β titanium eyeglass frames have the following advantages:
1. Higher elasticity: β titanium alloy adds small amounts of rare metals such as vanadium and aluminum, thereby increasing the elasticity of the material. Even if twisted, it can recover its original shape, making it suitable for an active lifestyle.
2. Lightweight and Durable: The β titanium eyeglass frame provides a lighter weight while maintaining high durability, making it even lighter than pure titanium.
3. Diverse designs: β titanium has stronger plasticity and can create more diverse eyeglass frame designs, including complex details and innovative shapes.
4. Comfortable fit: The elasticity of β titanium allows the eyeglass frame to better fit the face shape, increasing the comfort of wearing.
However, β titanium eyeglass frames also have some disadvantages:
1. The flexibility of the legs of the glasses may pose certain problems for people of different heights, as they cannot share the weight of the front end, resulting in frequent sliding of the glasses.
2. Elasticity may become a disadvantage when fine-tuning the mirror ring pile head, making adjustment more difficult.
3. The price is not low, and most β – titanium mirror frames use alloy materials for the mirror rings, so the cost is relatively high.
In summary, β titanium eyeglass frames are popular due to their unique elasticity and lightweight durability, but when choosing, one should consider personal needs and taste, as well as possible drawbacks.
