Eyewear is a broad term used to describe any type of device worn on the face that helps to improve vision. This includes glasses, goggles, sunglasses, and other similar items. Glasses are the most common form of eyewear, and they are typically used to correct vision problems such as nearsightedness or farsightedness. Goggles are usually used for protection from the elements, such as wind, dust, or water, and are often worn by athletes or people working in hazardous environments. Sunglasses are designed to protect the eyes from the sun's harmful UV rays, and they come in a variety of styles and colors. All of these items can be referred to collectively as eyewear.
