What material is the most durable and what material is the best

Celluloid: A material that has been used for a long time to make glasses. In addition, celluloid is now rare, and it is extremely flammable.

Old celluloid frames, which shrink when baked and heated, were widely used in the manufacture of frames 30 years ago. Acetate: Compared to celluloid, acetate is less flammable.

Generally, the chemical frame is mostly made of this material, and according to the processing method, it can be divided into injection molding and plate rack (milling frame) injection frame: the cost is low, there are seams, rough, and it is used for sunglasses low-grade frame (thermal processing and manufacturing).

Plate rack: manufactured with cold working, fine, ***, durable.

Carbon crystal frame: characterized by high strength, strong, but the material is brittle, after the impact and collision in winter, it is easy to be brittle, and the method to distinguish the carbon crystal frame is to treat the temples with iron and exterior painting. Epoxy:

Light specific gravity, bright color, and good elasticity, long life, epoxy resin was first developed by European eyewear companies mainly used to manufacture CDDUNHIL and other famous brand frames. Epoxy resin is distinguished by the absence of stamens at the temples and the metal stamens of the acetate frame. In addition, the epoxy resin frame is more colorful.

It is the best spectacle frame.

I don't know if you've heard of the TR90 memory frame and the carbon fiber frame, both of which are very durable.

TR90 is a memory polymer material, which has the characteristics of super toughness, impact resistance, wear resistance, and elasticity, so it can better protect the eyes during exercise.

Carbon fiber is a newly developed new type of glasses material, carbon fiber in carbon element has excellent chemical stability, after special processing technology, this material of glasses has high temperature resistance, wear resistance, corrosion resistance, sweat resistance, not easy to allergies, not easy to age and many other characteristics.

Both glasses are very durable, I learned about these from the trioo Cheng lens, I have a carbon fiber frame, I have used it until now, it feels really good, it has been a year, the frame lenses are still new, very good frames, I recommend it to you.

Glasses frames with better materials:

1. Plate frame: This is a more popular plate frame in recent years (Supergirl wears this), the plate is a kind of plastic, but it is much stronger than ordinary plastic, and it is much more beautiful, and the plate will not be allergic, and the formability is good, and it can be made into a variety of fashionable frames.

2. Alloy frames: These frames are made of alloy materials specially suitable for glasses, which not only ensures that the frames have a certain firmness, but also makes the frames have good flexibility and are more comfortable to wear.

3. Pure titanium frame: This frame is a material commonly used in the aerospace industry, titanium. This material is very light in weight (you can compare ordinary frames with pure titanium frames), but also very strong (aerospace materials), non-allergenic, and has strong corrosion resistance.

Made of metal: There are three types of metal materials used for spectacle frames: copper alloy, nickel alloy and nickel alloy. It is required to have a certain hardness, softness, elasticity, wear resistance, corrosion resistance, light weight, gloss and good color, etc.

As a result, almost all of the metal materials used to make spectacle frames are alloys or used after metal surface treatment.

Plastic or resin:Generally, the non-metallic materials used to make spectacle frames mainly use synthetic resins as raw materials, which are divided into two categories: thermoplastic and thermosetting resins.

Considerations for choosing spectacle frames.

Comfortable: Spectacle frames need to feel comfortable when worn, not pressed against the ears, nose or temples, and not too loose.

Spectacle distance: As the name suggests, it is the distance from the spectacle lens to the eye, usually 12mm. If the spectacular eye distance is too far, people with nearsightedness may not see clearly, and people with farsightedness can cause refractive hyperrefraction. The opposite is true if the mirror eye is too close.
