How long does it take for a child's pupils to return to normal after dilation, and what should be noted?

Patient's question:

No

Doctor's answer:

There are many types of mydriatics. Generally, drugs that take effect quickly have a shorter duration of action and lower intensity; drugs that take effect more slowly have a longer duration of action and higher intensity. However, this does not mean that the effect of rapid dilation is inferior to that of prolonged dilation. In fact, the duration of time required for dilation depends on the different eye conditions of different populations. Teenagers have very strong accommodative abilities, and rapid-acting mydriatics often cannot counteract the accommodation of their eyes, which can easily lead to inaccurate refraction and unsuitable glasses. Therefore, slower-acting drugs should be used.
