Is it better for a 7-year-old child to have slow cycloplegia or fast cycloplegia?

Patient's question:

No

Doctor's answer:

Generally, after slow dilation for 3 times, a vision test can determine if the child has myopia, hyperopia, or astigmatism, as well as the degree. After slow dilation, the pupil remains dilated, and it takes about three weeks for the pupil to return to normal after stopping the medication. During this period, the child may experience symptoms such as blurred vision and sensitivity to light, and sunglasses can be worn outdoors. It is best to avoid close-up eye use during the dilation period.
