Embodiment 1

[0012] Embodiment 1: a kind of adjustable eye detection device, see figure 1 A parallel light parallel condenser cover 10 is sealed and connected to the rear side of the lighting tube 2, and a light source 9 is installed at the focal point of the parallel light parallel condenser cover 10. A bracket 1 is fixed outside the lighting tube 2 and the parallel condenser cover 10 . A convex lens 3 is sleeved in the lighting tube 2, a lens holder 6 is fixed on the outer edge of the convex lens 3, and an axial slide block 5 is evenly arranged radially on the outer edge of the lens holder 6.

[0013] see figure 2 Adjustment holes parallel to the axial direction are evenly arranged on the circumferential side wall of the middle part of the daylighting tube 2; the axial sliders 5 are respectively matched and installed in the adjustment holes. At the same time, an adjustment ring 4 is set outside the daylighting tube 2, and the inner wall of the adjustment ring 4 is threadedly connected...

Embodiment 2

[0017] Example 2: see figure 1 , the content is basically the same as that of Embodiment 1, the difference is: between the said daylighting tube 2 and the parallel condenser cover 10, an optotype groove 7 with an opening on one side is arranged, as image 3 , Figure 4 and Figure 5 Each shown visual mark 8 all can be movably installed in the visual mark groove 7. Therefore, a solution for flexible replacement of visual targets is provided to improve detection accuracy.

Embodiment 3

[0018] Embodiment 3: accompanying drawing is not drawn, and content is basically the same as embodiment 1, and difference is: the drive mechanism that is connected with described adjustment ring transmission is installed, and the control end of drive mechanism is connected with the output end of processor, and the signal of camera The output terminal is connected with the signal input terminal of the processor, so that the purpose of automatic control and automatic detection can be realized.

Abstract

The invention discloses an adjustable eye detecting device. According to the eye detecting device, a convex lens is sleeved with a lighting cylinder; an adjustable cover is adopted to control the convex lens for axial movement; a central hole is formed in the center of the convex lens; a video camera is mounted inside the central hole; a parallel light-focusing cover of parallel light and a light source are connected to the rear side of the lighting cylinder in a sealing manner; a sighting mark is arranged between the lighting cylinder and the parallel light-focusing shield. The eye detecting device can alter different positions of the sighting mark projecting on an eye, can realize the aims of dynamic adjustment and dynamic detection, as well as automatic detection, so as to provide sufficient detection standards for correct detection, can determine the maximum grade, the minimum grade and states according to the shading transition condition, and calls a data base for comparison to determine the healthy or sick degree of patients' eyes.

Description

technical field [0001] The invention relates to detection tools in the field of ophthalmic medical technology, in particular to a device for detecting eye diseases by collecting eye reflection information by controlling changes in the projection of an optotype on the eye. Background technique [0002] At present, most of the instruments used for eye detection are used to detect myopia or astigmatism. For example, in ophthalmology, there are professional machines for identifying the diopter of the eyes. Generally, such machines are also available in optometry places. The designated part lets you see a small picture through a small hole, and the machine will automatically adjust the distance of the picture so that it can be clearly imaged on the retina, and the diopter of the eye can also be measured in this way. However, for people with eye diseases, it is difficult to correctly detect and judge with a refractive instrument when the eyes are only partially abnormal in refract...
