Stevie Wonder is blind. We know this. Everyone knows this. Wonder, arguably the greatest living maker of popular music, has always been blind. He was born with a condition that caused him to go blind as a baby,

Wonder performed at Cardiff, UK's Blackwater Fields last week (July 9). During the set, he stood up from his piano bench to address the crowd. "I wanted the world to know this," he said. "You know, there have been rumours about me seeing." The crowd initially laughed, before it became clear that Wonder was being entirely serious.

The soul icon — born Stevland Hardaway Judkins — was diagnosed with Retinopathy of Prematurity (ROP) as an infant. Caused by excess oxygen in the incubator used after his premature birth, the condition led to a detachment of the retinas and permanent blindness by the time he was just six weeks old.

Stevie Wonder revealed the “truth” about his impaired vision to a live audience, after longstanding industry jokes and speculation that he is not actually blind. On stage at Blackweir Fields in Cardiff, Wales, during his Love, Light & Song U.K. tour earlier this month, the 75-year-old explained how he is able to “see” people.

One of the greatest musicians of all time is speaking out over longtime rumors about his disability.

Stevie was born premature and went blind shortly after – he was diagnosed with retinopathy of prematurity (ROP) at six weeks old, due to too much oxygen in his incubator. According to the Mayo Clinic, this occurs when blood vessels ‘swell and grow too much in the light-sensing tissue at the back of the eye’.
