At first, the boy running around this migrant shelter in Ciudad Juarez, Mexico, appears to be just like any other 8-year-old: Skinny, shy, giggly. You don't even notice his glass eye.
But it's a constant source of worry for his family, who fled Guatemala earlier this year. The boy, Jonathan, lost his eye to a tumor when he was a toddler. Now he needs medicine to keep the eye clean.
"It's a very delicate sickness, very complicated," said his father Giovani, speaking in Spanish through an interpreter. "He needs checkups frequently by medical specialists in the hospital."
