Children need to wear glasses. Parents took their children to the hospital for pupil dilated and optometry , and also got the prescription for glasses . They were nearby in the hospital or on the street glasses shop, or even online, and they equipped their children with glasses. So they breathed a sigh of relief and felt that the problem of wearing glasses was initially solved. Next, they were waiting to wear glasses to check the effect.
But in fact, there are some details that need to be paid attention to when wearing glasses for children. Some details of are directly related to the therapeutic effect of wearing glasses for children . Let’s talk to you about these key details and see if there are any one you have overlooked.
01
Selection frame
Children's glasses can't be as casual as adult glasses.
Put glasses are often an important step in the treatment of eye diseases. For example, treating amblyopia and strabismus , optical correction of crystalless eyes after cataract ; there are still some myopia correction lenses that control the development of myopia, such as "Xin Lexue" and "Xingqu Control" that parents may have heard of. Wearing these glasses not only requires accurate glasses, but also appropriately worn positions. The glasses frame plays a fundamental role in this .
When choosing glasses frames for children, parents and friends must be careful in the following aspects!
1. Select the frame size
0 The frame size should be appropriate. makes the center of the dark eyeball (pupil area) of the two eyes located in the center of the lens, rather than the inner .
Correct glasses Wear vs. Wrong glasses Wear
Everyone knows that when applying glasses, the prescription is marked with pupils from , that is, the distance between the pupils of the two eyes. The center of the pupil is also the center point of the lens. The optician grinds the two lenses into a shape suitable for the frame based on the center and pupil distance of the lens, and then assembles them.
If the frame is too large, it will be difficult for opticians to make the pupil distance of the glasses accurate through the "heart-moving" method. The large difference in pupil distance will affect the optical correction effect of the glasses, and it will also cause the wearer to experience symptoms such as headache, dizziness, and deformed visual objects in . Glasses with large degrees or large astigmatism are particularly prone to symptoms.
The child is still in the growth and development stage. As he grows older, the head, cheeks and pupil distance gradually increases. Parents should choose glasses frames that suit their children and must let their children try on them before purchasing them.
2. Select the frame shape
Frames try to choose the round , the temples are located in the middle of the outer edge of the frame, rather than the upper edge. After the child puts on his glasses, the dark eyeball can be located in the center of the lens instead of the upper edge of the lens (see the correct wearing method in the picture above).
Nowadays, many young people like the fashionable glasses frames, temples are located on the upper edge of the outer edge of the frame. This kind of glasses frame is often inappropriate for children, because the eyes of children can easily cross over the top of the frame if the frame is slightly lowered.
is not recommended for children to choose this framework
Some parents did not find a suitable children's glasses when giving their children glasses. They just made do with a flat and long glasses frame. After the child put it on, the nose pad slides slightly, and the lens slides under the pupils, and the children can't see things through the lenses. Such glasses naturally cannot play their due role.
Incorrect wearing method
3. Selection of frame material
Children's glasses should choose a light and sturdy material . The child's small nose bridge and ears are still developing and are relatively delicate. The heavy glasses not only press the nose bridge and ears, making the child feel uncomfortable, and hence he is unwilling to wear glasses; it may also wear the skin on the nose bridge and ears, and even affect the development of the nose bones.
Therefore, it is important for children to have a light frame. Glasses with high-grade degrees should pay special attention to choosing lightweight glasses frames and light glasses. Children are lively and active, and there is a high possibility of falling and bumping during daily activities. On the one hand, glasses are prone to collision and deformation, and on the other hand, if the frame is broken, it may hurt the child. Therefore, be sure to choose a sturdy glasses frame, and be careful that the glasses are elastic, and the material should not have sharp hard stubble when it is broken. children do not recommend using metal glasses frames .

Selection of lenses
1. Selection of lens material
1 Now the materials of lenses at home and abroad are basically resin materials. Compared with the past glass lens , it is obviously thin and not easy to break. Therefore, it is enough to choose qualified resin lenses produced by qualified manufacturers.
Since children are in the growth and development stage, the diopter of the eyes will also change with age. Usually, glasses may need to be replaced in one or even half a year. Therefore, parents do not have to choose so-called expensive brand high-quality lenses to produce unnecessary excessive consumption.
As long as the lens is transparent enough and the national quality inspection is qualified, it can . The lenses produced by many domestic and foreign manufacturers meet the requirements of children's lens fittings.
2. Selection of lens thickness
In addition to the material, when choosing lenses for children, you should also pay attention to the issue of lens thickness.

If the glasses have a higher degree, the corresponding lenses will be thicker and will inevitably be heavier, and the visual quality will also be affected by the thick lenses. Therefore, you should choose lenses of different thicknesses according to the degree of prescription of children's glasses.
If hyperopia or myopia degree is mild refractive error within 200 degrees (2.00D), the thickness of ordinary lenses is fine; if the degree is higher, you can choose an appropriately thin lens , and there are also so-called ultra-thin lenses. Because the higher the glasses, the thicker the lenses will inevitably be. If the lens material itself has a high refractive index and the lenses are thinner, the height-numbered glasses will be correspondingly lighter and more comfortable.
There are also parents who will pay for the high price of coating or anti-blue light lenses. In fact, generally lenses have coatings. As long as they are qualified lenses, there is no problem with coatings. . For children, it is not recommended to wear , which is . Because anti-blue light lenses will filter out beneficial blue light from natural light, it is not good for myopia prevention and control and eyeball development.

Wear glasses
Now, let’s talk about the details of wearing glasses that need parents’ attention.
Because the child is active and active, his self-management ability is relatively poor. He often does not pay attention to keeping the glasses in a fixed position on the bridge of the nose, but often tilts left and right, or slides down to the wings of the nose (see the picture below). This means that parents need to pay attention to and remind their children to straighten the frame so that their eyes are located in the center of the lens .
Whether it is a convex lens for hyperopia or a concave lens for myopia, The refractive correction effect of glasses is the strongest in the center of the lens, while the peripheral part gradually weakens . If the eye pupils deviate from the center of the lens, the corrective effect of the glasses will be reduced.
After reading the above content, do parents and friends understand? In addition to the accuracy of the degree, the details of wearing glasses for children are also very important!
