Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with attached drawing to the present invention
Technical solution be clearly and completely described, it is clear that described embodiments are some of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Currently, during optometry, when accurate axis of astigmatism, mainly uses astigmatism disk sighting target.Traditional astigmatism disk is
Circular, principle is seen to user, and in such a way that optometrist inquires, astigmatism, which is spiraled, to be gone to one user is allowed to see
Then position calculates axle position by formula.But in actual operation, the stepping of astigmatism dish axle position is 15 degree, really for axle position
It is fixed not very accurate.In addition, optist generally requires answer (which item according to patient when determining axle position using astigmatism disk
Line is clearer) come the axle position degree that converts, it spends the time longer and inevitably will appear mistake during conversion, cause with mirror
Inaccuracy.
Based on this, T word astigmatism sighting target provided in an embodiment of the present invention and method is determined based on the axle position of T word astigmatism sighting target,
Efficiency and accuracy that axle position determines can be improved.
To be carried out first to T word astigmatism sighting target disclosed in the embodiment of the present invention detailed convenient for understanding the present embodiment
It is thin to introduce.
Embodiment one:
Fig. 1-2 is the schematic diagram for the T word astigmatism sighting target that the embodiment of the present invention one provides.
Referring to Fig.1-2, T word astigmatism sighting target includes the T word sighting target being distributed on sighting target panel, stepping selection area, axle position degree
Number viewing area and select button.
T word sighting target includes orthogonal and separation the first sighting target and the second sighting target.Wherein, as shown in Figure 1, the first sighting target
Straight line including three different colours；Second sighting target includes the straight line of three different colours.Alternatively, as shown in Fig. 2, the first sighting target
Lines including multiple E words composition；Second sighting target includes the lines of multiple E word compositions.
Stepping selection area and axle position degree viewing area can be respectively arranged at the upper left side and lower right of T word sighting target.Stepping choosing
Selecting area includes 1 °, 5 ° or 15 °；The region that 40 ° of display in 55 ° and Fig. 2 is shown in Fig. 1 is axle position degree viewing area.
Select button includes increasing button and reduction button.
Further, referring to Fig. 3, the realization principle of T word astigmatism sighting target is as follows:
Parallel rays enter astigmatism patient it is intraocular after, since refractive power differs eyeball on different meridians, cannot assemble
In a bit (focus), clearly image cannot be also formed.According to history formula light cone figure it is found that mutually perpendicular lines be imaged on it is scattered
Distance on light eyes retina be it is different, one by it is previous rearward, which item seems this two lines by human eye actually
Apparent to depend on them at a distance from retina, that informant eye close from retina will feel apparent.
Embodiment two:
Fig. 3 is that the axle position provided by Embodiment 2 of the present invention based on T word astigmatism sighting target determines method flow diagram.
Provided T word astigmatism sighting target and its realization principle based on the above embodiment, present embodiments provide a kind of axle position
Determine method.Referring to Fig. 3, determine that method mainly includes following content based on the axle position of T word astigmatism sighting target:
Step S110 is configured axle position degree viewing area, obtains axle position degree initial value；
Step S120 selects stepping selection area, obtains stepping degree appropriate；
Step S130 is based on axle position degree initial value and stepping degree, operates to select button, revolves T word sighting target
Turn；
Specifically, the axle position degree initial value of setting is 0 °；According to patient profiles or optometry demand, stepping appropriate is set
Degree is 1 °, 5 ° or 15 °.
Select button includes increasing button and reducing button, is based on axle position degree initial value and stepping degree, presses to reduction
Button is operated, and T word sighting target is rotated clockwise.And be based on axle position degree initial value and stepping degree, to increase button into
Row operation, rotates T word sighting target counterclockwise.
It by taking stepping degree is 5 ° as an example, clicks and reduces button, axle position rotates clockwise 5 °, and the display of axle position degree increases by 5 °；
It clicks and increases button, axle position rotates 5 ° counterclockwise, and the display of axle position degree reduces 5 °.
Step S140 acquires axle position degree variate-value and the svelteness degree letter of user during the rotation of T word sighting target
Breath；
Step S150 calculates axle position degree value according to axle position degree variate-value and svelteness degree information.
Specifically, patient feedback's horizontal direction and which direction of vertical direction passed through during the rotation of T word sighting target
Svelteness selects stepping and clicks to increase button or reduce button to rotate T word astigmatism sighting target；During rotation, when
When patient feedback's horizontal direction is consistent with the svelteness of vertical direction, the axle position degree variate-value that acquisition lower right is shown, then
Axle position degree value is calculated according to axle position degree variate-value.
Wherein, when reducing button by clicking, when rotating clockwise T word astigmatism sighting target, if axle position degree variate-value
No more than 180 °, then axle position degree variate-value as final determining axle position degree value.If axle position degree variate-value is greater than
180 °, then axle position degree value is calculated according to formula (1):
Wherein, c be axle position degree value, a be axle position degree variate-value, b=180 °.Such as it rotates to axle position degree variate-value
When being 185 °, calculating formula isAxle position degree is shown as 5 °.
When increasing button by clicking, when rotating T word astigmatism sighting target counterclockwise, if axle position degree variate-value is not small
In -180 °, then axle position degree variate-value obtains the axle position degree value that absolute value as finally determines.If axle position degree variate-value is small
In -180 °, then axle position degree value is calculated according to formula (2):
Wherein, c be axle position degree value, a be axle position degree variate-value, b=180 °.Such as it rotates to axle position degree variate-value
When being 185 °, calculating formula isAxle position degree is shown as 175 °.
The embodiment of the present invention bring it is following the utility model has the advantages that
T word astigmatism sighting target provided by the invention and method is determined based on the axle position of T word astigmatism sighting target, comprising: to axle position degree
Number viewing area is configured, and obtains axle position degree initial value；Stepping selection area is selected, stepping degree appropriate is obtained；
Based on axle position degree initial value and stepping degree, select button is operated, rotates T word sighting target；In the rotation of T word sighting target
In the process, the svelteness degree information of axle position degree variate-value and user is acquired；According to axle position degree variate-value and svelteness
It spends information and calculates axle position degree value.The efficiency and accuracy that axle position determines can be improved in the present invention.
