Due to dilated pupils, children may feel photophobic and have difficulty seeing near. (1) Avoid bright light stimulation, especially strong sunlight, and wear a brimmed hat or sunglasses outdoors. (2) During pupil dilatation, children should be watched carefully to avoid bruising due to blurred vision. (3) Since the purpose of dilating the pupil is to relax the ciliary muscle, do not use the eyes at close range during dilatation, such as reading books, watching TV or using a computer. (4) In a very small number of children, if symptoms such as flushing, thirst, fever, headache, nausea, etc. occur after pupil dilatation, they should be considered as adverse reactions to atropine and should be discontinued immediately. (5) The time it takes for the pupil to return to normal varies from child to child. (Generally, it takes 4-6 hours for fast dispersion and 3 weeks for slow dispersion)
