Lens material
Glass lens
Functional advantages: Excellent optical performance, can provide clear and accurate visual effects, high refractive index, can effectively block UV and some glare. Its hardness is high, not easy to scratch, long-term use can still maintain good clarity.
Quality disadvantage: Glass lenses are heavy, long-term wear may cause greater pressure on the bridge of the nose and ears, affecting the comfort of wearing. Moreover, the glass lens is fragile, easy to break when hit, and the safety is relatively low.
Resin lens
Functional advantages: Light weight, more comfortable to wear, reduce the burden on the head and face. Has good impact resistance, not easy to break, high safety. At the same time, the resin lens can effectively block UV light and glare by coating and other processes, and can also be dyed according to needs to obtain different colors and anti-glare effects.
Quality disadvantage: The hardness of the resin lens is relatively low, it is easy to be scratched, and it is necessary to pay attention to daily maintenance and avoid contact with sharp objects. Its optical properties are slightly inferior to glass lenses, and there may be some dispersion phenomenon.
PC lens
Functional advantages: PC lenses, also called polycarbonate lenses, have extremely high impact resistance, which is more than 10 times that of glass lenses, and are especially suitable for sports sunglasses, which can effectively protect the eyes from damage during intense exercise. At the same time, it is lightweight, comfortable to wear, and can block 100% of UV rays.
Quality disadvantage: PC lens surface hardness is low, easy to produce scratches, the need for special hardening treatment. In addition, its optical performance is good in high-end products, but some low-cost products may have problems such as visual deformation.
Polarized lens
Function advantage: Polarized lens is on the basis of ordinary lenses to add a polarized film, can effectively filter out reflected light and glare, make the field of vision clearer, improve visual contrast and color saturation. In activities such as driving, fishing, and skiing, it can help users see objects and road conditions more clearly and reduce eye fatigue.
Quality disadvantage: The price of polarized lenses is relatively high. If the quality of the polarizing film is not good or the laminating process is not good, there may be problems such as uneven polarizing effect and visual deformation.
Frame material
Metal material
Functional advantages: Metal frames usually have good strength and stability, and can withstand a certain external force without deformation. Its texture is better, the appearance is exquisite, suitable for the pursuit of fashion and high quality consumers. Some metal materials, such as titanium alloy, also have corrosion resistance, anti-allergy and other characteristics, suitable for sensitive skin people wear.
Quality disadvantage: The weight of the metal frame is relatively heavy, which may cause some pressure on the bridge of the nose. Moreover, metal materials may conduct heat at high temperatures, leading to uncomfortable wearing, and may feel cold in cold environments.
Plastic material
Functional advantages: The plastic frame is light in weight, very comfortable to wear, and the price is relatively low, which has a high cost performance. The plasticity of plastic material is strong, and a variety of fashionable styles and colors can be designed to meet the aesthetic needs of different consumers.
Quality disadvantage: The strength of plastic frames is relatively low and easy to break, especially when subjected to large external impact. And the plastic material may aging, discoloration and other problems with the passage of time and changes in the use environment, affecting the appearance and service life of sunglasses.
TR90 material
Functional advantages: TR90 is a new type of polymer material, with ultra-light, ultra-elastic, high temperature resistance and other characteristics. It weighs less than ordinary plastic and is almost stress-free to wear. At the same time, the TR90 frame has good flexibility and elasticity, is not easy to deform, and can adapt to different face shapes and wearing habits.
Quality disadvantage: Although the TR90 frame has good wear resistance, there may still be slight wear during long-term use. And because of its material characteristics, the color of the surface may not be as bright and long-lasting as metal or plastic frames.
Natural material
Functional advantages: Frames made of natural materials such as wood and cutin have a unique texture and natural texture, giving people a natural and simple aesthetic feeling, and have high artistic value and collection value. At the same time, the natural material is relatively environmentally friendly and less irritating to the skin.
Quality disadvantage: Natural material frames need to be carefully maintained to avoid moisture, exposure, etc., otherwise it is easy to deform, crack or mold. And the production of natural materials is limited, the production process requirements are high, so the price is usually more expensive.
