Description
Technical Field
The invention relates to the technical field of vision detection, in particular to a multifunctional vision detection box.
Background
In the prior art, a paper visual chart or a lamp box is generally used as an inspection tool for daily visual inspection, different visual charts and equipment are needed for special visual and visual function inspections such as contrast sensitivity, color vision, dazzling light, stereoscopic vision, infant visual inspection and the like, switching is complicated, errors are easily generated in result recording, and manual conversion is needed among different visual results.
The defects of the prior art in the visual and visual function examination include:
1. errors are easily generated by artificially estimating the detection distance
The traditional visual acuity test is divided into short-distance visual acuity test and long-distance visual acuity test, the distance between a patient and an eyesight test chart needs to be manually changed, and the distance is manually estimated and has great uncertainty, so that the accuracy of a result is influenced.
2. Need to autonomously select a switching checklist
The traditional visual acuity and visual function examination needs to be replaced by different examination charts, such as a near vision chart, a far vision chart, an F.A.C.T contrast sensitivity visual chart, a achromatopsia and weakness detection card, a three-dimensional detection card, a dazzling light detector, a DVA and KVA dynamic visual acuity detector and the like, while for infants, cartoon-shaped visual acuity charts exist, so many detection devices bring many unnecessary troubles to clinical work, such as maintenance of a paper version detection card, time waste of detection item switching, occupation space of numerous detection devices and the like.
3. The traditional visual chart has crowding phenomenon which affects the investigation of the amblyopia patient
When there are too many objects around the visual target, it will affect the recognition of the central visual target and make the detection result lower, especially in the amblyopia patient, the common visual chart may have lower vision because all visual targets are on the same visual chart, and the final inspection may need to be performed with the detection of the single visual target, but the problem is that different inspectors have different experiences, and some people may ignore the possibility of weakness and not continue the inspection with the single visual target.
4. The traditional vision test mode is fixed, and can be recited in advance
Because can not change check out test set, so there are drawbacks such as reciting in advance in traditional check out test set, mislead the inspection personnel and draw wrong result.
5. Different inspection equipment has different result expressions and needs manual conversion
Common expression patterns of vision are: score (20/20), decimal (1.0), logMAR (0.1), 5 score (5.0), and the conversion between different expression methods (simple function equation) can be performed, but it is very inconvenient, especially when trying to use the test result of the patient for scientific research, the result can only be performed in the form of logarithmic record or 5 score record.
6. The traditional vision and visual function test result is manually recorded
The traditional vision and visual function detection is a manual recording result, so that data information is not convenient to store, deviation and recording errors of left and right eyes easily occur, the accuracy requirement on the vision inspection of some disease patients (such as intraocular lens measurement before cataract operation) is higher, and the manual recording is difficult to meet the requirement.
7. The fixed height of the traditional visual chart can not be adjusted
Most of the traditional visual charts are light boxes or paper-version visual charts which are fixed on a wall at a certain height and cannot be adjusted, and the standard visual detection needs to be matched with the sitting height of a patient (for example, an adult with the height of 190cm and a pupil with the height of 120 cm).
8. Traditional contrast sensitivity visual chart is too mechanical
A conventional contrast sensitivity eye chart (f.a.c.t) contains 5 rows (spatial frequencies of 1.5,3,6,12,18cpd), each row having the same spatial frequency but comprising 9 different contrasts (increasing from 0.6log level by 0.15log unit to 2.26log level), the contrast sensitivity function curve of a patient being obtained by sequentially reporting the direction of the optotype stripes from top to bottom, from left to right, whereas the function curve obtained in this way is a broken line graph, is not a smooth curve, and may be ignored when patient variations are not obvious.
