pym:Hi pym,Normally the first time the spectacle power is checked at a doctor's clinic, eyedrops will be used to dilate the pupil and relax the focusing muscle to make sure the child is not 'overfocusing', since this might cause a child to seem more shortsighted than he/she really is. This is especially true for the very young children less than 7-8 years old, and serves as a baseline.
For follow up, the spectacle power can be checked first without eyedrops and then compared with the previous measurement with eyedrops. If there is no big change in spectacle power, especially for the older kids, then there is no need to put eyedrops again. If however, the new measurement is surprisingly different (eg the shortsightedness seems to have gone up by a lot), sometimes it is a good idea to repeat the measurement with eyedrops again.
In short, for review/follow up, the dilating eyedrops are not always needed.
Thanks for yr prompt response. My case is my child just has never wear spec and HPB has arranged normal health checkup n eye test for P1 students. My child last yr in K2 sch, her eye checkup is ok. No need to wear spec. N my child got a letter from HPB to hv further eye assessment at Student Health Ctr @HPB bldg. My child got eye test at sch result is 6/12, 6/18! Same diagnosed as sembgal's kid n I hoped it diagnosed wrongly as in sembgal case. The refraction clinic did not put on eye drop at all n I cfm witj my child. The test took 15mins or so. N came with the result that my child is myopia n asti! Wondering how accurate the test is? Shld I seek pte optometrist for 2nd opinion?
