To answer the question of "what material is good for glasses frame", we must first understand the use and pertinence of eyeglass online. For example, some allergic skin is not suitable for wearing some irritating skin frames, such as driving, you need to choose a strong impact resistance frame. Different material frames have their own different physical properties. So what are the materials of the frame? What about their respective properties?

Mainstream frame material Material and characteristics

Traditional metal material

Including the traditional copper-nickel alloy frame, the pursuit of strong and durable stainless steel frame, the main lightweight magnesium aluminum alloy frame, and the current relatively high-end titanium alloy frame. The hardness of the metal frame is high, and the eyes are easily injured after the positive impact of the glasses. Therefore, the driver needs to think carefully if he wants to buy metal frames.

Titanium alloy

Titanium is known as the "space metal", light weight, good elasticity, strong corrosion resistance, strong and reliable. The frame made of titanium alloy has good flexibility, long-term use without deformation, skin allergy, and is more practical. Due to the excellent elasticity and shape memory ability of titanium alloy, it stands out among metal frames, especially the safety performance completely gets rid of the restrictions of traditional metal frames.

Plate material

Most of the current plate composition is acetate fiber, and a few high-grade frames are propionate fiber. The gloss of the plate frame is excellent, so the appearance is better when worn. However, plate frames are generally relatively bulky (high material density) and usually brittle and unable to withstand greater impact. Therefore, considering the safety, driving is not appropriate.

Tortoise shell material

Hawksbill is a spectacle frame made of hawksbill shell found in tropical oceans. Tortoiseshell frames are relatively niche high-end products with light weight and beautiful luster. Tortoiseshell frames are brittle and easy to break under impact. Therefore, it is not suitable for driving purposes.

In addition, because the hawksbill turtle production is low, it is particularly expensive, and because the hawksbill turtle has been classified as a protected animal, so there is no sale now.

TR90 material (plastic titanium)

TR90 is a polymer plastic. Lighter than ordinary plate, wear-resistant and high toughness harmless to the human body, good elasticity, bending resistance without breaking. Security is very prominent. Therefore, it is very suitable for driving.

Plastic steel material

Like TR90, it is a high-strength molecular material. It is lighter than the TR90, and the strength and other aspects of the new performance are also a higher level. However, because the nose bridge assembly of the plastic steel frame is generally an independent metal piece installed on the frame by screws, it is not as safe as the TR90 when it is impacted by external forces.

Nylon material

Similar to plastic steel materials, they belong to the same class of materials, material characteristics and the structure including the nose bridge assembly. Basically the same. So no more repetition.

Conclusion:

Driving glasses frame material preferred TR90 material, followed by titanium alloy!
