I had my vet tech tell me they've seen it happen.
I had a calf born, could see fine, it appeared, but eyes were blueish (black angus/angus cross calf). I didn't think much about it. I checked her to make sure she sucked,then checking twice a day as normal. Three days later blind as a bat. Gave B12 and LA300 and called the vet on Monday, day 4. The girls advised draxxin, Doc was out, so I gave that. Vet tech called me back later and also advised draxxin and said they had been seeing this, calf will be fine. By 7th day eyesight was coming back, and eyes clearing up. She could obviously see me on the eighth day, I put her back on the cow, in the chute, to make sure she still knew how (I had been bottle feeding), and she took right off. Turned them out.
If it wasn't pinkeye, then it was something that affected her eyes. No pinpoint spots that I could detect. I have been told it could be bvd causing it, but vet tech said pinkeye specifically. They didn't see the calf, but pics I had texted them.
