National Vision Holdings is one of the largest optical retailers in the United States, operating four retail brands—America's Best Contacts and Eyeglasses, Eyeglass World, and Vista Optical locations in select Fred Meyer stores and on military bases—alongside the DiscountContacts.com e-commerce platform. The company's core business comprises selling eyeglasses (from budget to designer brands), contact lenses (including proprietary brands), and eye examination services delivered by employed optometrists and independent practitioners, with an expanding telehealth offering. National Vision generates revenue from retail eyewear and contact lens sales, eye examination fees, and membership subscriptions through its America's Best Eyecare Club, while leveraging procurement scale with major suppliers, centralized laboratory manufacturing, and efficient distribution to drive profitability. The company primarily serves three customer segments: managed-care vision insurance members, customers purchasing with outside prescriptions, and progressive lens wearers seeking premium solutions, positioning itself in the value segment of the fragmented, non-discretionary U.S. optical retail market.
