Whether or not amblyopia requires lifelong glasses depends on the specific circumstances of the amblyopia. High levels of hyperopia or myopia and large degrees of astigmatism often lead to amblyopia, while hyperopia decreases with age and some can be removed after amblyopia is cured. However, myopia and astigmatism generally do not get smaller and require glasses for life, but mild astigmatism can only be worn for fine visual activities such as reading and studying. The best time to treat amblyopia is before the age of 6-7. Because children are not very cooperative with examinations, they need to have their vision checked at the age of 3-4 years old. If the vision is found to be lower than normal, they need to have their pupils dilated for early detection of refractive errors. Amblyopia detected at this stage can be treated with glasses or coverings depending on the type of amblyopia, with functional training to assist amblyopia, and regular eye refraction checks at regular intervals to adjust the program. In the best period of treatment before 6-7 years old, if treated effectively, vision is expected to improve gradually, and when both eyes are balanced, or vision reaches normal level, glasses can be removed gradually around 12 years old. Therefore, if amblyopia is diagnosed early and treated correctly during early childhood, glasses can be removed after correction. If you miss this period of visual function development, the resulting amblyopia is not easily corrected and requires lifelong glasses.
