Problems solved by technology

[0006] In order to overcome the shortcomings that most of the eye charts in the prior art are fixed on the wall, it is not easy to move flexibly, and the overly complicated symbols on the entire eye chart easily distract the attention of the testers. The technical problem of the present invention is to provide a flexible Mobile, and the symbols on the eye chart can be displayed separately, which is helpful for the tester to concentrate on the ophthalmic and convenient mobile vision test equipment

Abstract

The invention relates to vision testing equipment, in particular to vision testing equipment for ophthalmology department and convenient to move. The vision testing equipment is convenient for flexible moving, can display symbols on a visual chart and is conducive to a testee in focusing attention. The vision testing equipment comprises a bottom plate, supporting legs, a support, a box, a first bearing seat, a first rotating shaft, a roller, the visual chart, a motor and a worm, the supporting legs are arranged on front, rear, left and right sides of the lower portion of the bottom plate, thesupport is connected in the middle of the upper side of the bottom plate, and the top end of the support is connected with a box. The defect that visual charts are generally fixed on walls, thereby being inconvenient for flexible movement and the defect that complex symbols in the whole visual charts are prone to distraction of the testee are overcome, so that convenience is brought to flexible movement, the symbols on the visual chart can be displayed respectively, and convenience is brought to the testee to focus attention.

Description

technical field [0001] The invention relates to a visual acuity testing device, in particular to a convenient mobile visual acuity testing device for ophthalmology. Background technique [0002] The full name of ophthalmology is ophthalmology, and ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Common eye diseases include: central serous retinopathy, dry eye, night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia, retinitis pigmentosa, retinal detachment , myopia, hyperopia, needle eye, glaucoma, floaters, etc. [0003] With the popularization of mobile phones and computers, many people use mobile phones or computers for a long time, which greatly increases the frequency of eye diseases, and visual acuity examination is of great significance to the clinical diagnosis and treatment of eye dise...
