In the previous article, we discussed “Can you put new lenses in old frames?”. In this article, let’s talk about “Are metal or plastic eyeglass frames better?”.
Advantages of Metal Frames
The metal frame of eyeglasses conforms to the use performance of the frame. They need the material to have high fracture strength, enough plasticity, toughness, and good elasticity. And after the disappearance of the external force, they can restore to the original shape. This is the regular demand for the high elasticity of the metal frame. They must be able to withstand the atmosphere and human sweat daily corrosion. Usually, the corrosion resistance of pure titanium eyewear will be better than other eyewear. Some glasses will have a variety of wonderful grinding designs, and the material must have high plasticity.
Disadvantages of Metal Frames
Metal frames may cause the skin to be sensitive easily. Generally, if the skin allergy to metal, they can choose titanium, but the price is pretty expensive. It may cost thousands of yuan. The frame of the other alloy is not too expensive. Sweat will make the screws and temples of the metal rust, affecting the appearance, which is bad for the skin.
Advantages of Plastic Frames
Plastic is usually called a plate, having no skin allergies. The price is relatively cheap. Colors and styles are diverse. The color is rich, rich in shape. The injection molding material is higher dimensional stability of the whole batch, fast processing speed, and low comprehensive cost. Material prices are lower. It has a certain flexibility.

They need no surface treatment, having noble texture, wear-resisting. Suitable comfort change can be made according to different face sizes. It is the most mature material used in eyewear products of international apparel brands.

PC material comfort is poor, and durability is not good. The frames cannot be changed to suit different face shapes. Because of its good elasticity, TR material can not be changed, which means that poorly made lenses are easy to fit into the frame. Plate material is hard, if the change is not appropriate, it will be not comfortable. Acidic material can not match the lens made of PC material, which will cause the lens to crack.
