Sunglasses are eyewear with large lenses designed to protect your eyes from direct sunlight, and they work best when they also have broad temple arms to block light coming from the sides. They matter because protecting your eyes from excessive sunlight exposure helps prevent eye damage.

Sunglasses or sun glasses (informally called shades or sunnies; more names below) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. In the early 20th century, they were also known as sun cheaters (cheaters then being an American slang term for glasses).
