You must have a dilated eye examination for childrens glasses. When children have poor vision, they should not blindly use the method of inserting lenses for optometry. Computer optometry cannot be used.

Because of non-dilated pupils, both inserted lens optometry and computerized optometry are inaccurate, making it difficult to detect issues such as amblyopia, strabismus, and astigmatism in children. Of course, to avoid delaying learning, it is recommended to have a dilated eye examination during the child's vacation.

A suitable pair of children's glasses frames is equally important for protecting children's vision. Some children feel dizzy after wearing glasses for a while, and their eyes become tired after reading for a while. One of the reasons is that the glasses frame is not suitable.

The suitability of the frame depends on whether the center of the pupil after wearing the glasses is aligned with the optical center of the lens. If the frame is too large or too small, the center of the pupil of the eye is not aligned with the optical center of the lens, which can cause discomfort after wearing glasses. If the deviation is too large, long-term wearing of glasses can also lead to strabismus.

When prescribing glasses, it is necessary to measure the distance between the pupils and choose a suitable children's glasses frame for the child based on the distance between the pupils and the width of the face. Some parents choose frames for their children based on personal preferences, especially adult frames, which is very inappropriate.

Because after the development of the adult nasal bone, the bridge of the nose is high, while in children, the bridge of the nose is low. Wearing an adult frame, the distance between the lenses and the eyes is far, which also affects vision. Therefore, it is important to choose a lightweight and sturdy children's mirror frame.
