Last time we introduced you to the exterior momentum test, which we believe has been learned. What we've brought to you is a “method of cross-ring visual inspection”。

Cross-ring visual test function and principles

Cross-ring visuals can be detected: both eyes simultaneously visual, qualitative, quantitative and analytical insular, including horizontal and vertical insular

Horizontal and vertical eye-ring visual tests can be performed using red green glasses or a two-colour filter with the right red left green embedded in the integrated photocopy. Because of the principles of red and green, the right eye of the person being tested sees the red cross and the left eye sees the green double circle

Cross-ring visual inspection operational steps and methods

1. A far-reaching field test based on naked eyes or light。

2. The inner mirrors of the right vision hole are adjusted to the red filter and the internal mirrors of the left vision hole to the green filter。

3. Launch a cross-ring projector。

4. The examiner is advised to look at the sight of the eye, and if the cross-reference is located at the centre of the ring-view, the diagnosis is the correct eye; if the cross-reference deviates from the centre of the ring-view, the diagnosis is the invisible slash。

Cross-ring visual inspection

1. The quantified scope of the cross-cyclical visual marker test is the invisible tilt 4, which cannot be detected for the larger cavity, so some projectors do not have it。

2. The object of the inspection is a red green lens。

3. For persons detected with chromosomal impairments, detection may not be successful。

The crucifixor is not capable of detecting the oscillation of the rotation, since the red circa of the right eye can be seen after a two-colored red and green vision, although the approximate nature of the oscillation of the right eye of the person being measured can be judged in a general way. However, because of what is seen in the left eye, the green ring has no reference scale. So, no potential oscillation in relation to the left eye can be characterized or quantified, so the crucifixion mark cannot be tested for oscillation

That's all this is for this crucifix. I'll see you next time
