My toddler recently scratched my cornea with a finger, and while I was completely traumatized, I was able to go to the doctor and allow them to treat me. The phobia is not quite debilitating, just strong.
I have pretty high pain tolerance, but I can't handle eye injuries. I had a scratch on my cornea back in high school and I still remember how there was no ignoring it and nothing that alleviated the pain. Got a corneal ulcer a few months ago from the fancy 24/7 contacts the optometrist sold me. It wasn't near as bad as I remember the scratch being, but I definitely called into work and hid under the covers for a full day.
