technical field

The invention relates to an auxiliary vision test device for ophthalmology, in particular to an easy-to-adjust auxiliary vision test device for ophthalmology.

Background technique

The full name of ophthalmology is "ophthalmology specialist". Ophthalmology is a discipline that studies diseases that occur in the visual system, including the eyeball and its associated tissues. Common ophthalmic diseases include: central serous retinopathy, dry eye, and sympathetic ophthalmia. , night blindness, blindness, amblyopia, astigmatism, trachoma, cataract, diabetic retinopathy, conjunctivitis, presbyopia, color blindness, heterochromia iris, retinitis pigmentosa, central retinal artery occlusion, retinal detachment, myopia, hyperopia, pin eye, snow blindness, Chalazion, glaucoma, floaters, etc. An eye chart is a chart used to measure vision. The visual charts used in China include: international standard visual chart, visual chart logarithmic visual chart, etc. In terms of function, there are near vision chart and distance vision chart. The eye chart is based on the principle of viewing angle. The inspection vision is generally divided into two categories: distance vision and near vision. The international standard vision chart is mostly used for distance vision. This chart is composed of "E" characters with different openings and directions. The visual acuity chart used in medical testing mainly examines the central vision, that is, the foveal visual acuity of the macular region of the retina, so that the initial situation of visual function can be easily and quickly understood, which is of great significance to the clinical diagnosis and treatment of eye diseases.

Existing patients perform vision tests in a standing state, but it is difficult for frail patients to stand for a long time, which makes it difficult for frail patients to perform vision tests normally.
