Now, with the popularity of TV computer phones, the number of people with reduced vision has become wider and wider. Looking at the current primary and secondary school students, wearing glasses is very common. When we are nearsighted, choosing a pair of glasses is a helpless and inevitable choice. What kind of material is better for primary school students?
The glasses frame is classified according to the material, mainly tungsten carbon, pure titanium, plate, tr90, magnesium aluminum, alloy, etc. The characteristics of the glasses frames of different materials are also different.
1: Tungsten carbon frame is made of aerospace material tungsten carbon, which has many characteristics such as anti-allergic, super-flexible, high temperature resistance, anti-static and ultra-light.
2: Pure titanium glasses frame It is made of real pure titanium material, which is about 40% lighter than the general alloy frame. It has the advantages of corrosion resistance and hypoallergenic.
3: The sheet material frame is colorful, strong in texture, easy to process, and does not deform under normal temperature.
4: tr90 glasses frame is flexible, elastic and shock-resistant, light weight and other characteristics, suitable for young myopia.
5: Magnesium-aluminum frames are made of magnesium alloy. It has the advantages of abrasion resistance, corrosion resistance, good gloss and strong texture.
6: Alloy material glasses frame features strong, light and beautiful.
Children's optician first needs to wear a firm and comfortable, and then choose the appropriate size and shape according to the thickness of the lens, and finally consider the beauty.
Nose pad: Pay attention to whether the nose pad can stably support on the bridge of the nose, and it will not slip when you bow your head or shake your head. Children in the developmental stage tend to have a flat nose, so it is not suitable for frames without a separate nose pad. There is a conjoined nose pad design to solve the child's flat nose bridge, but because the conjoined plastic is too wide, and the child's nose bridge is narrow, it is often worn on the nose, so that the overall position of the glasses is moved down, although the glasses are stable, But the position of the glasses has changed, which needs attention.
Mirror: The size of the mirror is mainly determined by the size of the glasses. The outer edge of the appropriate lens should be the size of the outer edge of the eye. If it exceeds the face, the size of the frame is too large. If the mirror is only as large as the eye, The temples are bent and the frames are easily deformed.
Arms: Suitable for children's glasses design, the temples should be applied to the skin on the face, with a certain tightening force. This strength, together with the support of the nose pads, stabilizes the equilateral triangle. Some children can hold a finger between the temples and the skin of the face. Just touch the glasses and shift them. Imagine that such glasses are worn on the child's face, and it is too much trouble to use your hands to straighten up. But we also saw some children wearing glasses one or two years ago, the development of the head makes the temples deep in the skin of the face, this imprint has reminded our parents that the children have grown up, the glasses are not suitable.
From the above, it is best to use the TR90 series of glasses frames for children. The TR90 is a memory plate. One is light and comfortable, and the other is not easily deformed. So for kids, choosing the TR90 series is the best option. Titanium frame is also a good choice, pure titanium glasses are light, and it is not easy to fade, titanium is not allergic to the skin, it is suitable for children.
