Whether functional or fashionable, a glasses case provides at the least a rudimentary level of protection. Rugged models use hardwearing materials, often featuring weather and crush resistance, while fashion cases feature attractive designs on the outside and sometimes in the lining.
Designer options tend to use luxurious materials like leather and velvet. Depending on the type, some might fasten shut with a zipper, buttons, magnetic strips, or a drawstring. Keep your eyewear safe inside a high quality glasses case.
