Description: Product Usage: Used for jumping fusion training, can be used to evaluate the stability of binocular fusion For people: ty in spreading function, and stereoscopic vision disorder There are three sets of training cards: 1. Morgan Color Fusion Card 2. Bottom and outside prism type-BO-A series 3. Bottom inner prism type-BI-A series A: Use BO bottom wild cards for collective training 1. The training card board is fixed at the position of the scale "0", and the BO bottom and outer cards are placed on the card board, and the forehead is close to the bracket by adjusting the comfortable angle. 2. The right eye should see the right R and the image, with a small dot above the number. The left eye should see the left L and the image with a small dot below the number. 3. Observe with both eyes at the same time, first stare at the two images on the upper part of the card until they merge into a single and clear image, hold for 5-10 seconds. After the images are fused, you can see that the numbers around the image have a floating feeling, R and L are in the same box, and there are small dots above and below each number. 4. Move your eyes to watch the two images in the lower part of the card and merge them. The observed phenomenon is the same as the upper part of the card. 5. Alternately fuse the upper and lower pictures in turn. After each picture is fused, hold for 5-10 seconds, and alternately fuse 5-10 times. During this process, a single clear image is always maintained, and the floating feeling gradually increases with the increase of gaze time. enhanced. Go to the next page to repeat the training with increasing difficulty when finished. 6. If fusion is difficult, move the card towards the eye to reduce the difficulty. After the "0" scale can be completed, the card can be moved away to increase the difficulty. B: Use BI bottom inner card for spread training The training steps of the bottom inner card are basically the same as the bottom wild card, the difference is: 1. At the beginning of each card, first look at the two images below, and then look at the upper image after fusion, and so on alternately. 2. If the fusion is difficult, you can move the card farther to reduce the difficulty; after the "0" scale can be completed, you can move the card closer to increase the difficulty.
