Ophthalmology vision examination device

Abstract

The invention relates to the technical field of vision examination, and discloses an ophthalmology vision examination device which comprises a base and an L-shaped vertical plate, a rotating plate is arranged at the position, located on the inner side of the vertical plate, of the upper surface of the base, a vision examination table is arranged on the front surface of the rotating plate, a touch screen is arranged on the rear surface of the rotating plate, and a height measuring mechanism is arranged on the outer side face of the vertical plate. A plurality of lamp panels are distributed on the inner side of the rotating plate corresponding to the vision examination table, a trigger strip is arranged on the surface of each lamp panel, and rotating shafts are arranged in the middle of the upper surface and the middle of the lower surface of the rotating plate. According to the device, the rotary type rotating plate design is adopted, the lamp panel of the visual acuity examination table adopts the independent trigger type design, the illusion that light of a traditional visual acuity examination table illuminates all E characters, and a testee is prone to being in a mess is solved, the visual acuity examination table has multiple functions of visual acuity examination, color blindness examination and height examination, and the integrated design is achieved. Not only is the cost saved, but also the inspection time is shortened, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vision inspection, in particular to an ophthalmic vision inspection device. Background technique [0002] Ophthalmic vision examinations are generally tested by doctors using vision charts, which are charts used to measure vision. Functionally, there are near vision charts and distance vision charts. The vision chart is formulated based on the principle of visual angle. It is generally divided into two categories: distance vision and near vision. The international standard eye chart is mostly used for distance vision. This chart is composed of 14 rows of "E" characters with different sizes and opening directions; [0003] The existing eye charts are generally fixed in the ophthalmology room, not only have single functions, but also have relatively large limitations. They are only used for visual inspection, and when the existing eye chart is checked, all the "E" will be displayed when the light is on. Th...

Problems solved by technology

[0003] The existing eye charts are generally fixed in the ophthalmology room, not only have single functions, but also have relatively large limitations. They are only used for visual inspection, and when the existing eye chart is checked, all the "E" will be displayed when the light is on. The words are illuminated. When the tester refers to the corresponding "E" word, since all the "E" words are all lighted up, it is easy to cause the illusion that the tester is dazzled, resulting in slow recognition speed or wrong recognition.
