Question

After 21 days of myopia correction, I tested my child’s vision and it seemed worse than before the correction. Before the correction, the uncorrected and corrected vision was about 0.6, but now with glasses it’s only 0.4, and without glasses, the vision is barely visible.

Answer

The symptoms you described are too general, and without a detailed examination of your child’s current prescription, it is difficult to make a specific diagnosis. It is also possible that the child’s vision has not fully recovered after the myopia correction. It is recommended to have another examination after two weeks. If there are any issues with your child’s vision, it is necessary to undergo relevant examinations at a regular hospital. Never seek treatment at an unqualified optical shop or medical facility.
