Eyewear

Eyewear (/ˈaɪwɛər/) refers to items and accessories worn on or over the eyes, primarily for the purpose of improving or protecting vision.

Etymology

The term "eyewear" is a combination of the words "eye" and "wear", first recorded in use in the late 20th century.

Types of Eyewear

There are several types of eyewear, including:

• Glasses: Also known as spectacles or eyeglasses, glasses are frames bearing lenses worn in front of the eyes. They are typically used for vision correction or eye protection.

• Sunglasses: A type of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes.

• Contact lenses: Thin lenses placed directly on the surface of the eyes. Contact lenses are used to correct vision, or for cosmetic or therapeutic reasons.

• Safety glasses: Glasses equipped with safety features that protect the eyes from various hazards.

• Goggles: A form of protective eyewear that usually encloses or protects the area surrounding the eye in order to prevent particulates, water or chemicals from striking the eyes.
