A sunglasses strap is a practical accessory designed to keep sunglasses securely in place while being worn. It typically consists of a cord or band that attaches to the arms of the sunglasses, allowing them to hang around the neck when not in use. This helps prevent loss or damage, especially during outdoor activities like hiking or beach outings. Sunglasses straps come in various materials, colors, and styles to suit personal preferences. Some are adjustable for a comfortable fit, while others feature additional elements like rubber grips to ensure the sunglasses stay in place. They are popular among athletes and outdoor enthusiasts for their convenience.
