Eyeglass cases are protective containers designed to hold and safeguard eyeglasses or sunglasses. They come in various shapes, sizes, and materials, such as plastic, metal, or fabric. The primary purpose of an eyeglass case is to prevent scratches, damage, or breakage when the glasses are not in use. Many eyeglass cases feature a hard exterior for added protection, while some have soft interiors to prevent scratches on the lenses. Some cases also include additional compartments for cleaning cloths or lens cleaners. Overall, eyeglass cases are essential accessories for anyone who wears glasses.
