MASON, Ohio—This month, Luxottica Group’s (NYSE: LUX) Give the Gift of Sight global charitable foundation is asking consumers to help in its mission of providing free eye exams and eyewear to needy people by donating used eyeglasses.

During June, Give the Gift of Sight is conducting its first annual used eyewear collection drive. Consumers can donate their old prescription glasses and non-Rx sunglasses at Give the Gift of Sight partner locations, including LensCrafters, Pearle Vision, Sears Optical and Sunglass Hut stores as well as participating independent eyecare practitioners. Give the Gift of Sight will clean and repair the donated eyewear for distribution on its international missions.

Said Greg Hare, executive director of Give the Gift of Sight, “For a vast majority of people in developing countries, the used glasses we collect are their only chance to have clear vision. The global need for vision care is massive, and we’re asking the public for their support by donating used glasses.”

This year alone, Give the Gift of Sight needs approximately 1.2 million used glasses to support 20 planned missions to developing countries including India, Cambodia, Guatemala, Honduras, the Philippines, Thailand, Mexico, Chile and more, the organization said. Volunteer teams consisting of Luxottica Group associates, ECPs, opticians and program partners travel around the world to hand-deliver free eye exams and recycled glasses to an average of 20,000 adults and children per mission.

So far, Give the Gift of Sight has helped provide clear vision to more than six million people worldwide through more than 135 optical missions to 32 countries.
