My child is four and a half years old and recently noticed that he was squinting when watching TV and sometimes he was looking upwards with his head down, so he went to the eye hospital for an examination. The results of the examination: astigmatism amblyopia left eye 800, right eye 700 degrees. The doctor diagnosed congenital anisometropia, which needs to be corrected with glasses for two months, and the current prescription is 300 degrees. I would like to ask: How many ways are there to treat this condition, which is the best treatment, and what are the effects on the child. Also, what effect can be achieved with the treatment. Thank you!
