National Vision Holdings, one the largest optical retailers in the U.S., aims to have reopened all its physical stores by early June. They were closed following a nationwide lockdown applied in certain states to combat the Covid-19 pandemic.

The company started opening stores on April 27 and intends to continue doing so selectively over the coming weeks. “During the temporary closure of our stores, we have heard from our customers and patients that they need the critical eye care services we offer,” said the company’s chief executive officer, Reade Fahs.

The company said that all policies and procedures for the reopening align with recommendations of the Centers for Disease Control and Prevention and the American Optometric Association as well as federal and state guidance on social distancing, cleaning procedures, use of personal protective equipment and other safety measures. Additionally, National Vision is implementing expanded health and safety training and procedures for all stores and optometrists practicing in its retail locations.

Throughout the phased re-opening, retail locations that remain temporarily closed to the public will continue to provide services as associates remain available by phone for patients and customers in need. The company’s e-commerce websites, including www.discountglasses.com and www.discountcontacts.com, remain fully operational.

National Vision has more than 1,100 retail stores in 44 states plus the District of Columbia and Puerto Rico. It operates five retail brands: America’s Best Contacts & EyeglassesEyeglass WorldVision Centers inside select Walmart stores, Vista Opticals inside Fred Meyer stores and on select military bases, and several e-commerce websites.
