Description

시력측정기(비디오 VIDEO장치)Visual acuity meter (video video device)

제1도는 본 고안의 내부 구조평면도.1 is a plan view of the internal structure of the present invention.

제2도의 1 및 2는 시력표시판 단면도.1 and 2 are cross-sectional views of the visual acuity display plate.

제3도는 본 발명의 사시도이다.3 is a perspective view of the present invention.

본 고안은 시력측정에 있어서 재래식 즉 1909년 제11회 국제안과학회에서 제정한 것을 각국에서 각자가 란톨드환을 기준으로 하여 붕어, 나비, 수자차등을 기입하여 각자의 의견에 의한 시력표 한장에 작성하여 5m거리를 기준으로 하여 3m, 2.5m등의 거리에서 보아서 2.0-0.1까지 시력표에 의하여 측정하게 한 것으로, 시력표 작성자의 이름을 따서 석원식시력표, 산지식시력표 정상식시력표, 중천식시력표, 경응식시력표 등등 수 없이 많으며, 이 재래식을 원리에 맞게 정리하여 간편 기계화하여 과학적으로 진보시킨 것으로 물리적 또는 정확한 계산에 의하여 1m거리로 단축시킨 것으로 그 원리는 동그라미(環)을 5m거리에서 지름 7.5mm동그라미선 1.5mm동그라미끝과 끝의 띠운사이 1.5mm의 시표(視標)가 띠운사이 시각이 1'(분)을 기준으로 하여 시각이 2'(분)인 시에는시각이 5'(분)인 시에는가 되는 것이다.The present invention was established by the 11th International Ophthalmological Society in 1909 for the measurement of vision. 3m, 2.5m, etc. based on the distance of 5m, measured by the sight table up to 2.0-0.1, after the name of the eyesight table vision table, mountain vision table, normal vision table, asthma vision table, Kyung Eungsik Sight table, etc. There are countless numbers, and this conventional method is summarized according to the principle, and it is a simple mechanized and scientific advance. The principle is to shorten the distance to 1m by physical or accurate calculation. When the 1.5mm mark between the end of the 1.5mm circle and the end of the band is 2 '(minute) based on 1' (minute) Is If the time is 5 ' To be.

여기에서 주의할 점은 약시인데 약시는 0.3-0.04, 0.06-0.02=준맹, 0.02이하는 맹이된다. 이 계산법은 0.08의 크기를 산출하는 방법은 0.8≒10=0.08이되고, 0.8의 계산법은 위 0.08의 역수임으로 0.08×10=0.8이 된다.It is important to note that amblyopia is 0.3-0.04, 0.06-0.02 = consistency, below 0.02 becomes blind. In this calculation, the method of calculating the size of 0.08 is 0.8 ≒ 10 = 0.08, and the calculation method of 0.8 is the inverse of 0.08, which is 0.08 × 10 = 0.8.

그리고 길이의 5분의 1로 축소할시에는 넓이는 25분의 1로 축소된다. 넓이=s, 길이=r, And when it is reduced to one fifth of its length, its width is reduced to one fifth. Width = s, length = r,

이와같이 원리에 의한 정리한 정밀한 계산에 의한 500록스(los)를 기준으로 한 란톨드환을 1m거리에서 사용하여 시력을 측정할 수 있게한 시력측정기에 도수(Dioptrie) 측정기(Visiontester)와 비디오(ViDEO)를 조립 장치한 것을 특징으로 하고 있다.In this way, a vision tester that can measure eyesight using a lanthold ring based on 500 lox at a distance of 1 m by precise calculations based on the principle, a vision tester and a video tester (ViDEO) It characterized in that the assembly device.

다음 도면에 의하여 구조 내용과 사용법을 설명하면, 1도는 평면도로서 1은 대안렌즈이고, 2는 2도의 1과 같은 모양의 렌즈도수 별로 끼워 있는 회전기이고 3은 대물렌즈이고, 4는 2을 회전시키는 조졸기(control)이고, 5는 2도의 1모양으로 0.04-2.0까지의 표시되어 있는 란톨드환 회전판이고, 6은 5을 회전시키는 조졸기이고, 7은 TV, 또는 모니타(monitor)를 부착한 곳이고, 8은 비디오(ViDEO)을 장치한 곳이고, 9는 조졸기와 2 또는 5를 각기 연결한 축(shaft)이고 10은 2도의 2와 같은 란시(亂視)표를 부착한 곳이다.Referring to the structure and use of the structure according to the following drawings, 1 degree is a plan view, 1 is an alternative lens, 2 is a rotator that is fitted according to the lens degree of the same shape as 1 of 2 degrees, 3 is an objective lens, 4 is rotated 2. 5 is a lanthande ring rotating plate indicated by 0.04-2.0 in a shape of 2 degrees, 6 is a solving machine which rotates 5, and 7 is a TV or a monitor. One place, 8 is the place where the video (ViDEO) is installed, 9 is the shaft connecting the sleeper and 2 or 5, respectively, and 10 is the place where the Lanshee table is attached, such as 2 of 2 degrees. to be.

이와같이 과거 재래식 시력측정표보다 물리적, 과학적으로 정확히 측정할 수 있는 다목적 기구 장치로 진보적이고 생산적인 현대식으로 유용하게 고안한 렌즈도수 및 비디오 장치인 시력 측정기이다.As such, it is a multi-purpose instrument device that can measure physically and scientifically more accurately than conventional optical eye charts.
