Sunglasses lens Manufacturers

Sunglasses lens is an optical lens designed to protect human eyes from harmful ultraviolet radiation and strong light stimulation. The core function is to provide full-band UV protection of UV400 (effectively blocking UVA and UVB), and significantly reduce the intensity of visible light, improving visual comfort and clarity. According to the functional characteristics, it is mainly divided into polarized lenses (effectively filtering scattered glare and enhancing visual contrast, especially suitable for scenes such as water, snow and driving) and non-polarized (dyed/tinted) lenses (mainly providing light attenuation and UV protection). The lens material is commonly lightweight and impact-resistant polycarbonate (PC) or nylon with excellent optical properties. The surface can be coated with a multi-layer film to enhance wear resistance, anti-reflection and waterproof and anti-fouling properties. The choice depends on the specific purpose, lighting environment and personal visual needs.

Sunglasses lens Industry knowledge

When choosing the right sunglasses, not only does the appearance and Sunglasses lens type matter, but the material is also crucial. The two most popular lens materials on the market are polycarbonate (PC) and nylon, each with its own advantages and suited to different wear needs.

Polycarbonate (PC) lenses are renowned for their exceptional impact resistance, making them the safest of all lens materials. They are virtually shatterproof, effectively protecting the eyes from accidental impacts and flying objects. Furthermore, PC is extremely lightweight, reducing strain on the nose and ears, making it ideal for extended wear. Due to its mature production process, PC lenses are generally more cost-effective, making them a popular choice for both sports and casual wear. If you're an outdoor enthusiast who values safety and practicality, PC lenses are undoubtedly an ideal choice.

Nylon lenses represent the highest standard of optical performance. Their defining characteristic is their exceptional clarity, providing unparalleled visual experience, reducing edge distortion and chromatic aberration, and ensuring a more vivid and clear field of view. Nylon lenses also offer the advantages of being lightweight and comfortable to wear. It also offers excellent high-temperature resistance and flexibility, resisting deformation due to thermal expansion and contraction. Due to its complex manufacturing process and high cost, nylon lenses are primarily used in high-end or designer sunglasses.

As a technology-based enterprise integrating the research and development, design, manufacturing, and sales of eyewear materials, Zhejiang Qiliang Optical Technology Co., Ltd. boasts four titanium frame production lines and 60 imported injection molding machines, enabling us to manufacture eyewear products in a variety of materials for global customers. We deeply understand the characteristics and advantages of different lens materials and are committed to incorporating cutting-edge material technologies into our products to meet the needs of diverse markets. Our products are exported to countries including the United States, Europe, Japan, and South Korea.

Whether you choose PC or nylon for Sunglasses lens depends on your personal needs and lifestyle. If you frequently engage in high-intensity outdoor activities or require high-security protection, PC lenses are a wiser choice. On the other hand, if you prioritize comfort, superior optical performance, and clear vision, nylon lenses are your best choice.
