Legally blind, not totally blind.
I had really bad strabismus plus vision bad enough that it wasn't possible to correct my vision before I had surgery to fix my eye muscles. Since that didn't happen until I was 4, I spent my first 4 years with vision so bad my dominant eye is classified as 'can see movement' and my non-dominant eye is 'can see light'. Then I had surgery and they could correct my vision.
I'm not sure why it wasn't done earlier.
I have some visual issues related to this early period. I'm terrible with crowding [0], have no depth perception, have trouble with facial feature recognition (I recognize my loved ones based on their auditory cues), rely more on other senses than sight, etc.
My life can basically be broken down into periods based on what medical oddity I dealt with, looking back. Yikes.
