In recent years, Chinese students have shown high incidence and aging trend. More and more children have put on "small glasses". The children's glasses consumer market has also continued to grow, becoming the second largest market after the adult market. When the summer vacation is approaching, many parents will bring their children to match glasses. The styles of glasses and glasses racks are full of style. How to choose a safe and scientific glasses for children? The reporter conducted relevant interviews.

Don't ignore the importance of the frame

In a glasses shop in Panjiayuan Glasses City in Beijing, Ms. Tian Ms. Tian is taking her children to choose the glasses frame. She told reporters that she attaches great importance to the quality of children's glasses. The optometry is carried out at the ophthalmology hospital, and then goes to the glasses shop to buy lenses and frames. When asking how to choose a glasses rack, she said that color and face value is the first consideration. During the interview, there are still many thoughts of Ms. Hetian. Many store managers in Graduation City have said that although many parents recognize the importance of optometry and lens in children's compatibility, they ignore the importance of mirror frames.

Hou Jie, an ophthalmologist at Peking University People's Hospital, told reporters that scientific optometry is the basis of vision correction. The lens is the soul of myopia prevention and control. It will not be able to play its real role. He said that because in a critical period of growth and development, children and adolescents are more sensitive and affected than adults. Children's glasses racks actually carry more professional attributes than adult optical frames. "The weight of the glasses is directly acting on the bridge of the nose. If it is too heavy, it is easy to cause sore nasal bone bone, which may cause the nasal and bone deformation and cause improper compression of the ears. Because most children are active, the material of the frame should be lightweight. It is not easy to break and the material will not stimulate children's skin. "Hou Jie said.

The three group standards of "Children's Fixed Matching Glasses", "Children's Glasses Rangers" and "Children's Morroscopy" led by the China Glasses Association also mentioned that the materials used by children's glasses are required to reduce harmful substances from components that have been exposed to the skin as much as possible. Pay special attention to avoid using substances that may cause allergies, carcinogenic, induces organic mutations or toxic. For children's glasses racks worn by children 14 and below, the surface should be smooth, hairless and convex, no obvious scratches, round edges, and should not be triggering, potentially dangerous and sharp edges. Children's glasses rack (metal frame) should have adjustable nasal support. The fastening parts should not produce sharp points or raised or even touched dangers.

How to choose the right frame

How to choose the right frame? Hou Jie told reporters that the frame should not be too heavy, and the nasal support must also be taken. It also pays attention to the protection of children's skin. Do not choose a frame with irritating electroplating process.

Hou Jie said that in order to save money, many parents will buy large glasses for children to grow up when they grow up. But this is wrong. The glasses rack should not be too large or too small. Too large glasses will decline, the pupil center and the optical optical center point of the optical optical optical is inconsistent; Vision. The correct size of the glasses should depend on the size of the eye socket and the distance between the children's eyes. At the same time, it should not be higher than the eyebrows or widen the cheeks, and then adjust according to the child's face shape to make the glasses and the child's nose and ear shapes.

In terms of material, Hou Jie suggested that the frame can choose pure titanium mirror frames and gel nose support. The lightweight material of pure titanium frame is strong, not easy to break, light and comfortable, and not allergic. Children's use. Gel nose support is a new accessory that can softly lean on the child's nose, which can allow the glasses to have as much contact as possible, reducing the effects of glasses on the development of the nose.

The advancement of science and technology has also brought convenience to children's choice. The reporter learned that the children's custom mirror frame in the past two years uses three -dimensional scanning technology to build children's facial models. Including tilt angle, mirror eye distance, location, etc., let the lens in the best wear state, maximize the correction function of the lens.

Scientific eye is the key

According to data from the National Health and Health Commission, the overall myopia rate of Chinese children and adolescents in 2020 reached 52.7%, the primary school stage was 35.6%, and the high school stage had reached 80.5%. Hou Jie said: "Prevent and control children's myopia, spending money is worse than spending, scientific eyes is the key to preventing myopia."

He suggested that the first is to pay attention to the correct posture when reading and writing. The body is sitting positively to ensure that the distance between the eyes and books is about 30 cm, and the use of electronic equipment is at least 50 cm from the screen. The second is to avoid eye fatigue. You need to rest for 5 to 10 minutes with your eyes for an hour. Play video games and try not to last 40 minutes. The third is to strengthen outdoor activities, expose the sun, and promote synthetic vitamin D to prevent myopia. The fourth is to check vision regularly, it is best to be between 6 months and 1 year.
