Clip-on sunglasses are a convenient accessory designed to attach directly to prescription glasses. They provide an easy way to enjoy sun protection without needing a separate pair of sunglasses. Typically, they come in various styles and tints, allowing users to choose the best fit for their needs. These sunglasses are lightweight and easy to use, making them ideal for people who wear glasses regularly. By simply clipping them onto the existing frames, users can quickly switch from indoor to outdoor settings while maintaining clear vision and protecting their eyes from harmful UV rays.
