This Lancet Global Health Commission advances addresses SDG 3 directly, and SDGs 1, 2, 4, 5, 8 and 10 indirectly, by comprehensively demonstrating how improving eye health by treating and preventing vision impairment and vision loss can not only advance SDG 3—improving health and wellbeing for all—but also contribute to poverty reduction, zero hunger, quality education, gender equality, and decent work and economic growth. The findings of this report frame eye health as a development issue and highlight that, with a growing ageing population globally, urgent and concerted action is needed to meet unmet eye health needs globally, including incorporating equitable eye care into countries’ universal health coverage plans.
