Bono, who has had problems with his 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 $10m (€9.1m) 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.
Bono, who was diagnosed with glaucoma two decades ago, said his eyesight is OK now.
