Glasses
Glasses, also known as eyeglasses or spectacles, are frames bearing lenses worn in front of the eyes used for vision correction.Safety glasses are a kind of eye protection against flying debris or against visible and near visible light or radiation. Sunglasses allow better vision in bright daylight, and may protect one's eyes against damage from high levels of ultraviolet light. Specialized glasses may be used for viewing specific visual information (such as stereoscopy). Sometimes glasses are worn simply for aesthetic or fashion purposes.
