Background
Suppression is a visual perception function in which an image seen by one eye is suppressed from being perceived, in order to avoid collision of two different retinal images, and the nerves of this visual information process are altered in the brain rather than the eyes. Inhibition not only results in reduced vision, but also destroys binocular vision, particularly stereoscopic vision. In clinical ophthalmology, amblyopia, strabismus, myopic patients, and people with binocular vision abnormalities all present different degrees and types of inhibition. The Worth four-hole lamp/four-point diagram is the most common inspection inhibition mode, all four-hole lamps and four-point diagrams are composed of four image points and are composed of red, green and white three colors, and binocular vision is completed mainly by red and green lenses. This method only reflects the cases of binocular inhibition roughly, and cannot specifically distinguish whether the site of inhibition is the nasal side or the temporal side, nor can it obtain a quantitative index of the extent of inhibition.

In one embodiment, the nasotemporal suppression position and degree data acquisition system further comprises:
the display control module 31 is configured to control the flicker frequency and/or contrast and/or spatial frequency and/or size of the first pattern displayed by the first display module 10 in each quadrant according to the display control command input by the user.
When the user feedback cannot see the first pattern of one or more quadrants, the flicker frequency of the first pattern can be adjusted through the display control module 31, for example, when the user feedback cannot see the first pattern of one or more quadrants, the output energy of the first pattern of one or more quadrants can be increased by starting to flicker or increasing the flicker frequency through the display control module 31, so that the first pattern which cannot be seen by the user originally becomes easier to see, and when the user can see the first pattern of four quadrants, data acquisition can be continuously performed on the contrast suppression condition of the nasal side and/or the temporal side of the user. According to the flicker frequency of each first pattern when the user feeds back the first patterns of the four quadrants to be seen, the inhibition degree of the nasal side and/or the temporal side of the user can be judged.
When the color shades of the first patterns of the four quadrants seen by the user feedback are different, the contrast of the first patterns can also be adjusted by the display control module 31, for example, when the first patterns of the one or more quadrants seen by the user feedback are lighter, the contrast of the first patterns of the one or more quadrants is improved by the display control module 31 or when the first patterns of the one or more quadrants seen by the user feedback are darker, the contrast of the first patterns of the one or more quadrants is reduced by the display control module 31, so that the color shades of the first patterns of the four quadrants seen by the user are the same. According to the contrast of each first pattern when the color shades of the first patterns of the four quadrants are the same, the degree of contrast inhibition of the nasal side and/or the temporal side of the user can be judged.
And when the data of the nasal-temporal side inhibition position and the degree are acquired, the spatial frequency and/or the size of the first pattern can be adjusted, and the data of the nasal-temporal side inhibition position and the degree are repeated for a plurality of times, so that the acquired data of the nasal-temporal side inhibition position and the degree can more comprehensively and accurately reflect the nasal-temporal side inhibition condition of the user.
In one embodiment, the nasotemporal suppression position and degree data acquisition system further comprises:
the control display module 40 is configured to display controls in four quadrants on the plane respectively, where the controls displayed in each quadrant are respectively configured to receive a display control command input by a user for a first pattern displayed in each quadrant.
The control displayed in each quadrant can be convenient for a user to control the first pattern displayed in each quadrant by clicking the control, so that the operation of data acquisition of the suppression position and the degree of the nasal-temporal side is simpler and more convenient. When the user needs to adjust the flicker frequency and/or contrast and/or spatial frequency and/or size of the first pattern of a certain quadrant, this can be achieved by clicking on the control displayed in that quadrant.
Preferably, the nasotemporal suppression position and degree data acquisition system further comprises:
the data acquisition module 50 may be configured to acquire the flicker frequency and/or contrast of the first pattern according to a confirmation command input by a user, and may also be configured to display the flicker frequency and/or contrast of the first pattern.
