In the outpatient clinic often encounter some parents on the child’s dilated optometry questions, do not know how this is, so worried. In fact, there is no need. Children’s eyes are more adjustable than those of adults, and they can often “hide” part of their prescription, so if you want to find out the real prescription, you need to order a dilated ointment to dilate the pupils and then take an eye test. This process is done twice a day in each eye for children under 12 years of age for three days, with the eye exam repeated on the fourth day. It takes about 20 days for the pupil to recover after stopping the medication, and on the 21st day, you go to the hospital to try the film according to the optometry after dilating the pupil, which is the child’s true prescription. During this period, the child will be a little blurred to see close, do not worry, will be fully recovered. Only for children who have gone to school, it will affect reading and writing. Try to choose the summer and winter vacations. In older children over 12 years old, you can order drops at the hospital and have an eye test after 40 minutes.
