These materials not only decrease dependence on virgin plastics but also reduce waste generated during production.

Environmental Impact of Traditional Eyewear Materials

If natural materials like wood or eco-friendly acetate are used, traditional eyewear can have sustainability advantages. These materials generally involve fewer chemicals during production, resulting in less environmental harm. However, some traditional processes (e.g., acetate production) may involve the use of harmful chemicals, negatively impacting the environment. Therefore, when choosing traditional materials, it’s also important to consider the environmental sustainability of the production process.

Cost Considerations

The differences in cost between injection molding and traditional materials are significant:

The largest cost in injection molding eyewear lies in mold creation. Although mold creation is expensive, once the mold is completed, the production cost per unit drops significantly. Therefore, this method is ideal for large-scale production, effectively lowering market prices, particularly suitable for mass-market brands. In contrast, the cost of traditional eyewear primarily involves material and labor, especially in the handcrafting process, making traditional eyewear more expensive and typically positioned in the high-end market.

Market Trends and Consumer Preferences

Market positioning and consumer preferences influence material demand differently:

Injection Molded Eyewear

Injection molded eyewear is highly popular in mass markets, sports eyewear, and fashion brands. It is not only affordable but also quickly responds to market trends by launching new styles that meet consumer needs.
