Embodiment 1

[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.

Embodiment 2

[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...

Embodiment 3

[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.

Abstract

The invention provides a multifunctional and portable visual function testing equipment. The equipment comprises a large screen, a small screen component, a reflective component, a rear bracket for fixing the small screen component and the reflective component, an optical module, and a front bracket for fixing the optical modules. The reflective component includes two mirrors that can rotate withthe mirror support, and the optical module includes two lenses that can slide up and down along the front bracket. The detection equipment of the present invention has the characteristics of high efficiency, high integration, and portability, adopts a common optical path design, and uses a reflection device to realize the adjustment of a pixel, and effectively reduces the space size of the equipment. The virtual imaging technology of the optical module is used to realize the detection of 5000 mm visual function. In addition, all the above operations do not require any auxiliary personnel, andcan independently complete 11 detection functions for vision, color vision, stereo vision, contrast sensitivity, heterotropia, flash fusion frequency, and the like at 300 mm and 5,000 mm viewing distances.

Description

technical field [0001] The invention belongs to the technical field of photoelectric instruments, and in particular relates to a multifunctional portable visual function detection device. Background technique [0002] In the field of modern medicine, the detection of human eyes has always been an important direction of medical development. Traditional visual function testing equipment takes up a lot of space, causing serious space waste. Due to the complicated inspection items of visual function, traditional visual function detection methods or equipment can only complete single, two or several visual function detection. Moreover, the detection method is complicated and usually requires multiple assistants to operate, resulting in a low degree of functional integration of the detection equipment and a long time for inspection. In addition, the detection equipment is heavy and not portable. Contents of the invention [0003] The purpose of the present invention is to pro...
