glasseswearing

Glasseswearing is the practice of wearing eyeglasses, typically to correct refractive errors such as myopia, hyperopia, or astigmatism, but also including sunglasses and protective or non-prescription eyewear. It encompasses a range of devices from everyday prescription spectacles to specialized lenses used for tasks like computer work, reading, or safety in work environments.

Historically, devices to aid vision date to ancient times, but rigid spectacles emerged in 13th-century Europe, enabling many people to read and work more easily. Through the 20th century, mass production and new materials, including lightweight plastics and polycarbonate lenses, made glasses affordable and comfortable. Today, glasses are widely used worldwide by people of all ages.

Glasses consist of frames and lenses. Frames come in metal or plastic and vary in style, fit, and durability. Lenses are ground to the wearer's prescription and may include coatings such as anti-reflective, scratch-resistant, or UV protection. Special categories include bifocal or progressive lenses, safety glasses, sport goggles, and sunglasses, with further variants in lens material and tint.

Use and care involve proper fitting, regular prescription updates, and cleaning to avoid smudges. Practices such as fog prevention and safe handling are common. Glasses can affect social perception and fashion, serving as a functional accessory as well as a style statement. Some lenses are marketed for blue-light blocking or anti-fatigue claims, but evidence for routine benefits is limited.
