A new interview with ESPN Deportes shows that Sosa may not be wearing the contacts, but his skin has become even lighter.
Some reacted to the change on Twitter.
Despite speculation that Sosa, who once looked African-American in skin color, wants to look white, he has said that he is not trying to change his skin color.
"It's a bleaching cream that I apply before going to bed and whitens my skin some," Sosa said in a 2009 interview. "It's a cream that I have, that I use to soften (my skin), but has bleached me some. I'm not a racist, I live my life happily."
