Children are usually allowed to do homework after 4 hours of rapid pupil dilation, but are usually not allowed to do homework after 4 hours of slow pupil dilation.
Dilated pupil examination is through the ciliary muscle paralyzing agent method to dilate the pupil, after relaxing the eye regulation, the measured refractive error is more accurate, dilated pupil also helps to observe the structure of the fundus of the eye. If a child uses a short-acting ciliary muscle paralyzing agent such as compound tropicamide eye drops to dilate the pupil quickly, the pupil will usually return to normal in 4-6 hours and the child can begin to do homework.
If the child’s pupils are dilated slowly with drugs such as atropine sulfate ophthalmic gel, the dilated pupils usually take about 3 weeks to recover. Four hours after dilation, the child’s pupils have not returned to normal, so he or she cannot do homework normally.
It is recommended that children follow the doctor’s instructions for care after dilation, regular checkups, and timely consultation when discomfort occurs.
