Multifunctional and portable visual function testing equipment

[0056] Vision Test:

[0057] The optical module 9 is lifted by the handle 8. At this time, the track 9.3 on the optical module 9 slides upward along the sliding seat installed on the front bracket 6, and when it reaches the designed position, it is limited by the stop mechanism 7 to ensure that the optical module 9 will not fall. fall. Reflector 5.4 on the reflective assembly 5 reflects the image formed on the small screen 3.2 to the human eye, and now pull pin 5.1 is in the Figure 7 The preset position 1 in is used to detect the vision function.

[0059] Color Vision, Stereo Vision, Contrast Sensitivity, Physiophia Detection:

[0060] Perform pixel adjustment, raise the pull pin 5.1 on the reflection assembly 5, the reflection assembly bracket 5.3 rotates in the bearing seat 5.2, wherein the bearing seat 5.2 has a bearing, and reaches the design position, and the pull pin 5.1 is automatically positioned on the rear support 4 , the automatic positioning process is: set the spring pressure pin, the pressure pin hole and the guide cone hole on the reflection component bracket 5.3, when the user rotates to the position of the guide cone hole, the spring pressure pin will automatically enter the pin hole through the guide cone hole , to achieve pin hole positioning. Pull pin 5.1 is in preset position 2, as Figure 8 shown. The naked-eye large-screen component 1 is switched from an initial small screen with 3.2 pixels to a large screen with 1.2 pixels to realize detection of color vision, stereo vision, contrast sensitivity, a

[0063] Eyesight detection: the optical module 9 is raised in the front bracket 6 by the handle 8, and when it reaches the designed position, it is limited by the limit mechanism 7 to ensure that the optical module 9 will not be misplaced.

[0064] The reflector 5.4 on the reflection assembly 5 reflects the image on the small screen 3.2 to the human eye through the lens 9.2 on the optical module 9, and the pull pin 5.1 is at the preset position 1, and the human eye sees the virtual image through the optical module 9 at this time , to achieve the detection of 5000mm vision function, such as Figure 9 shown.
