It is very critical to choose a proper spectacle frame when you buy Brille, particularly for children. In particular, kids will not complain about it. If the glasses are inappropriate, parents often mistakenly believe that the child doesn’t like wearing glasses. In fact, the inappropriate glasses are very adverse to the children’s eyes, and will lead the children to have the emotion of hating wearing glasses. The following several aspects need to be taken into consideration while in the choice of kids glasses.
The frames must be light. Normally, the suitable weight of children’s glasses should between 13 grams to 19 grams. Children’s heads are very different from adults’, especially the peak angle of children’s noses, the curvature of children’s noses are more significantly different from adults’. So, choosing the frame for children glasses, you should pay attention to the fat-thin of child’s face, height of nose bridge and so forth. Most children’s bridge of the nose is relatively low and their nose bones are still not full developed. So you should choose high nose pad frames or adjustable nose pad.

Moreover, the dioptre of children varies very fast and parents have to buy new glasses for them almost every year. For this reason, it is more substantial to buy plastic frame from an economic perspective.
Children are not suitable to wear metal frames because the nose bridge of metal frames will cause allergy and press the nose bones. If the nose supports of a pair of metal frames haven’t been adjusted in time, the phonomenon of pressing nose bones will be more serious. In addition, the metal frame is easy to be deformed and broken, which will influence the appearance and use effects. However, the plastic frame is not easy to damage and is a relatively wiser choice for children. If you like the metal frame, you’d better not choose perforated frame and semi-frame, because these two kinds of frames are easy to be damaged.
Children’s Brillengestelle should be sufficient area of vision, because the area of children playing is very wide. Try not to choose the frame which will cast a shadow and vision corners, and also to avoid too big frame or too long hanging corner.
