I've never even heard of getting eyeball tattoos, but apparently this is a thing...
SHOCKER: it's a very bad idea. A Canadian woman named Catt Gallinger may lose her eyesight as a result of trying to tattoo the whites of her eyes.
She's taking medication, but her doctors warn her that she could lose her sight in one eye. Now she's urging others on social media to think twice about sclera tattoos.
