Children's head is very different from that of adults, there, in particular, being apparent difference in the angle and degree of curvature between children's and adults' nose. Therefore, watch carefully of the face and the nose of the children when choosing the frames. Most of children' nose bridges are comparatively low, and the nasal bone is not mature, so the spectacle frame should has a high nose pad, or the frame with adjustable nose pad. Otherwise, the optical frame, after the glasses are put on, will press again face and even come into contact with lash. Glasses like this are just unusable. The children's glasses frame should best be the style of hanging ears, and using elastic belt to tie around the around the back of the head.

Metallic frame isn’t fit children that’s because the bracket of metallic frame will cause allergy to children and press their nasal bone. If the nose pad of metal frames is not adjusted accurately, the phenomenon of oppressing nasal bone will be severer. Besides, metallic frame distorts and brokes easily that will damage its out appearance and the useage. But plastic frame can not be broken easily which is the wise choice for kids' frame. If children like metal frames, it is best for them not to use perforated frames and semi-frames, because these two kinds of spectacle frames are easier to damage.

There should be enough sight range for children reading glasses because children take part in activities in wide range area. Try not to choose those frames which containing shadows and dead points in sight. And avoid the frames which are too big or with too long hangers.
