A glasses case is a small protective cover that is used to store eyeglasses when they are not being worn. Glasses cases are usually made of materials such as leather, plastic, or fabric, and are designed to protect glasses from damage, dirt, and other external factors. They are typically small and lightweight, making them easy to carry around in a purse, bag, or pocket. Some glasses cases also have additional features such as compartments for cleaning cloths or small tools, or padded interiors to provide extra protection for the glasses.
