An optical store is a retail establishment that specializes in selling eyewear, such as prescription glasses, sunglasses, and contact lenses. These stores typically have optometrists or opticians on staff who can perform eye exams and fit customers for glasses or contact lenses. In addition to eyewear, some optical stores may also sell related products, such as eyeglass cases, cleaning supplies, and eye drops. Some stores may also offer repair services for eyeglasses and other eyewear.
