Digital visual acuity detection device

This creation is related to a digital visual acuity detection device, especially a digital visual device with small volume, no field limitation, different detection functions, no more human factors, and more reference value. Detection device.

According to the examination, eyesight examination is common in general hospitals, health centers, clinics or optical shops. It mainly uses visual acuity chart or vision tester to perform his or her conscious vision measurement according to the instructions of the examiner. Among them, he feels that the inspection method is utilized. A special vision measuring device that measures the refractive index of the eyeball and then verifies and determines the visual acuity according to the actual lens used; as for the conscious inspection method, the visual inspection table using the C-ring or the E-target is specified by the examiner. The symbol is asked to answer the subject, and the subject's vision is determined based on the result of the answer.

At present, the most commonly used C-ring or E-visual visual acuity checklist is used together with a light board machine, and the subject is at a position outside the predetermined distance, using the gesture or answering the light board according to the direction of the inspector. The direction of the opening of the C-ring or the E-marker can achieve the expected inspection effect. However, since the symbol size on the lamp board is fixed, it must be carried out at the site that meets the inspection distance in practical applications, so that There are more restrictions on the use.

With the popular use of computers, the use of visual inspection remote control devices in conjunction with computers and LCD screens or projectors has enabled the construction of a digital visual inspection system that overcomes the distance constraints of the venue by adjusting the symbol scale; As the age of myopia decreases, the E-visual, C-ring and even digital visual markers may be an unknown text for young children, for most For young children, it is often unclear what the meaning of the symbols displayed on the screen is, and it is impossible to cleanly answer the symbolic signs they see in accordance with the expected pattern.

Furthermore, the similar visual inspection system is still subjectively judged by the examiner according to the content of the subject's response. The judgment method is relatively inconsistent, and the inspector may also be exposed to the environment. The murmur or interference caused by other human factors, misjudging the content of the respondent's answer, not only affects the reference value of the visual acuity test results, but also causes the subject's rights and interests to be seriously impaired.
