I found that all the friends finally have some understanding of lenses, but the frame only knows pure titanium, pure titanium, pure titanium
Indeed, there are many advantages of pure titanium, but in fact, each material will have advantages and disadvantages, today focus on the analysis of the advantages and disadvantages of common frame materials on the market, remember to collect.
First of all, the big classification: metal frames and plastic frames, there are currently many metal-plastic ➕ mixed frames
▶️ Metal frames:
❤️ Advantages of pure titanium: suitable for people with a high number, light frame, not easy to rust aging and corrosion, hypoallergenic, etc., usually the frame is marked with the word Titanium
⭕️ Disadvantages: the style is simple, the price is relatively high, you need to pay attention to the most shoddy cases on the market, easy to be pitted (not counting the shortcomings of the material itself)
β titanium advantages: β titanium purity is not as pure titanium, plasticity is generally stronger than pure titanium, cost-effective styles are more, usually the frame is marked with the word β-Titanium
⭕️ Disadvantages: Because of the good flexibility of the temples, the height number may not share the weight of the front end, resulting in frequent decline
Alloy advantages: the price is generally relatively low, the processing difficulty is low, and it is easy to adjust the frame. Usually the color is very bright and the texture is good.
⭕️ Disadvantages: electroplating adhesion is poor, easy to corrode and rust, some people are prone to metal allergies, easy to squeeze deformation, heavier.
Advantages of thin steel: basically stamped and formed with thin sheet stainless steel material, good flexibility, deformation resistance, light weight. Surface IP plating treatment, strong durability.
⭕️ Disadvantages: It is basically internal grooving, which is difficult to process and requires the degree. Lenses with high power are thicker, which affects aesthetics.
▶️ Plastic frames
PC material advantages: material price is lower. It has a certain degree of flexibility and impact resistance.
❌ Disadvantages: The surface spray paint is not environmentally friendly, and the paint layer is easy to peel off. Comfort is poor, durability is not good. The frames cannot be adapted to different face shapes.
TR material advantages: high material transparency. Good flexibility, can accommodate the needs of different sizes, resistant to extrusion.
⭕️ Disadvantages: good elasticity, frames are difficult to adjust, and rough lenses are easy to fit into frames.
Advantages of carbon fiber: light texture, high strength, high temperature resistance, unique texture on the surface.
⭕️ Disadvantages: large bending and easy to break.
Advantages of plate material: high surface hardness, wear-resistant, relatively stronger texture, many international brands will use.
⭕️ Disadvantages: The material is hard and heavy, and the comfort is poor if it is not adjusted properly. Note that the style is basically a one-piece nose pad, which will slide down if it can't stand it.
▶️ Metal-plastic ➕ mixing
❤️ Advantages: The front frame of the plate/TR accentuates the texture of the frame, and the metal temples reduce weight. Basically, there are nose pads, which are easy to adjust, and the height number can also cover the thickness of the lens.
Disadvantages: The style is good-looking, easy to pick and choose (is this a disadvantage)
However, in addition to the choice of material, the comfort, size and width of the face on the frame must be felt by yourself
The height number also considers the balance problem after installing the lenses, and the light spectacle frames and wearing them are not exactly the same thing.
