I need your help!

Hi.
I saw a clip on facebook not to long ago about a father and a daugher. The only thing i remember is the father started to get blind, and the girl started to cry and ask if he could se her, she ran infront of his coworkers and cry alot, but i can't remember what she said, because it was so sad..  I really want to see this! 

Does anybody know what this drama/movie is called?
