Sonia and Anita, two sisters living in rural India, were both born blind. A simple surgery, costing about $300, could have restored their sight long ago; but their parents, who earn 17 cents an hour planting and harvesting rice by hand, could barely make ends meet. Thanks to the efforts of 20/20/20, a nonprofit working to restore vision to blind children and adults in some of the world's poorest countries, Sonia and Anita were able to undergo that simple surgery on their eyes. When the bandages came off, they saw the world around them for the very first time, and it was captured in a video detailing the sisters' story. Sonia, 12, is said to have gasped as she opened her eyes and blinked into the sunlight for the first time. Her 6-year-old sister, holding her mother close, reportedly declared, "I can see, Mommy." According to 20/20/20, the 15-minute "miracle" surgery, which the sisters both underwent, involves a surgeon removing the defective lens that causes blindness and replacing it with an artificial lens. The procedure could restore the eyesight of half the blind children and adults in the world, the nonprofit says. "The only problem is, for the poorest people in the world, who live on $1 a day, they could never afford to pay for a $300 surgery. So they will remain blind for the rest of their lives -- unless someone helps them," 20/20/20 writes on its website.
