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. Many sunglasses also reduce glare, making them useful for activities like driving or outdoor sports. In addition to eye protection, sunglasses can enhance visual comfort and clarity in bright conditions. They are often made with materials like polycarbonate or glass, and some feature polarized lenses to further minimize glare. Wearing sunglasses is a simple way to maintain eye health while enjoying outdoor activities.
