Many people take their eyeglasses for granted. And yet, 2.5 billion people around the world, largely in developing countries, live with poor vision because they lack access to eyeglasses, hindering their ability to succeed in school or be productive at work. While the benefits are clear, providing eyeglasses to 2.5 billion people is a challenge, requiring multi-faceted action from a cross-sector group of organizations including healthcare systems, private sector eyeglass manufacturers and retailers, NGOs and social enterprises, and policymakers.
