Vision Test Chart Red and Green Card

Training Method:

1. The trainer wears red and green glasses and fixes the same set of cards with variable vector images on the training bracket at a distance of 40 cm to ensure the stability of the sliding.
2. Red and Green Card Two cards with the same red and green grouping numbers are used as a group for training. No. 01-03 gradually increases the training difficulty.
3. Aim the green card scale pointer at the zero scale of the red card, fuse within 3-5 seconds, maintain a clear image, and maintain the fusion state for 10 seconds.
4. Pull Red and Green Card at a constant speed by an amount of 2, and gradually increase the training difficulty. Pull the red card to the right for collective training, and the lower scale is the collective separation amount; pull the green card to the right, and the upper scale is the scattered separation amount; the collective reaches 30△BO , the spread reaches 15△Bl.

• Group 01 performs peripheral fusion training. After fusion, you will see a large circle surrounded by four small circles.
• Group 02 trained peripheral fusion and stereopsis. After fusion, they saw two large circles in the middle and four small circles around them. The rings had a three-dimensional feeling (convex or concave). As the gaze time increased, the three-dimensional feeling became more and more obvious. The stronger.
• Group 03 trained peripheral fusion, stereoscopic vision and foveal gaze. After fusion, they saw two large circles in the middle and four small circles around them. The rings had a three-dimensional feel (convex or concave), and the □, X, and O On the same vertical line, as the gaze time increases, the floating feeling of the central ring becomes stronger and stronger, and "x" also feels floating.
• When training together, the fused image will become closer and smaller; when training separately, the fused image will become farther and farther away, becoming larger and larger.
