Refractive amblyopia, most cases can be cured. Most refractive amblyopia is associated with hyperopia, accompanied by amblyopia, caused by abnormal fetal development in the womb, and the specific cause is unknown. If amblyopia in children can be detected between the ages of three to five and treated in a timely manner, most cases can be cured with a good prognosis. Treatment before the age of eight has better outcomes; treatment between 8-12 years old is less effective; there is no way to treat after age 12. The principle of treating amblyopic children is based on medical optometric prescription combined with effective amblyopia training, which primarily includes threading beads, puzzles, or using amblyopia treatment devices, etc. After amblyopia is cured, follow-up is required for three years to prevent recurrence.
