glasses, which feature lenses that are coloured or darkened to prevent strong light from reaching the eyes.Many people find direct sunlight too bright to be comfortable, especially when reading from paper in direct sunlight. In outdoor activities like riding, skiing and flying, the eye can receive more light than usual. It has been recommended to wear these kind of glasses whenever outside to protect the eyes from ultraviolet radiation, which can lead to the development of a cataract. Sunglasses have also been associated with celebrities and film actors primarily due to the desire to mask identity, but in part due to the lighting involved in production typically being stronger than natural light and uncomfortable to the naked eye.Sunglasses Since 1950s have been popular as a fashion statement, especially on the beach.
Hiding one's eyes has implications in face-to-face communication: It can hide weeping, being one of the signs of mourning, makes eye contact impossible which can be intimidating, like in the stereotype of the guardian of a chain gang as depicted in Cool Hand Luke, or can show detachment, which is considered cool in some circles. Darkened sunglasses of particular shapes may be in vogue as a fashion accessory. Note that normal glasses are very rarely worn without a practical purpose, curiously, they can project an image of uncool nerdiness that sunglasses do not have. The impact on nonverbal communication and the cool image are among the reasons for wearing sunglasses by night or indoors. People may also wear sunglasses to hide dilated or contracted pupils or bloodshot eyes (which would reveal drug use), recent physical abuse, or to compensate for increased photosensitivity. Fashion trends are another reason for wearing sunglasses, particularly designer sunglasses.
