2: pure titanium lens frame it is made of real pure titanium material, about 40% lighter than the general alloy lens frame.It has the advantages of corrosion resistance and allergy prevention.
3: plate material frames have diverse colors, strong texture, easy processing, and no deformation at room temperature.
4: TR90 frame flexibility, good elasticity, impact resistance, light weight and other characteristics, suitable for sports young myopia is very suitable.
5: Magnesium aluminum lens frame is made of magnesium aluminum alloy material.With wear resistance, corrosion resistance, good gloss and strong texture and other advantages.
6: alloy frame is strong, light and beautiful.
It is recommended to choose the resin material frame.
1: resin eyeglass frame is light, the nasal ratio is low, when wearing, it will not affect the development of the nasal bridge of children:.
2, metal and other materials of the lens frame is heavy, easy to rust, easy to deformation, easy to lead to children's facial allergies and oppression of the bridge of the nose and temple.

Second, pay attention to clean glasses for a little while to prevent wear and tear, there is some dirt on the lens or dirt can use wool or silk cloth graze, don't make clothes, fingers, or anything wipe brush, because it will wear lenses, reduce transparency, long the bottom go to, glass lens would like have a layer of mist shade is not transparent, if you have any oil or other dirty lenses, reoccupy after ha breath that dirt and wet wipe cloth gently wipe the mirror, not hard, or use the hard stuff.
When children are playing sports or doing other strenuous activities, remove the glasses and put them in the glasses case.

Why should the size of children's glasses frame be appropriate?
Glasses worn by children mainly have a therapeutic effect on the eyes, but also objectively play a certain role in beauty.
The size of the lens frame is appropriate or not, directly related to the improvement of children's vision, visual development.
According to children lively, active characteristic, lens wears use plastic more, or organic glass is made.This kind of lens frame side groove is wider, lens installation is firm, soft, children wear comfortable, and not easy to damage, less children indirect eye trauma.Besides, it is cheap and popular with the public.
The size of the frame should be appropriate. Some parents and children think that the frame is bigger and more beautiful, and some think that the frame is smaller and not easy to fall off. These are not comprehensive.
Because, the position of the pupil of children's two eyes is opposite the center of the lens (optical center), and make the surface of the lens and eyeball to maintain the position of 12 mm, can have good correction, treatment effect.If the frame is too big, the eyes of children will be far away from the optical center, to tighten the glasses, a prism effect, cause children eyes see things become unclear, decreased vision, eye pain, fatigue symptoms such as headache, aggravating the development of refractive errors, if the frame is too small, and eyes to the outside, far away from the same lens optical center, due to the long period of time on both sides of the leg press intraocular lens bone, temporal side can also affect the face of the normal development, so the children frames to according to the development of children's head, face and eye socket eye condition choose suitable for their own frames, and along with the continually development of change in time.
