Spectacles, commonly known as glasses, are optical devices worn on the face to correct vision problems. They consist of a frame that holds lenses in front of the eyes. The lenses can be prescribed to help with nearsightedness, farsightedness, or astigmatism, allowing individuals to see more clearly. In addition to vision correction, spectacles can also serve as a fashion accessory. Many people choose frames that reflect their personal style. Some spectacles come with special coatings, such as anti-reflective or blue light filtering, to enhance comfort and protect the eyes from digital screens and glare.
