1. Sit at the desk, and the line of sight is flush with the line of sight in the middle of the character card (the degree and distance between the character card and the double mirror are carried out under the guidance of a professional trainer).

2. Train one eye first, then train two eyes; First look at it with a convex lens, then look at it with a concave lens (convex lens magnifies the object image and relaxes the ciliary muscle; Concave lenses reduce the object image and make the ciliary muscles tense)

3. Cover your left eye with a mirror cloth, aim the mirror ring at the center of the glasses, start with the first character, read the visual target aloud after seeing it clearly, then flip the double mirror, look at the second character again, and so on, until you finish reading 40 characters (period: one side is clear, the other side is blurred as a normal phenomenon, and the blurred side is difficult, but you can't skip it, so you must make sure to flip it after seeing it).

4. After seeing the right eye, rest for 1-2min and then change to the left eye training; After that, take a rest 1-2min for eye training (whether it is necessary to train eyes, listen to the optometrist's opinion according to the actual situation of patients).

As time goes on, training will become easier and easier. When you feel that the positive and negative speeds are similar, you can do a test with the word E, and then change the next word after the test reaches the standard, and so on.

6. The whole process is from easy to difficult, so don't rush for success. Train and record every day.

7. Conventional visual training is family training for 5 days a week and intensive training for 2 days in the hospital, which is arranged according to individual circumstances.
