Amblyopia is a developmental disorder, and the younger the child, the better the outcome and the higher the cure rate, while the cure rate is basically hopeless in adulthood. 82%-83% of children are cured at the age of 7, and 46%-64% of children older than 7. After the age of 13, when the neural pathways of the eye-cortex are basically well developed, there is less and less hope for vision improvement and more and more difficulties in treatment. The key to improving the cure rate is early detection, so how can we detect children with amblyopia early?

Kindergartens should make vision checkups a regular checkup for nursery and class start-ups, and in addition, take a vision checkup at least 1-2 times a year, and contact parents promptly if problems are found.
