A 50-year-old woman named Theresa Lynch in Sydney, Australia never washed off her mascara before she went to bed for 25 years!
She started to have major eye pain so she went to the doctor, they found that the mascara buildup had created a bunch of permanent BLACK LUMPS embedded in her eyelids.
She needed surgery to have the lumps removed but even though they're gone now, she wound up with scarring on both her eyelids and her corneas that's never going to go away.
Here is the scary part, if the doctors didn't find it or remove it she would have gone blind!
