The main precautions for children’s eyeglasses fitting are to get the accurate refractive error through dilated optometry, and try to choose lighter weight lenses and eyeglass frames when fitting eyeglasses. 1. Pupil dilation optometry: Since the ciliary muscle inside the eyes of children is very strong in regulating function, if you don’t dilate the pupil and directly check the optometry, there will be a big error in the result, you need to use pupil dilating drugs to paralyze the ciliary muscle and then carry out the optometric examination in order to get the accurate refractive error. 2. Lens and frame material: in the examination and allocation of glasses, we should pay attention to try to choose a lighter weight of the lens and frame material, which can reduce the nosepiece of the spectacle frame on the root of the nose area of the skin pressure, to avoid the formation of localized skin depressions affecting the appearance. In addition, children should go to regular medical institutions for optometry and prescription.
