LCD Vision Meter Function




LCD vision meter, also known as automatic electronic vision tester, as the standard arrangement in line with the new national vision standards. This vision table for children, adolescents or automatic electronic vision examination of the general physical examination, visual barrier screening and ophthalmology and optometry clinical diagnosis and treatment, academic, scientific research, teaching and audition and other aspects of vision determination. Especially for the air force recruitment examination of visual inspection, LCD Visual Acuity Chart to solve the medical staff command, evaluation, recording, statistics and other work on the results of the results, so that the results more just and reasonable.

LCD vision meter

First, the current vision table light box as the direction of fixed, but also need to direct the use of medical staff command, as the direction of the standard easy to remember, LCD Visual Acuity Chart medical staff command to determine the difference, will affect the accuracy of the results, especially in physical examination, medical staff The workload is very large. LCD vision meter can be set to check the requirements of each examineer fair and reasonable; each examiner, left and right eye inspection as the direction of the standard are not the same, put an end to the direction of the end of the possibility of visual; the results of scientific and accurate.

Second, the LCD visual acupuncture table, LCD Visual Acuity Chart also known as automatic electronic vision checker, as the standard arrangement in line with the new national vision standards. This vision table for children, adolescents or adults in general physical examination, visual barrier screening and ophthalmology and optometry clinical diagnosis and treatment, academic, scientific research, LCD Visual Acuity Chart teaching and audition and other aspects of vision determination. Especially for the air force recruitment examination of visual inspection, to solve the medical staff command, evaluation, recording, statistics and other work on the results of the results, LCD Visual Acuity Chart so that the results more just and reasonable.

Third, automatic electronic vision set of precision, convenience, versatility and other advantages in one of the automatic anti-cheating visual table. Simple operation process: select the test items - credit card - ready - detection - automatic report - the results of printing - storage. LCD Visual Acuity Chart The whole process without medical personnel command, greatly reduce the workload of medical staff 2 and the traditional visual light box light box difference

First, as the standard direction

Computer generated as standard, the size of accurate, random direction, no wear, long-term to maintain.

Second, glowing

Brightness is good, luminous uniform, as the standard contrast.

Third, reliability

Random set inspection rules, instrument rules check, reasonable and fair, LCD Visual Acuity Chart no medical staff due to command, evaluation of the results.

Fourth, function

The logarithmic visual acuity chart, the logarithmic visual scale, the logarithmic visual acuity chart, the logarithmic visual acuity chart, the C logarithm, 100%, 50%, 10%, 5% Logarithmic visual scale and so on.

Five, operation

Personal information automatically entered, automatically random as standard, intelligent judgment test results, to solve a large number of medical staff workload.

Sixth, check the results

Automatic printing, storage. LCD Visual Acuity Chart And according to different instructions screening, export; retrospective inspection process.

Seven, network transmission

Test results can be transferred to the remote database through the network, convenient and quick.

Eight, installed to carry

Easy to carry, easy to disassemble.

3 classification of visual acuity

Usually there are two kinds of visual acuity, that is, near vision and near vision. The general design standard check distance is 5 meters, measured by the human eye in a completely natural state of vision (ie, far vision), also known as static vision. And the near vision table (that is, LCD Visual Acuity Chart we usually check the vision used by the small visual acuity chart) is measured by the human eye on the distance (generally 30 cm as the standard distance) the ability to distinguish the target, because this process requires eye adjustment ( That is, automatic focus) participation, so near the visual acuity of the human eye is measured near vision, also known as dynamic vision. Application of mydriatic mydriasis, due to eye adjustment (ie, auto focus) ability of some or almost all of the loss, so near vision is generally poor.
