I once took a baby pacifier to the eye from my little sister.
Result:
1. For two years I was totally blind in that eye due to it being filled with blood (could only see total blackness)
2. Had three surgeries to repair the damage and remove the blood.
3. Developed a cataract and had an artificial lens implanted to restore vision (the same kind of lens your grand parents might get)
Lesson Learned:
- You're mom was right... don't throw your toys or you'll put out someone's eye.
