Color field of view and determination of blind spots
1. Teaching purpose To determine the range of various color fields of view and the location of blind spots, learn to use the perimeter meter
2. Experimental program
2-1 Preparation.
2—1—1 Prepare the visual field drawings, colored pencils, and single eye masks. Place the visual field drawing on the corresponding place on the visual field meter and learn how to record on the drawing.
When recording, it is opposite to the left and right and upper and lower directions of the reaction of the subject.
2—1—2 The subject used the right eye mask to cover the right eye, put the chin on the bracket, and adjust the distance. Keep your head in position when your eyes are close to the stand. The subject used the left eye to look at the white spot in front of it. Subjects are required to report that the color appears or disappears in the field of view. The subject's line of sight should always look at the white point in the center of the field of view. It is required to use only the residual light of the eye to see if the colored spot appears or disappears.
2—l—3 During the measurement process, the position of the field of view arc can be 900, 450, 1350, and 1800, respectively.
2-2 formal experiment.
2—2—I The main test is to take the visual field arc track to the horizontal position. Put a red stimulus point on the right side of the arc track near the gaze point,
The main test will slowly move the red stimulus from the inside until the subject does not see red, and then record the location of the red stimulus.
Then the main test will move the red stimulus from the outside case to the gaze point until the subject just sees the red, record the angle of the stimulus position, take the average of the two, and click on the map on the visual field. It should also be noted that when the red stimulus is from the inside to the outside or from the outside to the inside when the right experiment is performed, the red color suddenly disappears and reappears. The position where the red suddenly disappears and the position of the reproduction is the position of the blind spot, and the position of the blind spot is also recorded. On the drawing.
2—2—2 Place the field of view track to the following position to determine the range of red field of view: 900, 450, 1350 and other different angles. The first model network to organize the article, the copyright belongs to the original author, the original source.
2—2—3 The visual field of each of yellow, green, blue, and white is measured according to the above-mentioned program for measuring red field of view.
2—2—4 After each color has finished an angular position, rest for 2 minutes. Note that the position of the head should be unchanged after each break.
3. As a result, each color field of view and blind spot position is drawn on a drawing.
4. discuss
4-1 How to arrange the order of various color fields of view? The location and size of the blind spot in the field of view and on the web.
4-2 What is the color change before the vision disappears?
4-3 Is the color field of view fixed? What conditions does it change?
