Description
Technical field
The utility model relates to the instruments more particularly to a kind of Plane Rotation of a kind of vision accommodation following test and training
Formula overturns mirror.
Background technique
As the frequency of use of video terminal increases, myopia is more and more.Key of many youngsters and childrens in development
Because near using eyes time is too long, there is asthenopia, regulatory function is abnormal, to cause myopia in phase.Medically mainly from tune
Ocular accommodation situation is evaluated in terms of section amplitude and adjusting sensitivity two, wherein overturning mirror can be used by adjusting the inspection of sensitivity.
Existing overturning mirror connects what four eyeglasses formed by an axis, and axis side is two telescope directs, and the other side is two negative
Mirror drives positive and negative lens set to overturn when use by middle shaft rotation, position exchange is realized, so that fixating eye be made to reach adjustment state
(positive regulator) replaces (negative regulator) with relaxation alternately, each positive regulator and negative regulator are a regulating cycle.It is adjusted checking
When sensitivity, need to have carried out how many a regulating cycles in the statistical unit time.Overturning mirror is also commonly used for that eye is trained to adjust energy
Power, the hand-held overturning of user quickly recognizes sighting target by telescope direct and negative mirror respectively in training, and each training process needs persistently several points
Clock.
It is inconvenient when 1, hand-held overturning mirror is operated that existing overturning mirror overturning has the disadvantage in that, be easy to cause and turns over
During turning measured does not penetrate eyeglass and sees sighting target, will also result in eye distance eyeglass distance and sighting target apart from eye away from
Inspection can not be standardized from being not fixed, and complete switching process in the operating time have delay, these factors all may cause
Technical inspection error；2, existing overturning the mirror timer and counter that do not cooperate with, in detection in the statistical unit time
Overturning number when be easy to appear human error, it is difficult to the regulating time of accurate recording user causes inspection result inaccurate；And
And existing timing metering is a statistics of regulating cycle in the unit time, can not clearly record positive regulator or negative regulator
Respectively with how many duration.3, when existing overturning mirror training adjusts sensitivity, when hand-held overturning mirror is operated, arm fatiguability,
Cause the distance of eye distance eyeglass uncertain, the optical centre of eyeglass and the pupil center of eyes are misaligned etc., and factors influence to instruct
Practice effect.
Since to continue near using eyes time too long by children, it cannot be effectively obtained and loosen, in addition to regulatory function reaches anti-
Near-sighted purpose is controlled, can also regard and train frequently by mist, that is, use a degree of telescope direct, help simple eye or eyes effective respectively
Loosen.
