Sunglasses are a type of protective eyewear designed to shield the eyes from harmful rays of the sun and bright lights. They are worn in order to reduce discomfort and potential damage caused by ultraviolet (UV) rays, high-intensity light, and glare. Sunglasses typically consist of two lenses, which are made of special materials that have the ability to filter out or absorb specific wavelengths of light, particularly UV rays. These lenses are usually treated with different coatings to enhance their performance, such as anti-reflective coatings to minimize glare.
The frames of sunglasses are typically made of durable materials, such as plastic or metal, which are designed to provide stability and support for the lenses. They are often available in a wide range of shapes, styles, and sizes to accommodate various face shapes and personal preferences.
Sunglasses serve as a practical accessory, protecting the eyes from harmful rays and improving visibility in bright environments. Additionally, they are commonly used as a fashion statement, adding a stylish touch to outfits and enhancing one's overall appearance. Sunglasses have become an essential part of many outdoor activities, such as sports, driving, and leisure, where prolonged exposure to the sun's rays can be detrimental to eye health.

The word "sunglasses" is a compound term derived from two separate words: "sun" and "glasses".
The word "sun" comes from the Old English word "sunne" and is ultimately derived from the Proto-Germanic word "*sunnō". It refers to the star around which the Earth orbits and is the primary source of light and heat.
The term "glasses" comes from the Old English word "glaes", which was used to describe a transparent substance made into lenses for spectacles. This word has its origins in the Late Latin word "glasses" (pl. of "glassum") and the Latin word "glesum", both referring to a gemstone.
