How To Choose Properly Mirror Bracket For Children

While you select eyeglasses, a qualified frame is critical, especially for kids glasses. In particular, the cheeper doesn't have the ability of pouring out. If the glasses are unfit, the parents often think that their child is too piquant to like wearing the glasses. In fact, wearing unsuitable eyeglasses are harmful for kids' eyes which also would make kids feel hateful. Selection of children glasses needs to consider the following several aspects:

The frames must be light. Normally, the suitable weight of children's glasses should between 13 grams to 19 grams. There is big difference between the child's head and the adult's, especially the angle of child's nose peak, the degree of curve about the bridge of nose in comparison with the adult's. That is why we need to pay attention to children’s facial characters, such as big or small face, tall or short nose and the etc when choosing spectacle frame for them. Most children have a short nose bridge and their nasal bones are immature. So the frame with a high or adjustable nose clip will be a good choice. 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 spectacle frame had best be the style of hanging on the ear, using the elastic flex around the back side of head. The binding string shouldn’t be too loose, for fear that the glasses fall from the head of cheeper.

Frames of children cheap glasses have various styles and designs and children also pay much attention on the choices of glasses frames because their pursuit of beauty is no less than that of adults. However, they also need to proceed from reality as well. Most of kids are naughty and playful, so there's often the occurrence of eye injuries because of lens smash. So the glasses should be made of resin, and the frames should be plastic. Those can match with the nose are the most suitable ones. The diopter of children's eyes are changing fast, so the glasses should be changed every year. The plastic frames are more economic.

Children are not suitable for metal frames, because the nose pads can easily cause allergies and oppression on noses. If the nose pad of metal frame is not adjusted properly, the phenomenon of pressing the nasal bone will be more serious. In addition, the metal frame may deform and break easily, which affects the appearance and the result of use. The plastic one in contrast won’t be damaged easily. So it is a smart choice to choose plastic frame for kids. 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 eyeglass frames should be sufficient area of vision, because the area of children playing is very wide. 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.
