Glasses have become an indispensable part of our lives. They not only help us correct our vision, but also serve as decorations. However, there are many types of glasses on the market, how can we identify glasses based on their materials? This article will introduce how to recognize glasses from their materials in the following aspects.
1、 Common eyewear materials
Plastic: Plastic is a lightweight and easy to process material, therefore it is widely used in the production of glasses. Common plastic materials include polycarbonate, acrylic ester, etc. Plastic glasses are usually relatively inexpensive, but they are prone to scratches and deformation.
Metal: Metal is a high-strength and corrosion-resistant material, therefore it is used to make mirror frames and legs. Common metal materials include nickel, chromium, copper, etc. Metal glasses usually have a delicate appearance, but they are heavy and prone to allergies.
Mixed materials: In order to integrate the advantages of different materials, some glasses adopt a design of mixed materials. For example, the frame may be made of plastic or metal, while the legs may be made of materials such as rubber or silicone.
2、 How to identify different materials
Look at the appearance: By observing the appearance of the glasses, the material can be preliminarily determined. For example, plastic glasses typically have a smooth and glossy surface, while metal glasses exhibit a unique metallic texture.
Listening to sound: Glasses made of different materials make different sounds when colliding. For example, metal glasses typically make a crisp sound during collisions, while plastic glasses make a dull sound.
Weight measurement: Glasses made of different materials also have different weights. For example, metal glasses are usually heavier than plastic glasses, and the material can be determined by weighing the glasses.
3、 Advantages and disadvantages of different materials
The advantages of plastic glasses are lightweight, easy to process, and relatively low price, but the disadvantage is that they are easy to scratch and deform.
The advantages of metal glasses are their delicate appearance, high strength, and corrosion resistance, but their disadvantages are their heavy weight and susceptibility to allergies.
The advantage of mixed materials is that they can combine the advantages of different materials, such as having the strength and corrosion resistance of plastic or metal, as well as the softness and comfort of rubber or silicone. But the disadvantage is that the production process is complex and the price is relatively high.
4、 How to choose suitable materials based on one's own needs
When choosing glasses, we not only need to consider their style and function, but also whether their materials are suitable for our own needs. For example, if we need a pair of lightweight and easy to process glasses, plastic materials may be more suitable for us; If we focus more on exquisite appearance and high strength, then metal materials may be more suitable for us; If we want to have both strength and comfort, then mixed materials may be more suitable for us.
In short, identifying glasses from a material perspective requires us to comprehensively consider various factors, including price, appearance, weight, durability, etc. When choosing glasses, we need to choose the appropriate materials and styles based on our own needs and preferences, in order to better protect our eyesight and improve our quality of life.
