【Clarity and comfort】: The AC lenses comply with the UV400 standard, helping to prevent eye fatigue and headaches, reducing glare from reflected objects. With a true blocking rate of 90%-100%, they enhance visual sensitivity, making objects appear clearer and brighter compared to most other sunglasses. 【Material Upgrade】: Upgraded AC material differs from ordinary AC and PC lenses, offering superior clarity, protection, comfort, and versatility. The PC frame is made of ultra-light material, providing flexibility and impact resistance while being less prone to wear and tear. Both the nose pad and frame feet are made of PC material, effectively preventing deformation. 【Cutting-edge Design】: The CostarMatter team actively researches popular men's sunglasses styles from various countries and conducts surveys on aesthetic preferences for different age groups. It is through this process that we have designed the Stylish CostarMatter men's sunglasses.
