Memory glasses can be made to have the same appearance as ordinary metal glasses or titanium glasses, but their functions have been revolutionaryly improved and can withstand repeated twisting, high pressure or drops, quickly restoring their original appearance without damage. But some people may have questions, how expensive are memory glasses? 1. The process of memory glasses is relatively complicated. Compared with ordinary metal glasses and titanium glasses, the welding of memory frames is more complicated. Since the two materials cannot be welded together directly, a layer of nickel metal needs to be plated on the surface and then welded with other metals or titanium. The adhesion of the nickel must be very strong so that it can stick together and be twisted or squeezed repeatedly without falling off. 2. Material cost is high. On one side is memory metal or memory titanium. We only use memory materials imported from Japan or Germany. After receiving the materials, we must conduct repeated tests. After more than 500 times of 90-degree twisting, more than 500 times of 90-degree bending, and -30°C ultra-low temperature testing, the function is still good. Therefore, the quality of materials directly affects the quality of memory glasses. We only use high-quality materials. On the other hand, due to the use of memory material welding, the requirements for ordinary metal or titanium materials are also higher, and the cost will be higher than ordinary metal or titanium frames. 3. The cost of electroplating and color spraying is relatively high. High-quality memory glasses must be able to withstand repeated bending, twisting and even falling back to their original shape, and the surface plating or painting must not have any cracks or damage. Therefore, the requirements for the surface are particularly high, and higher-quality color inkjet materials, more advanced technology, and stricter quality control must be used. Why are memory glasses expensive? To summarize the above points, the costs of technology, materials, and surface treatment are different. A pair of memory metal glasses is about $2 more expensive than ordinary metal glasses of the same style and color. A pair of memory titanium glasses is about $3 more expensive than ordinary titanium glasses of the same style and color.

Here are five details that make acetate glasses different:   Material Composition: Acetate glasses are made from a plant-based plastic material called cellulose acetate. This material is derived from cotton or wood pulp and is processed to create a lightweight yet durable frame material. In contrast, many other types of glasses frames are made from metal or synthetic plastics.   Lightweight: Acetate frames are much lighter than metal frames, making them comfortable to wear for extended periods of time. This is especially beneficial for those who wear glasses all day long.   Flexibility: Acetate is a flexible material, allowing the frames to withstand some bending and flexing without breaking. This flexibility also makes acetate frames more comfortable to wear as they conform to the shape of the wearer's face.   Hypoallergenic: Acetate is hypoallergenic, meaning it is unlikely to cause allergic reactions or irritation for most people. This is an important consideration for those with sensitive skin or allergies to certain metals or plastics.   Color and Design Options: Acetate frames offer a wide range of color and design options. The material can be dyed in various hues, patterns, and finishes, allowing for more customization and personalization compared to metal frames. Acetate frames are also often decorated with intricate detailing and textures, adding a unique aesthetic appeal.
