1. Those who have been prescribed glasses need to wear glasses for treatment. Wearing glasses itself is an important means of treating amblyopia. Therefore, it is necessary to insist on wearing glasses. 2. Generally, treatment is given once a day, with 2-3 functions trained each time. If you have a serious condition, you can train 2-3 times a day, with an interval of 2 hours or more between two adjacent training sessions. It is best to train different functions on two adjacent days, referring to the training schedule equipped with the instrument, or to the function training specified by the doctor (it is best to do a grade vision-contrast sensitivity training every day). You can add any one function to the training schedule of the instrument to enrich the training content.3. Each function requires only 5 minutes of training per eye or extended training time as prescribed by the doctor (except for the posterior image).4. Grade vision-contrast sensitivity training is the function with the best effect on vision enhancement, which is difficult to train, but good results can be achieved as long as the training is adhered to.5. Each instrument comes with an internal visual acuity. But this visual acuity table and 5 meters vision has 1-2 row deviation, when the visual acuity up to 0.9 or with myopia, high farsightedness, deviation may be larger, for reference only, can not fully represent the 5 meters vision. However, if a child can see 0.5 on the in-camera visual acuity scale today and 0.7 next month, it does not necessarily mean that the child’s vision is 0.7, but it does mean that the child’s vision has improved. Finally, the principle of amblyopia treatment is early detection and early treatment, and the treatment effect is better before the age of 10. Parents should supervise their children for long term amblyopia training and regular follow-ups to have a better prognosis.
