 By the end of this year, 1 million men, women, and children will have gone blind. 285 million people worldwide are visually impaired, and 90% of them live in developing countries. Here's an even more sobering fact. Every 60 seconds, somewhere in the world, a child goes blind. They will live their lives unable to see the beautiful world around them if they don't get the treatment they need. Yet 80% of all these cases could have been prevented or treated.
