Description

Technical Field

[0001] The invention relates to the technical field of medical devices, in particular to a portable vision testing box. Background Art

[0002] Most of the existing eye charts are paper eye charts and light box eye charts. Paper eye charts are easy to carry and can be used by sticking them on the wall. However, when using paper eye charts for vision examinations, sufficient light is required, otherwise it is difficult to reflect the patient's more realistic vision examination results. The light box eye chart has a light source in the light box that can illuminate the observation board of the eye chart to increase the brightness of the observation board, so it does not rely on ambient light when using the light box eye chart. However, light box eye charts are usually large in size, and components such as the observation board are fragile. Especially for doctors working in remote mountainous areas who need to travel long distances to visit patients, most of the existing light box eye charts are not convenient to carry.
