NBC新闻:男孩首次看到颜色激动落泪

What does it mean to see? Watch what happens when Jonathan Jones puts on these special high-tech glasses. Jonathan is extremely color-blind and until this moment had never been able to imagine just how vivid even a classroom could be. His school principal Scott Hanson is color-blind too. 

They're his glasses and you hear how excited he is to share this newly discovered world. Mom, you better get in there, too. That's so awesome. I told you it will be a little emotional. A world most of us of course take for granted. So when we see Jonathan with his smiles and his tears. perhaps he reminds us that the world is indeed beautiful. Why don't you keep those for a little while. Just wait till he gets outside.
