Shades, commonly known as sunglasses, are eyewear designed to protect the eyes from harmful ultraviolet (UV) rays emitted by the sun. They come in various styles, colors, and lens types, providing both functionality and fashion. The lenses can be polarized to reduce glare, making them ideal for outdoor activities like driving or water sports. In addition to protecting against UV rays, sunglasses can enhance visual comfort and reduce eye strain in bright conditions. Many people wear them not only for protection but also as a fashion accessory, with numerous brands and designs available to suit individual preferences.
