Why does Cee Lo Green wear glasses all the time?

Cee-Lo wears sunglasses to complete his "signature look." That look is the "Old-fashioned lady killer," which is reflected in the title of his album the Lady Killer. We found no reported vision problems. Since he's rarely seen without his pair of signature shades we can't help but wonder if a line of Cee-Lo eye wear is in his future. Green was born Thomas DeCarlo Callaway on May 30, 1975 in Atlanta, Georgia.
