half ", practical to assert
The sighting target number and disunity of Shi Caiyong.The especially inspection of low visual acuity, low visual acuity are one of visual function important states, usually
It is related to the social concerns such as social security, damage to person settlement of insurance claim, however, low visual acuity in " 11533 standard logarithmic visual acuity chart of GB "
Sighting target is 2-4, and low visual acuity examines error larger.
Summary of the invention
The present invention is difficult to judge for eyesight inspection result authenticity present in existing eyesight checkout procedure, low visual acuity inspection
The above-mentioned deficiencies such as error is big are tested, a kind of isomery visual chart, eyesight verifying attachment and the method for inspection are provided.By by different size
Sighting target and perspective view constitute size parablepsia figure be used as visual chart, change eyesight table structure, examined people is repeatedly examined
The real visual acuity to obtain examined people is tested, can effectively find camouflage eyesight, especially camouflage low visual acuity.
Eyesight is sensing capability of the people to extraneous article size, is both influenced by external stimulus to the sense organ, also by interior
The influence of portion's cognitive process.The process of these cognitions is influenced by factors such as previous experience, memories.Testee is using
When conventional visual chart carries out eyesight detection, the main this special sensing capability according to article size pretends eyesight.Parablepsia is
When people observes object, false judgment and perception that based on empiricism or improperly object of reference is formed.The application will be different big
The parablepsia figure that small sighting target and perspective view is constituted is as visual chart, by causing the illusion of space or depth perception to interfere to article size
Judgement, but the discrimination of real visual acuity is not influenced, and then distinguishes camouflage eyesight.
In order to achieve the above object, the present invention provides a kind of isomery visual chart, the isomery visual chart is to be joined by isomery
According to the size parablepsia figure of area's at least two kinds of sighting targets composition different with size, isomery reference zone be can result in ruler not of the same race
The erroneous judgement of very little sighting target size visually thinks certain smaller sighting target not less than another larger sighting target.
Preferably, the isomery reference zone is that can generate the perspective view that space or depth perception influences to sighting target of different sizes, by M
A larger sighting target puts in the perspective visually closer proximity, places N number of in the perspective visually more compared with microspecies sighting target
The positive integer that remote position, M and N are >=1, by causing the illusion to space or depth perception, and then leads to the view to not same dimension
Mark the erroneous judgement of size.
Preferably, described that the perspective view that space or depth perception influences is generated in the constant parablepsia figure of size on sighting target of different sizes
Background parts, e.g., perspective view are the grid pattern that the first lines, the second lines and third lines are constituted, several the first lines
It is concentrated along depth direction to a bit, several the second lines being parallel to each other intersect with the first lines in the horizontal direction, several
The third lines that item is parallel to each other intersect with the first lines in vertical direction.
Preferably, the isomery reference zone further includes that can make relatively to neglect to be marked on visually more greatly, and biggish sighting target is regarding
Smaller Illusion Figure in feel, the Illusion Figure include but is not limited to alphabetical figure, digital figure, geometry figure, cone
The picture of above-mentioned parablepsia function may be implemented in body etc..Preferably, alphabetical figure is sighting target figure identical with sighting target structure.
Preferably, color blocks are additionally provided between the isomery reference zone different two groups sighting target, are separated by color blocks and is connected
Two groups of sighting targets, visually form subregion.
When the quantity of the sighting target is two kinds, the 1st kind of sighting target includes the small sighting target of several sizes, the 2nd kind of sighting target packet
Include the big sighting target of several sizes, and the size of the 1st kind of sighting target is 0.64-0.99 times of the 2nd kind of sighting target size, every kind of sighting target with
The lines or Illusion Figure that isomery reference zone is constituted around it are left white distance as more than half of this kind of sighting target width, adjacent
Between two kinds of sighting targets being left white distance be larger sighting target width more than half, each sighting target all containing four direction at least
5 sighting targets, and the direction of two neighboring sighting target is different.Specifically, isomery reference zone is the 1st kind of sighting target identical with sighting target structure
Figure and the 2nd kind of sighting target figure, the 1st kind of sighting target figure and the 2nd kind of sighting target figure are respectively placed in the 1st kind of sighting target and the 2nd kind of sighting target
Around, the 1st kind of sighting target dimension of picture size is not more than 0.5 times of the 1st kind of sighting target, and the size of the 2nd kind of sighting target figure is not small
In 1.5 times of the 2nd kind of sighting target, by generating ebbinghaus illusion, so that the 1st kind of sighting target is visually seemed bigger, make the 2nd kind of view
Mark visually seems smaller, and then the normal judgement to sighting target size is influenced.The sighting target figure is specially E word sighting target figure
With C word sighting target figure, the two principle is identical.The cone body is between 2 kinds of sighting targets, and the point of cone body is in the attached of the 1st kind of sighting target
Closely, the bottom surface of cone body is near the 2nd kind of sighting target.
Preferably, the size of the 1st kind of sighting target is 0.79-0.81 times of the 2nd kind of sighting target size.
In order to achieve the above object, the present invention provides a kind of eyesight methods of inspection, comprising the following steps:
Eyesight inspection is carried out by isomery visual chart, isomery visual chart to be measured is made to be examined people relatively from far near or by close
To remote mobile, change the inspection distance being examined between people and isomery visual chart to be measured, until any 1 group of sighting target by examined people just
Really more than half is not achieved in identification, records the number that two kinds of sighting targets are correctly recognized in isomery visual chart respectively, calculates and record inspection
The eyesight tested;
Standard vision inspection is carried out by standard logarithmic visual acuity chart, in testee apart from standard logarithmic visual acuity chart to be measured
It checks and is detected at distance, the eyesight of records tests,
In the process for same examined people, number >=1 time tested using isomery visual chart, according to the different of inspection
Weak-eyed between structure visual chart, between isomery visual chart and standard logarithmic visual acuity chart judges to be examined whether the eyesight of people is true
Real eyesight.The specific determination method of eyesight are as follows:
Define 1 behavior, 1 standard vision row as defined in standard logarithmic visual acuity chart;
If above-mentioned weak-eyed is in 1 standard vision row, it may be assumed that weak-eyed≤1 standard vision row, then standard logarithmic visual acuity chart
The eyesight of inspection is real visual acuity;
If above-mentioned weak-eyed, there is one to reach 2 standard vision rows or more, it may be assumed that weak-eyed >=2 standard vision rows, or because of quilt
Identifier, which mismatches, cannot complete to examine, then mismatches for inspection, the eyesight that standard logarithmic visual acuity chart is examined is false eyesight;
If 2 standard vision rows are still not achieved in above-mentioned weak-eyed, but isomery visual chart is examined and occurs correctly recognizing the 1st kind of view
Mark and cannot correctly recognizing exist between the 2nd kind of sighting target or each secondary eyesight can not reasonable dismissal contradiction, then may for it is subjective not
Cooperation, the eyesight that standard logarithmic visual acuity chart is examined may be false eyesight.
Further, the eyesight method of inspection further includes carrying out eyesight inspection by single vision table, is made to single vision table
It is moved from far near relative to examined people, changes the inspection distance being examined between people and single vision table to be measured, until being examined people
It can correctly recognize the maximum distance of more than half sighting target, calculate the eyesight of simultaneously records tests,
The single vision table is the plan view that forms of at least five sighting target by same size, in the visual chart, sighting target
Direction has 4 kinds, being left white distance between 2 sighting targets of arbitrary neighborhood as more than half of sighting target width, and vertical direction is taken up an official post
2 sighting target directions for anticipating adjacent are different, and 2 sighting target directions of arbitrary neighborhood are different in horizontal direction;
In the process for same examined people, number >=1 time tested using isomery visual chart and single vision table, root
According between the isomery visual chart of inspection, between single vision table, between isomery visual chart and single vision table, isomery visual chart and standard
Weak-eyed between logarithmic visual acuity chart, between single vision table and standard logarithmic visual acuity chart judges to be examined whether the eyesight of people is true
Real eyesight, specific determination method are as follows:
Define 1 behavior, 1 standard vision row as defined in standard logarithmic visual acuity chart;
If above-mentioned weak-eyed is in 1 standard vision row, it may be assumed that weak-eyed≤1 standard vision row, then standard logarithmic visual acuity chart
The eyesight of inspection is real visual acuity;
If there is one to reach 2 standard vision rows or more in above-mentioned weak-eyed, it may be assumed that weak-eyed >=2 standard vision rows, or because of quilt
Identifier, which mismatches, cannot complete to examine, then mismatches for inspection, the eyesight that standard logarithmic visual acuity chart is examined is false eyesight;
If 2 standard vision rows are still not achieved in above-mentioned weak-eyed, but isomery visual chart is examined and occurs correctly recognizing the 1st kind of view
Mark and cannot correctly recognizing exist between the 2nd kind of sighting target or each secondary eyesight can not reasonable dismissal contradiction, then may for it is subjective not
Cooperation, the eyesight that standard logarithmic visual acuity chart is examined may be false eyesight.
Compared with prior art, the advantages and positive effects of the present invention are:
(1) isomery visual chart of the present invention is made of at least two kinds of different size of sighting targets, when sighting target is 2 kinds, neglects target
Size is 0.64-0.99 times of big sighting target size.When the inspection distance between isomery visual chart and examined people is examined people
Can correctly recognize neglect target apart from when, examined people correctly can recognize big sighting target simultaneously.If being examined people master states energy correctly
Small sighting target is recognized without can correctly recognize big sighting target, the identification abnormal prompt examined people master states falseness, and early warning subjectivity is unworthy of
It closes, camouflage eyesight.
(2) isomery visual chart of the present invention is big to be made of the isomery reference zone at least two kinds of sighting targets different with size
Mistake view, comprising the sighting target that at least two kinds of sizes are different in isomery visual chart, when between isomery visual chart and examined people
Inspection distance can recognize the maximum distance of big sighting target to be examined people, the small sighting target of size exceeded the eyesight of examined people and
It cannot correctly recognize, at least two kinds of size sighting target designs improve the accuracy of inspection.
(3) isomery visual chart of the present invention, the figure that at least two kinds of different size of sighting targets are made of by being equipped with multiple groups lines
Isomery reference zone, the vision size that the sighting target for keeping size small is shown not less than the vision size that the big sighting target of size is shown,
When inspection, at least two kinds of different size of sighting targets are easy to be obscured by examined people, can make to be examined the raw big minor error of sighting target of human hair
Judgement prevents to be examined people from pretending, improves and examine accuracy.In addition, isomery visual chart there is also another when examining
Identification is abnormal, i.e., in the same primary inspection of same isomery visual chart, the visual outcome of two inspection distances cannot be solved rationally
It releases.0.8 and 0.888 sighting target can be correctly recognized and 2.68 meters cannot recognize 0.8 and 0.888 sighting target, eyesight 0.40 such as 2.48 meters
With 0.436 and eyesight < 0.429 and < 0.472.0.436 can be seen clearly and 0.429 cannot be seen clearly and be unable to reasonable dismissal, then prompt to lead
It is not good enough to see cooperation.
(4) eyesight verifying attachment of the present invention using isomery visual chart and the two different visual charts of standard logarithmic visual acuity chart into
Row eyesight is examined, and since at least two kinds of sighting targets that isomery visual chart uses are easy to be obscured by examined people, can make to be examined human hair
Raw sighting target size false judgment prevents to be examined people and improves from pretending and examine accuracy, therefore will pass through isomery visual chart and mark
Whether the eyesight that the weak-eyed judgment criteria logarithmic visual acuity chart that quasi- logarithmic visual acuity chart is examined is examined is real visual acuity, can effectively be sent out
Now pretend eyesight and overcomes the high eyesight of camouflage.
(5) eyesight verifying attachment of the present invention is additionally provided with single vision table, single vision table and isomery visual chart and standard logarithmic regards
Power table, which is used in conjunction with, carries out eyesight inspection, and inspection is repeated several times, and inspection result is more acurrate.
(6) eyesight verifying attachment of the present invention is equipped with Mobile support device and sighting target size setting module, is supported by mobile
Device changes the distance between visual chart and examined people, and the size of sighting target is set by sighting target size setting module, examines view
When power, the sighting target size used is examined every time and examines distance difference, and inspection is repeated several times, inspection result is more acurrate.For example,
Certain is examined people's decimal eyesight 0.25, examines it preferably main to state eyesight and have: 4.4 meters of distance 0.3 sighting targets of identification, 5 meters of identifications 0.27
Sighting target, 6.3 meters of 0.2 sighting targets of identification etc..
(7) eyesight verifying attachment of the present invention and the method for inspection, real visual acuity, that is, eyesight minimal visual angle of inspection.Using multiplicity
Change and examine, lacks the eyesight table structure that can be recited, minimum eyesight sighting target can only be recognized by real visual acuity by pretending high eyesight person,
It can not pretend high eyesight.
(8) due to camouflage low visual acuity person by select best eyesight it is below it is a certain compared with low visual acuity as preferably lead state view
Power can actually recognize that sighting target is higher than preferably master and states eyesight, when repeatedly examining, establishing criteria logarithmic visual acuity chart eyesight table structure be needed
The low visual acuity for keeping it to select.Eyesight verifying attachment of the present invention and the method for inspection, because eyesight table structure is different, and the size of sighting target
It is changing with direction, the inspection distance of visual chart is also changing, and camouflage low visual acuity person loses eyesight inspection result and sentences
Disconnected foundation can not remain that the identical lower master of falseness states eyesight in visual chart, sighting target and distance change, occur preferably main
The phenomenon that eyesight is good or bad is stated, examined people's subjectivity is confirmed and mismatches, pretends eyesight.Especially examined using isomery visual chart
When, camouflage low visual acuity person often selects the sighting target appeared larger, and often appearing as " can recognize and neglect mark and cannot recognize big view
The contradiction for being difficult to reasonable dismissal of mark ", the present invention examine the method for eyesight being capable of early warning possible spoofing low visual acuity.
(9) it examines height to rely on due to eyesight and is examined the cooperation of people's subjectivity, if there is not watching or do not recognize view attentively actively
Situations such as mark, can not then be examined and obtain its real visual acuity.If multiple inspection preferably master states, eyesight is dramatically different, and violating eyesight can
Repeated authentication principle can make subjectivity according to this and mismatch judgement.Eyesight verifying attachment of the present invention and the method for inspection utilize above-mentioned master
Sight, which mismatches judgement conclusion and carries out subjectivity, mismatches judgement, meets eyesight and examines rule, and science is reliable, and perfect eyesight, which is examined, to be tied
The type of opinion can effectively prevent camouflage eyesight person to obtain illegal profit, have positive and important realistic meaning.
(10) eyesight verifying attachment of the present invention and the method for inspection are utilized, it, can be more with integrated use when carrying out eyesight inspection
Kind precautionary measures prevent from being examined people's camouflage eyesight, such as: inspection interval closes mesh rest, cuts down the of short duration note to sighting target and distance
Recall;The random visual chart different using sighting target direction, prevention learn that sighting target puts in order by heart.
(11) eyesight verifying attachment of the present invention and the method for inspection are examined use different views every time when carrying out eyesight inspection
Power table, different size of sighting target and by closely to remote or change examine distance or 5 meters of standard test distances from far near, multiplicity
Change and preferably master is repeatedly examined to state eyesight, inspection result relies on true best eyesight, and the subjectivity person of mismatching does not give eyesight and examines knot
By eyesight conclusion is true and reliable.

Power table carries out eyesight inspection, makes to move from far near to single vision table relative to examined people, changes and is examined people and single vision table
Between inspection distance calculate and records tests until the maximum distances of sighting targets more than half can correctly be recognized by being examined people
Eyesight.As long as adjacent step does not use same visual chart to test, the sequence between variety classes visual chart be can be interchanged,
It does not repeat one by one herein.
When carrying out eyesight inspection, the distance that eyesight is examined is 2-7 meter, isomery visual chart from 2 meters to move at 7 meters or by
Moved at 7 meters at 2 meters, single vision table from 7 meters to 2 meters of place's movements.Isomery visual chart by closely to remote or from far near move,
To the better effect that two different sighting targets are obscured, it can make to be examined the raw false judgment of human hair, prevent examined people from pretending,
It improves and examines accuracy.Single vision table moves from far near, and examined people can be effectively prevent to learn that sighting target arrangement carries out in proper order by heart
Camouflage improves and examines accuracy.
When each eyesight is examined, the sighting target in every kind of visual chart manually or automatically changes the direction of sighting target, makes every time
Examine the sighting target direction in each visual chart of eyesight different.By changing the direction of sighting target, prevent examined people from learning sighting target by heart
It puts in order to pretend eyesight, further increases the accuracy for examining eyesight.
When carrying out eyesight inspection, in order to further increase the accuracy of inspection, the sighting target size examined when examining every time
Gap is more than 1 standard vision row, and adjacent eyesight twice examines the visual chart used different.It is examined using different visual charts
It tests and the sighting target size gap examined is more than 1 standard vision row, the size of sighting target is examined by changing, can be improved inspection
Accuracy, effectively discovery camouflage eyesight.
When carrying out eyesight inspection, in order to further increase the accuracy of inspection, the time interval examined every time is at least 5
Minute, in the time interval, it is examined people's sound insulation shading and closes mesh rest.Using time interval allow examined people close mesh rest to
The short-term memory for cutting down to sighting target and examining distance prevents from being examined people to sighting target and examines the influence apart from short-term memory, into
One step improves the accuracy for examining eyesight.
When carrying out eyesight inspection, in order to guarantee to examine the correctness of eyesight, single vision table, isomery visual chart and standard
Logarithmic visual acuity chart is at least examined once, and amount of testing is more, examines the accuracy of eyesight higher, specifically can be according to examined
The number of the actual conditions selection check of people and the number for using various visual charts.
Such as: single vision table, isomery visual chart and standard logarithmic visual acuity chart are examined 1 time, successively according to isomery eyesight
The sequence that table inspection-single vision table inspection-standard logarithmic visual acuity chart is examined carries out eyesight inspection.Various visual charts respectively examine one
Secondary, compared with the existing method of inspection, the accuracy of inspection is high, but is carried out relative to using the method for the present invention using various visual charts
For repeatedly examining, primary mode is examined only with each, the accuracy of inspection is minimum.
Another example is: single vision table and standard logarithmic visual acuity chart are examined 1 time, isomery visual chart is examined 2 times, successively according to different
The sequence that structure visual chart inspection-single vision table inspection-isomery visual chart inspection-standard logarithmic visual acuity chart is examined carries out eyesight inspection
It tests.Examined twice using isomery visual chart, can preferably find the examined people of camouflage eyesight, the accuracy of inspection into
One step improves.
The advantages of in order to be illustrated more clearly that the above-mentioned isomery visual chart of the present invention, eyesight verifying attachment and the method for inspection,
Further explanation is made to the above-mentioned isomery visual chart of the present invention, eyesight verifying attachment and the method for inspection below in conjunction with specific experiment.

It is raw, understand experiment purpose and process, is ready actively to cooperate experiment.Examine distance are as follows: 2 meters -7 meters, decimal eyesight and sighting target and inspection
Test the relationship of distance are as follows:
Eyesight=sighting target eyesight × inspection distance/5
Single vision table is using the single vision table being made of shown in Figure 10 5 sighting targets.Isomery visual chart is used such as Fig. 1-Fig. 9 institute
Show that, by 2 kinds of sighting targets of different sizes, the size of the 1st kind of sighting target is 0.8 times of the 2nd kind of sighting target, each sighting target is by 5 sighting target groups
At isomery visual chart.
The sighting target of each visual chart and the relationship of eyesight are referring to table 1.
Table 1
5 points of eyesights | Visual angle α (') | Designed distance D (m) | Sighting target side length (mm) | Decimal eyesight V |
5-lgα | 10n | 5α | 5×5000αρ | 1/α |
In table 1, ρ is mathematic sign, and 1 ' radian number, value is 2.90888 × 10-4rad。
Two identifiers are chosen successively to test according to following below scheme using above-mentioned eyesight verifying attachment:
S1, the first identifier examine the real visual acuity for being examined people according to standard logarithmic visual acuity chart, record eyesight 1.
S2, be examined people and independently select camouflage eyesight or do not pretend eyesight, when camouflage eyesight, examined people must with it is true
Eyesight lowers or improves 2 row of eyesight or more, repeatable to verify as pretending successfully.First identifier examines according to standard logarithmic visual acuity chart
The real visual acuity or camouflage eyesight of examined people are tested, and records eyesight 2;If selection camouflage eyesight, is examined people's quilt simultaneously
Inform replacement identifier, and in second identifier's inspection period, examined people should keep camouflage eyesight, if finding to be examined people not
Cooperation is camouflage failure.
Camouflage eyesight helps: the standard logarithmic visual acuity chart that uses of experiment of reprinting books in a reduce format, put up and in examined people nearby.
S3, visual chart is changed to isomery visual chart, the second identifier regards examined people by isomery visual chart
Force inspecting, by isomery visual chart from 2 meters to movement at 7 meters, until any a kind of sighting target is correctly recognized by examined people and is not achieved 3,
And correctly recognize that other a kind of sighting target reaches 3 or more, the correct identification number of 2 kinds of sighting targets is recorded respectively, is calculated eyesight and is recorded
Eyesight 3.
S4, visual chart is changed to single vision table, the second identifier carries out eyesight inspection to examined people by single vision table
It tests, by single vision table from nearby being moved at 7 meters to proofer, until the maximum distance of 3 or more sighting targets can be recognized correctly, calculates view
Power simultaneously records eyesight 4.
S5, visual chart is changed to isomery visual chart, the second identifier regards examined people by isomery visual chart
Force inspecting, by isomery visual chart from 2 meters to movement at 7 meters, until any a kind of sighting target is correctly recognized by examined people and is not achieved 3,
And correctly recognize that other a kind of sighting target reaches 3 or more, the correct identification number of 2 kinds of sighting targets is recorded respectively, is calculated eyesight and is recorded
Eyesight 5.
S6, visual chart is changed to standard logarithmic visual acuity chart, the second identifier is by standard logarithmic visual acuity chart to examined
People carries out eyesight inspection, records eyesight 6.
S7, the second identifier independently judge conclusion, specific judgment method to the authenticity of eyesight 6 are as follows: if step S3,
The maximum weak-eyed between 4 eyesight 3, eyesight 4, eyesight 5 and the eyesights 6 for examining eyesight to obtain that S4, S5, S6 are carried out exists
Within 1 standard vision row (i.e.≤1 standard vision row), then eyesight 6 is real visual acuity;If weak-eyed reach 2 standard vision rows with
It upper (i.e. >=2 standard vision row) or cannot complete to examine because mismatching, be mismatched for inspection, 6 falseness of eyesight;If 4 inspections regard
2 standard vision rows (i.e. < 2 standard vision row) is still not achieved in the weak-eyed of eyesight 3, eyesight 4, eyesight 5 and eyesight 6 that power obtains,
But isomery visual chart, which is examined, to be occurred correctly recognizing the 1st kind of sighting target and cannot correctly recognizing the 2nd kind of sighting target, or is regarded in an isomery
During power table is examined, two different to examine that be unable to existing for the visual outcome exist between reasonable dismissal or each secondary eyesight can not
The contradiction of reasonable dismissal, then possible subjectivity is mismatched, and eyesight 6 may be false.Record the judgement conclusion to 6 authenticity of eyesight.
S8, exhort that examined people examines real visual acuity, the first identifier examines according to standard logarithmic visual acuity chart and is examined people
Real visual acuity, record eyesight 7.
According to eyesight 1, eyesight 2 and eyesight 7,6 judgement conclusion of eyesight is verified.Inspection result is shown in Table 2.
2 eyesight of table examines experimental result
Referring to table 2, according to the experimental results, No. 16, No. 43 and No. 74 examined people do not inform real visual acuity, 3 realities
It is invalid to test, effectively experiment 78.
78 experiments, 2 conclusion mistakes, conclusion error rate are 2.56%.5 real visual acuity experimenters, 4 judgements are just
Really, 1 shows as " small sighting target can be recognized without that can recognize big sighting target " and is judged as suspicious in the inspection of isomery visual chart, is detailed in 17
Number.Pretend high eyesight 4, be found, in addition 7 volunteers abandon pretending high eyesight after understanding the method for inspection.Pretend low view
Power 70, correct judgment 68, accuracy 97.1%, 2 false judgments are real visual acuity, are detailed in No. 20 and No. 58.
35.7%, 25 camouflage low visual acuity persons 29 times in the inspection of isomery visual chart, show as " can recognize small sighting target without
The identification of the big minor error of sighting target of the big sighting target of energy identification " is abnormal;Other 24.2%, 17 is pretended low visual acuity person 19 times, primary
During isomery visual chart is examined, two different to examine and is unable to reasonable dismissal, such as No. 32 eyesights 5,5.2 existing for the visual outcome
Rice can correctly recognize 3 or more 0.4 and 0.445 sighting target, and then all cannot correctly recognize 0.4 and 0.445 sighting target at 5.5 meters, depending on
Power shows as 0.416 and 0.463 and < 0.439 and < 0.490.The total identification of the two is 38 abnormal, in camouflage low visual acuity person
Occurrence rate is 38/70,54.3%.
Pretend high eyesight person and does not occur identification exception;1 real visual acuity person, No. 17 because be examined people guess at random sighting target side
To cooperation is not good enough, the phenomenon occurs.
Camouflage low visual acuity person is judged as suspicious conclusion 4, eyesight inspection result have can not reasonable dismissal contradiction.Example
Such as, specifically, within No. 5 examined total 1 standard vision rows of weak-eyed of people, eyesight inspection result contradiction are as follows: eyesight 3 is denied can
Identification 0.198, is not inconsistent with eyesight 5 and eyesight 6.In fact, No. 5 are examined artificial women, 22 one full year of life, senior,
300 degree of spectacles, astigmatism degree is unknown not to be corrected.And 0.25 sighting target slightly mould clear according to No. 5 examined 0.2 sighting targets of people's readme
Paste, 0.3,0.4 and 0.5 is more fuzzy, pretends low visual acuity according to fog-level.Regulation experiment schemes after No. 50, to having " no
The suspicious judgement of the eyesight inspection of energy reasonable dismissal " increases by 1 isomery visual chart or examines with 1 single vision table, therefore after No. 50
Do not occur suspicious conclusion again.
2 misjudgments are all from camouflage low visual acuity, and inspection result performance is " weak-eyed≤1 standard vision row ".Its
In No. 20 examined people, female, 19 years old, sophomore.Right eye astigmatism, degree is unknown not to be corrected, is not worn glasses usually.According to
Whether astigmatism degree is leaned in No. 20 examined people's readmes, it can be determined that be 0.2 sighting target to pretend low visual acuity.No. 58 examined people,
Male, 24 years old, Computer Image Processing professional student working on a postgraduate program, readme can determine whether that sighting target size, method are unknown.
Other No. 67, No. 71 and 77 st volunteers are participation experiment for the second time, and No. 79, No. 80 and 81 st volunteers are this reality
The identifier tested also as people's participation experiment is examined, does not influence result because being familiar with the method for inspection and process.
