All the eye nightmares can be found in this story.
Mel B originally underwent laser eye surgery to correct her vision, but actually ended up being left with lasting damage in her left eye.
That was 15 years ago.
She is hoping to undergo a full cornea transplant soon in order to correct her blindness.
The 39-year-old explained to Hello magazine: “I can’t see at all out of my left eye. The lasering went wrong so this [operation] will be totally life-changing
The transplant will involve doctors replacing the transparent front part of her left eye with donor tissue.
Mel joked about the idea of having a part of someone else eye on her own, “Hopefully I won’t be seeing what the other person’s seen, the other dead person.”
The X Factor judge was a recent presenter at the MOBO awards, and realised she couldn’t read her autocue.
