Apple upended the mid-tier traditional wristwatch market after it showed customers the appeal of buying a device that paired with their iPhones, tracked health metrics, and still told the time. The company now sees a similar opportunity with glasses. It plans to target the broader glasses category with products sold between roughly $200 and $500. The eyewear market is valued at roughly $200 billion annually and hundreds of millions of pairs are sold each year. Apple believes that its strong brand, industrial design, and iPhone integration will lead people seeking new glasses to buy from Apple instead.
