Sunglasses are eyewear designed to protect your eyes from harmful sunlight and reduce glare while often providing style and comfort.
Definition and Purpose
Sunglasses are specially designed glasses with tinted or polarized lenses that shield the eyes from ultraviolet (UV) radiation, bright light, and glare. They protect the eyes from potential damage caused by prolonged exposure to the sun, including conditions like cataracts, macular degeneration, and photokeratitis. Sunglasses also help reduce eye strain and improve comfort in bright environments.
Key Features
UV Protection: Quality sunglasses block 99–100% of UVA and UVB rays.
Polarization: Polarized lenses reduce glare from reflective surfaces like water, snow, or roads, improving visual clarity.
Lens Tint: Lenses come in various colors, each offering different visual effects—e.g., gray lenses reduce brightness, brown enhance contrast, and yellow improve low-light visibility.
Material and Coatings: Lenses can be made from glass, plastic, or polycarbonate and often include scratch-resistant, anti-reflective, or mirror coatings.
