Sunglasses refer to protective eyewear designed to prevent bright sunlight, high-energy visible light, and harmful ultraviolet (UV) rays from damaging or discomforting the eyes. They also function as a fashion accessory, often associated with style, elegance, and sophistication, and can be adorned with precious metals or gemstones similar to jewelry. As an integral part of fashion, sunglasses can enhance an individual's personal style, complementing their attire and overall appearance.
