Eye wear refers to various types of optical devices designed to assist with vision or protect the eyes. Common forms include glasses, contact lenses, and sunglasses. Glasses typically consist of lenses mounted in a frame that sits on the nose and ears, while contact lenses are thin discs placed directly on the eye's surface. Sunglasses are a specific type of eye wear that protects the eyes from harmful ultraviolet (UV) rays and reduces glare from bright light. Eye wear can also serve fashion purposes, with many styles and designs available to suit individual preferences.
