Problems solved by technology

Since the eye chart is fixed on the wall, the examinee and the examiner need to move multiple times according to the position of the eye chart and perform visual acuity measurement, and each time the position is changed, it is necessary to re-determine that the line of sight of the examinee should be in line with the eye chart. Parallel, and keep a fixed distance from the eye chart, very time-consuming

Abstract

The invention discloses an eyesight measuring method, an information control center device and a computer storage medium. The method is applied to at least one information control center device in communication connection with projector equipment. The method includes the steps: displaying at least two visual charts through a touch screen by the information control center device; detecting whetherthe visual charts are set in real time on the touch screen or not by the information control center device; controlling the projector equipment to project the set visual chart to a display terminal bythe information control center device and displaying the current chart on the display terminal if detecting that the touch screen sets one optional visual chart at the first time; controlling the projector equipment to project the visual chart set at the second time to the display terminal by the information control center device and displaying the replaced chart on the display terminal if detecting that the touch screen sets one optional visual chart except for the current visual chart at the second time.

Description

technical field [0001] The invention relates to the technical field of visual acuity measurement, in particular to a visual acuity measurement method, information control center equipment and a storage medium. Background technique [0002] Visual acuity is also known as visual acuity. The classic interpretation of visual acuity is the ability of the human eye to distinguish whether two points are separated. Clinically, it is more understood as visual acuity. In fact, visual acuity should be the ability of the human eye to distinguish the fine structure of objects. There are many ways to measure it, such as minimum visibility, two-point resolution, vernier vision and contrast sensitivity determination. But the most commonly used is the visual acuity measured by the eye chart. [0003] The eye charts used in China include international standard eye charts, logarithmic eye charts, and Lange ring eye charts. The eye chart is based on the principle of visual angle. Visual acui...
