Cheap reading glasses can cause eye strain.
The optical quality of cheap reading glasses is often not as good as that of custom glasses for computer use and reading. Moreover, cheap reading glasses often offer no protection against the high-energy blue light emitted from computer screens and other digital devices.
Beta titanium
β titanium refers to a particle titanium material that is completed by delayed cooling at the zero bound point state of titanium and does not belong to the alloy. Practical applications will often be processed into alloys to increase their applicability. Although the purity of β titanium is not comparable to pure titanium, its strength, fatigue resistance, and environmental corrosion resistance are better than pure titanium. It has higher strength than pure titanium and other titanium alloys, and the corrosion resistance is stronger and has better elasticity, It is not easy to deform, and is lighter.
The MEMORY METAL 202 EYEGLASSES
Memory Metal 202 is an eyeglass frame and it is designed for children who fall over and their parents who must wear glasses. This development allows the metal to withstand a certain amount of bending and then return to its original shape. In addition to being incredibly flexible, the material is very not heavy, very thin, and very comfortable. The rectangular shape is popular with children with a sense of fashion. The choice of colors suits both boys' and girls' tastes and skin tones. Starting with a smooth pink hue, the thin nature of the metal ensures that the color keeps subtle through the soft blue selection.
What are bendable glasses called?
Bendable frames, or memory metal frames, are metal frames that can be twisted, bent, and shattered without breaking or losing their original shape. It's made of a kind of smart metal that has a memory. Its microstructure has two relatively stable states. At high temperatures, the alloy can be changed into any shape you want. Memory metals are mainly nickel-titanium alloy and other materials. The structure of these alloys varies with temperature in the solid-state, the shapes of these alloys can be changed as needed, and will automatically return to their original shape at a given temperature. One unique aspect is its ability to return to its original shape, although the frame has been twisted, bent, or crushed. They are lighter and more durable than traditional metal frames. The bendable frames are made of composite metal alloys for bending properties. These lenses can be twisted and bent, and when they are released, they return to their original shape.
Which is better:the silicone nose pad or the air cushion nose pad?
Although the air cushion nose pad is more flexible and has less pressure, in the process of actual use, the pressure on the bridge of the nose is not much different from that of an ordinary silicone nose pad. And because of the hollow design of the air cushion nose pad, the material on the front surface is easily damaged due to lack of thickness. If not taken care of, the metal nose brace can be directly applied to the bridge of the nose. if do not pay attention to the cause metal stents directly affect the bridge of the nose, with bad security. And the hollow design will bring dirty things, so it is easy to get dirty, affecting the image.

Glasses are used as accessories.
Glasses can be used to outline your face. Most glasses have a positive effect on the temperament and image of the person, provided that the choice is proper. The function of the spectacle frame, in addition to its supporting the lens to form glasses to wear on the eyes of the people to play a support role, also has a beautiful, decorative role. Modern fashionable person emphasizes glasses should have harmony with the facial makeup and dress of person, reflecting social class, high learning, elegant fashion, and so on. When the spectacle frame is worn by people in the streets and alleyways, those who are not nearsighted begin to pay attention and feel that wearing a chic spectacle frame is a very fashionable behavior.
