Bono records a special “limerick” for Mario Batali's RED campaign.

Bono, who has had problems with his own vision, is partnering with a company to provide better eye care to the underprivileged.

The "Buy Vision, Give Sight" campaign with eyewear brand Revo is designed to raise $10 million for screening, eyeglasses and other assistance to the impoverished. Revo will donate $10 for each pair of eyeglasses it sells, and the U2 frontman will introduce his own line of Revo sunglasses, which he has been wearing on U2's sold-out tour, in the fall.

Bono, who was diagnosed with glaucoma two decades ago, says his eyesight is OK now. But in a Thursday statement, he said "tens of millions of people around the world with sight problems don't have access to glasses, or even a basic eye test."

He called sight a "human right."

The 55-year-old rocker is known for his activism and philanthropy.
