Safety glasses Industry knowledge

In today's society, glasses are more than just a tool for vision correction; they are a fusion of fashion and function. Zhejiang Qiliang Optical Technology Co., Ltd., a technology-based enterprise integrating the research and development, design, manufacturing, sales, and service of eyewear materials, understands that eyewear requirements vary across different scenarios. Therefore, its product line encompasses a wide range of styles, including optical glasses, sunglasses, reading glasses, sports glasses, and protective glasses, to meet diverse customer needs.

Safety Glasses utilize advanced optical polymer polymerization technology to create lenses with high transmittance and low distortion, providing a clear and comfortable visual experience. The frames are lightweight and comfortable, making them suitable for extended use.
We're focusing on a pair of protective glasses. Made from durable materials, these lenses offer high hardness and toughness, effectively protecting the wearer's eyes from splashes and chemicals. The ergonomically designed frames are comfortable and suitable for use in industrial, laboratory, and construction environments. These protective glasses also feature high gloss and a high cost-effectiveness, making them an ideal choice for safety protection.

Let's introduce a pair of sports glasses. These sports glasses are made of lightweight materials, featuring lenses with high transmittance and low haze, providing a clear field of view and helping the wearer maintain good vision during exercise. The sturdy frame design effectively prevents the glasses from falling off during exercise, ensuring the wearer's safety. These sports glasses also feature high refractive index and low diamond content, reducing light reflection and refraction, providing a more comfortable visual experience.

Zhejiang Qiliang Optical Technology Co., Ltd. specializes in the research and development of polymerization, modification, and thin film composite processes for various optical polymer materials, and continuously invests in the development of new upstream optical materials based on market trends. The company collaborates with Zhejiang Kaixin Optoelectronics Co., Ltd. to develop lenses, frames, and environmentally friendly recycled materials. They particularly recommend PTR modified materials, which offer high hardness, high gloss, high toughness, high cost-effectiveness, and paint-free environmental protection, making them suitable for frame manufacturing. The company's newly developed AMS resin polarized lenses offer advantages over traditional TAC lenses, such as high hydrophobicity, high transmittance, high refractive index, low distortion, low haze, low diamond content, and no stress-induced rainbow patterns, providing a clearer and more comfortable visual experience.
