The IAPB Vision Atlas has interactive maps that showcase prevalence and causes data of blindness and vision impairment. Prevalence data is country-level data from 1990 to 2015, with projections to 2020. Causes data too is from 1990 to 2015, with projections–but only at the GBD region level. We also have a new map on near-vision impairment. The data is from the Vision Loss Expert Group. You can access the maps here: http://atlas.iapb.org/gvd-maps/#AllAges Here is a quick video that outlines all the map features.
