What is the material of the sunglasses, the material classification of the sunglasses lens material
Mooth classification of Sunglasses lenses
The glass lenses are often exposed to it. The most prominent advantage of glass lenses is that its optical properties are very stable. This is the usual advantage of glass lenses. It is the same on frame glasses.Affected by the pressure of the framework.The disadvantage of glass lenses is that it is easy to break, and it is easy to cause damage to the eyes.At present, the newly developed enhanced glass lenses are more prominent than ordinary glass lenses, and they are also considered a safe lens.
2. Polarized lens
This is a lens used on polarized Sunglasses. The polarization principle of light is used. In the future, the glare obstruction of the parties will be separated from the lens to make the sight clearer and safer when driving.In 1937, Dr. Edwinland in the United States invented this lens and was widely used in polarizing Sunglasses, and he also created his own Pokmon company.
Also known as sensitive lens, due to the change of light, the color of the lens changes accordingly, so that the eyes can adapt to different environments. Under the strong light, the color of the color changing lens will deepen.EssenceThis kind of lens has been used in myopia Sunglasses. This kind of Sunglasses in the form of color -changing lenses are also considered to be the most convenient and most beautiful myopia Sunglasses, which is more popular than clamping.
4. Plastic lenses
This is the material that many Sunglasses brands like very much. Light and not fragmented are its most obvious features. The functions of non -processed plastic lenses are significantly better than glass lenses.EssenceThe disadvantage of plastic lenses is that its wear resistance is easier to scratch. When the lens is impacted, it is also easy to deform, so it should be more careful about its maintenance.
There are three main types of plastic lenses, namely resin lenses, PC lenses, and acrylic lenses.
5. Resin material Sunglasses lens
Friends who often wear glasses must have heard of resin lenses, but what are the resin lenses?Resin (CR-39) is actually a chemical substance of the phenolic structure. It is refined from the phenolic components in oil. The characteristics are light weight, high temperature resistance, strong impact resistance, and can effectively block ultraviolet rays.The great advantage of resin lenses in Sunglasses is that it is easy to color. Many fashionable Sunglasses use resin lenses to favors the characteristics of coloring.But the resin lenses are poor and impact.This type of Sunglasses have a wide range of use and strong decorative effects. It is a good choice for fashion people.
6. PC material Sunglasses lens
PC refers to polycarbonate, a type of plastic (PC). It is a polymer polymer containing carbonate groups in the molecular chain and PC material. In short, it is a Sunglasses material material.There are high -end points, PC films commonly used by professional athletes and colorless or colorless plastic sheets.It is characterized by lightness and good coloring performance. The disadvantage is that the abrasion resistance is low and the optical properties are unstable.PC -made Sunglasses are more suitable for sports people and drivers.
7. AC film (acrylic lens)
It has excellent and tough characteristics, has a high perspective rate, has good anti -mist resistance, the lowest cost, the material is crispy, the rupture may have crumbs, and the stability of optical indicators is average.
8. nylon material Sunglasses lens
nylon Sunglasses are used in sports brands Sunglasses and high -quality big -name Sunglasses. It has high elasticity and excellent optical quality, and has a strong resistance to impact.Professional protection function.However, nylon lenses have poor wear resistance and high production costs.Such Sunglasses are more suitable for people for sports or professional protective mirrors.
9. Tac material Sunglasses lens
TAC Sunglasses are relatively widely practical in China. TAC (triax cellulose, TriaceTyl Cellulose), which is complicated, is one of the high molecular materials with high penetration.TAC has the characteristics of Sunglasses, which has the characteristics of acid -resistant type, light texture, and high cost performance.However, the abrasion resistance has become a soft foot of TAC lenses, and it has its less stable optical characteristics. Although the price of TAC lenses is low in price, it is eventually discarded by most well -known foreign brands.
