Inappropriate frames will affect the effectiveness of glasses
Consumer Daily News
(intern reporter Xie Lei) In recent years, myopia among students in our country has shown a trend of high incidence and younger age. More and more children are wearing "small glasses", and the consumer market of children's glasses has also shown a continuous growth trend, becoming the second The second largest market in the adult market.
With the summer vacation approaching, many parents will bring their children to wear glasses. There are many styles of spectacle lenses and spectacle frames. How to choose a pair of safe and scientific glasses for their children?
The reporter conducted relevant interviews.
Don't Overlook the Importance of Frames
In an optical shop in Panjiayuan Optical City, Beijing, Ms. Tian, a consumer, is taking her child to choose spectacle frames.
She told reporters that she attaches great importance to the quality of children's glasses, optometry is carried out in the eye hospital, and then go to the optical shop to buy lenses and frames.
When asked how to choose glasses frames, she said that color and appearance are the first considerations.
In the interview, Ms. Hetian had the same idea. Many store managers in the optical city said that although many parents recognized the importance of optometry and lenses in children's fitting, they ignored the importance of frames.
Hou Jie, an ophthalmologist at Peking University People's Hospital, told reporters that scientific optometry is the basis of vision correction, lenses are the soul of myopia prevention and control, and frames are the carrier of all these. If there is a lack of suitable frames, whether optometry or lenses, will not be able to play its true role.
He said that because children and adolescents are in a critical period of growth and development, the eyeballs of children and adolescents are more sensitive and susceptible than adults, and children's eyeglass frames actually carry more professional attributes than adult optical frames.
"The weight of glasses directly acts on the bridge of the nose. If it is too heavy, it will easily cause pain in the bridge of the nose. In severe cases, it may cause the deformation of the nasal bone and cause improper pressure on the ears. Because most children are active, the material of the frame should be light. It is not easy to break and the material will not cause irritation to children's skin." Hou Jie said.
The three group standards of "Children's Spectacles", "Children's Spectacle Frames" and "Children's Sunglasses" led by the China Optical Association also mentioned that the materials used in children's glasses are required to minimize the precipitation of harmful substances from parts that have long-term contact with the skin.
Special care should be taken to avoid the use of substances that may be allergic, carcinogenic, mutagenic or toxic.
For children's eyeglass frames worn by children 14 years of age and younger, the surface should be smooth, free of blemishes and bumps, no visible scratches, rounded edges, and no accessible, potentially dangerous sharp edges.
Children's eyeglass frames (metal frames) should have adjustable nose pads.
Fasteners should not create sharp points or bulges that could be touched.
How to choose the right frame
How to choose the right frame?
Hou Jie told reporters that the frames should not be too heavy, the nose pads should be compliant, and attention should be paid to the protection of children's skin, and do not choose frames with irritating electroplating processes.
Hou Jie said that in order to save money, many parents will buy a larger size glasses so that their children can still wear them when they grow up.
But it is wrong to do so, the frame should not be too big or too small, too large glasses will slide down, the pupil center and the optical center point of the glasses will be inconsistent; too small will cause indentation and discomfort on the child's cheeks, which will affect the child's ability to look around. 's vision.
The correct size of glasses should depend on the size of the eye sockets and the distance between the eyes of the child. At the same time, it should not be higher than the eyebrows or wider than the cheeks. Then adjust according to the child's face shape so that the glasses fit the child's nose and ears.
In terms of materials, Hou Jie suggested that the frames can choose pure titanium frames and gel nose pads. The pure titanium frames are lightweight and strong, not easy to break, light and comfortable, and not easy to be allergic. Most skin types can adapt well and are suitable for Use by children.
Gel nose pads are a new accessory that softly rests on a child's nose, allowing the glasses to have the greatest possible contact surface and reducing the impact of glasses on the development of the nose bridge.
The advancement of science and technology has also brought convenience for children to choose frames. The reporter learned that in the past two years, children's custom frames have used 3D scanning technology to build a child's face model. By collecting various parameter points of the face, the parameters are adjusted according to the functional requirements of the lens. , including the inclination angle, lens distance, position, etc., so that the lens is in the best wearing state and maximizes the corrective function of the lens.
Scientific eye is the key
According to data from the National Health Commission, in 2020, the overall myopia rate among Chinese children and adolescents will reach 52.7%, 35.6% in primary school, and 80.5% in high school.
Hou Jie said: "To prevent and control children's myopia, it is better to spend money than to spend money. Scientific use of eyes is the key to preventing and controlling myopia."
He suggested that first, pay attention to the correct posture when reading and writing, sit upright, ensure that the distance between the eyes and the book is about 30 cm, and use electronic devices to be at least 50 cm away from the screen.
The second is to avoid eye fatigue. You need to rest for 5 to 10 minutes after using your eyes for 1 hour. Try not to continue for more than 40 minutes when playing video games.
The third is to strengthen outdoor activities, sunbathe more, and promote the synthesis of vitamin D, thereby preventing myopia.
The fourth is to check eyesight regularly, preferably between 6 months and 1 year.
