Shenzhen Hengyang Optical Co., Ltd. Company Profile

QUALITY CONTROL is an essential aspect of producing eyewear products that meet international standards for safety and performance. One such standard is SGS quality certification which outlines the requirements and test methods for non-prescription sunglasses and fashion spectacles intended for general use. To comply with this standard, our products meet specific optical, mechanical, and visual requirements and undergo rigorous testing to confirm their compliance.

Our company also seek CE certification, which is a mark of conformity indicating that a product meets European Union safety, health, and environmental protection requirements. This certification shows that a product has undergone rigorous testing and meets high standards for quality and safety.

CE certification is a mark of conformity that indicates that a product meets the safety, health, and environmental protection requirements of the European Union (EU). To obtain CE certification for an eyewear product, manufacturers must comply with a set of standards and undergo testing to confirm compliance. The testing requirements vary depending on the type of eyewear product and its intended use, but may include the following tests:

1. Impact resistance test: This testevaluates the ability of an eyewear product to withstand impact from objects such as rocks, metal debris, or other objects that could cause damage to the lens and potentially harm the wearer's eyes. The test involves dropping a steel ball of a specific size and weight onto the center of the lens from a certain height, and the lens must not crack or shatter to pass.
2. UV protection test: This test evaluates the ability of an eyewear product to block harmful ultraviolet (UV) radiation. The product must meet certain requirements for UV protection, as specified in the relevant EU standards.
3. Frame and hinge strength test: This test evaluates the strength and durability of the frame and hinges of eyewear products. The product must meet certain requirements for strength and durability, as specified in the relevant EU standards.
4. Chemical resistance test: This test evaluates the resistance of eyewear products to chemicals such as oils, solvents, and cleaning agents. The product must meet certain requirements for resistance to chemicals, as specified in the relevant EU standards.
5. Flammability test: This test evaluates the ability of eyewear products to resist ignition and burn under certain conditions. The product must meet certain requirements for flammability, as specified in the relevant EU standards.

​The testing requirements for CE certification of eyewear products are designed to ensure that they meet high standards for safety, health, and environmental protection. By complying with these standards and undergoing testing, manufacturers can provide consumers with products that are reliable, safe, and durable.

For companies that produce sunglasses and fashion spectacles and wish to sell their products in the United States, it's important to note that the Food and Drug Administration (FDA) regulates eyewear as a medical device. Our company also comply with FDA regulations for safety and quality, which may include testing for impact resistance and other factors. When it comes to impact resistance, the drop ball test is a commonly used method for evaluating a product's ability to withstand impact. This test involves dropping a steel ball onto a product from a specific height, and the product must not crack or shatter to pass.

Overall, companies that control by SGS and CE requirements, as well as drop ball testing, are taking essential steps to ensure that their products meet high standards for quality, safety, and performance. This can provide customers with the confidence that they are purchasing products that are reliable, durable, and safe to use.
