I have been blind in one eyed for three weeks. Iatrogenic. It was caused by a staph infection in my eyeball from a doctor’s injection. I may be able to see in that eye again by Thanksgiving. I look like a sophisticated pirate in the meantime.
I just wanted you to know one of my biggest surprises. I didn’t think I could drive because I assumed that I needed two eyes to measure distance. A doctor I trust assured me that I could drive. I did and it was OK. One eye and decades of driving have given me enough visual knowledge to navigate the street scene.
The subsequent surprise was that I have no stereo vision within my first five feet. I can not do any close precise work, such a carpentry, machine tool work or even putting a key in a lock. Cooking and washing dishes are OK because much of that has a large range of tolerance.
The overall surprise was that stereo vision is offset by knowledge at large distances and possibly by movement of the head, but close up, we really are stereoscopic.
