My son has beautiful eyes. They are blue, sparkling, and framed by long, dark lashes. And they can see. Both of my children are blessed with wonderful eyesight, a gift that many of us take for granted. It is estimated that 45 million children and adults worldwide suffer from blindness. Every year one to two million more will lose their site, and what is most upsetting is that in 75% of the cases, prevention or early action could have restored sight.
