The Selma star appears in a new See America campaign video, titled Stand in the Way of Darkness, and uses his rapping skills to encourage viewers to visit their eye doctors to protect their vision.

In the clip, he says, "The experiences that shape you, the stories that you share, as life unfolds in living colour, capturing every moment, every connection. Now stop. Picture this: The lines begin to blur and the colours fade. The world closes in. Warmth without sunshine... this is vision loss."

"I'm proud to join Allergan in the fight against preventable blindness," Common said in a statement. "Sight is something that far too many of us take for granted."
