Abstract

The invention discloses a vision detection device. The vision detection device comprises a combination table, wherein a bottom plate is fixedly connected to the bottom of one end of the combination table through bolts, a fixing frame is arranged at the top end of the bottom plate, a sighting mark adjusting and disarranging mechanism is arranged at one end of the fixing frame, and the sighting mark adjusting and disarranging mechanism comprises an extension plate, an electric telescopic rod, a moving plate, a stand column, a vertical plate, a screw rod, a knob, movable blocks, a supporting plate, a sighting mark frame, a fixing plate, a rotating block and a character table. The vision detection device is scientific and reasonable in structure and safe and convenient to use; the sighting mark adjusting and disarranging mechanism is arranged, the electric telescopic rod pushes the extension plate and the moving plate to move, the position of the sighting mark frame is changed, and therefore the proper viewing distance can be adjusted according to needs; and in addition, the screw rod is driven to rotate through the knob, the two movable blocks are pushed to move, then the supporting plate is cooperatively used to push the sighting mark frame and the vertical plate to move, the height of the sighting mark frame is changed, and the adaptability of the device is improved.

Description

technical field [0001] The invention relates to the technical field of vision detection, in particular to a vision detection device. Background technique [0002] The full name of ophthalmology is "eye disease specialist", which is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Ophthalmology generally studies vitreous, retinal diseases, optometry, glaucoma, optic neuropathy, cataract, etc. eye diseases; [0003] However, when the existing devices perform visual acuity testing, the arrangement and direction of the word table patterns are fixed, which are easy to be memorized by the testers, and the phenomenon of being blind appears, which affects the accuracy of the detection. Therefore, we have to avoid these situations. Given the above technical problems, it is indeed necessary to provide a visual inspection device to overcome the defects in the prior art. Contents of the invention [0004] The prese...
